Design features and characteristics 1.1  Angular contact ball bearing Angular contact ball bearings are non-separable bearings with a defined contact angle in the radial direction relative to the straight line that runs through the point where each ball makes contact with the inner and outer rings (see Fig. 1). Table 1 provides information on contact angles and their designated codes. In addition to radial loads, angular contact ball bearings can accommodate single direction axial loads. Since an axial load is generated from a radial force, these bearings are generally used in pairs. Table 2 shows general angular contact ball bearing characteristics, Table 3 shows information on using duplex (side by side) angular contact ball bearings, and Table 4 shows information on multiple-row angular contact ball bearings. For bearings with a contact angle of 15° and bearing tolerance JIS Class 5 or higher, see special catalog “Precision rolling bearings (CAT. No. 2260/E)”.     1.2  Four-point angular contact ball bearings Four-point angular contact ball bearings have a contact angle of 30° and a split inner ring. As shown in Fig. 2, when the inner and outer rings receive a radial load, the ball contacts the inner and outer rings at four points. This construction enables a single bearing to accommodate axial loads from either direction, and when under a simple axial load or heavy axial load, the bearing relies on two contact points like ordinary bearings.   1.3  Double row angular contact ball bearings The structure of double row angular contact ball bearings is designed by arranging two single row angular contact bearings back-to-back in duplex (DB) to form a single bearing with a contact angle of 25°.These bearings are capable of accommodating radial loads, axial loads in either direction, and have a high capacity for moment loads.As shown in Fig. 4, sealed and shielded type double row angular contact ball bearings are also available. Standard loads vary from those of open type bearings.

NTN 32214U Single Row Tapered Roller Bearing (Inside Dia - 70mm, Outside Dia - 125mm)   SPECIFICATIONS Type of Product : Single Row Tapered Roller Bearing Inside Diameter (d) (mm) : 70 Outside Diameter D (mm) : 125 Width Dia mm : 31 Model No : 32214U 1. Types, design features, and characteristics Tapered roller bearings are designed so the tapered vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the centerline of the bearing (see Fig. 1).The tapered rollers are guided by the compound force of the inner and outer raceway surfaces which keep the rollers pressed up against the large rib on the inner ring.A large variety of these bearings, including single, double, and four row arrangements, are available in both metric and inch series. Each type and associated characteristics are shown in Table 1. For four-row tapered roller bearings, see section “C. Special application bearings.”   Table 1  Tapered roller bearing types and characteristics Type Characteristics Single row taperedroller bearings  (1) There are both metric and inch series adhering to the standards shown in the following table. Dimension series ＊Dimension series previously not covered by 3XX are regulated under JIS B 1512; dimensions previously missing from 3XX will henceforth use the bearing number. (2) In addition to the standard design, there are also medium contact angle and large contact angle types, denoted by the contact angle codes at the end of the part numbers (C and D, respectively). (3) Subunits Tapered roller bearings can be disassembled into parts: the inner ring, rollers, and cage (collectively known as the “CONE”) and the outer ring (known as the “CUP”). These are the bearing’s “subunits”. Subunit dimensions are standardized under ISO or ABMA standards, and unified subunits are interchangeable within each dimensional standard. However, high precision grade bearings are generally not interchangeable, and these subunits must be used by assembling only subunits with identical manufacturing numbers.Aside from any cautionary notes that may appear, the single row tapered roller bearings listed in the dimension tables have subunits standardized for both metric and inch systems (including J series). (Refer to Fig. 2) Single row taperedroller bearings (4) These bearings are constructed to have a high capacity for radial loads, axial loads, and combined loads. The larger the contact angle, the greater the axial load capacity. When a pure radial load is applied to a tapered roller bearing, an induced load in the axial direction is also generated, so these bearings are generally used in pairs.(5) Single row tapered roller bearings are separable, so both the inner and outer rings can be used with tight fits. (6) Tapered roller bearings are also manufactured with flanges attached to the outer rings. For more details, contact NTN Engineering. (Refer to Fig. 3) Duplex tapered roller bearings (1) When two single-row tapered roller bearings are to be used in combination, the bearing clearance and preload are adjusted by the inner ring spacer or the outer ring spacer (see Fig. 4).(2) A product number and a combination code are indicated on inner rings, outer rings, and spacers. Parts displaying the same number and code must be used in combination.(3) See A-96 Table 8.14 for the axial internal clearance. Double row taperedroller bearings (1) Back-to-back arrangement (using double row outer rings) and face-to-face arrangement (using double row inner rings) are both available. The assemblies have been adjusted so that each type's internal clearance values are fixed. Only parts with identical manufacturing numbers can be used and they must be assembled according to their code numbers. (Refer to Fig. 5)(2) See A-96 Table 8.14 for the axial internal clearance of double-row and duplex bearings.    2.  Standard cage type In general, pressed cages (see Fig. 6) are used in tapered roller bearings. For large sized bearings, machined or pin type cages may also be used, while resin cages may also be used for smaller sized bearings. 3.  Allowable misalignment In order to avoid edge loading and potential for premature failure, the maximum allowable misalignment based on bearing series can be found below.The allowable misalignment of combined bearings is influenced by the load center position, so please consult NTN Engineering.• Single row (standard) …………… 1/ 2 000• Single row (ULTAGE) …………… 1/ 600   4.  Precautions If bearing load is light during operation, or if the ratio of axial to radial load for duplex and double row bearings exceeds the value of e, slipping may develop between the rollers and raceway surface, sometimes resulting in smearing. The mass of rollers and cages particularly tends to be large for large tapered roller bearings. For additional details, please contact NTN Engineering.In tapered roller bearings, the cage may protrude beyond the inner and/or outer ring side faces. Care should be taken when designing the housing and shaft to ensure contact with the cage does not occur.

NTN 22336EMD1C3 Spherical Roller Bearing (Inside Dia - 180mm, Outside Dia - 380mm) SPECIFICATIONS Type of Product : Spherical Roller Bearing Inside Diameter (d) (mm) : 180 Outside Diameter D (mm) : 380 Width Dia mm : 126 Model No : 22336EMD1C3 1. Design features and characteristics Spherical roller bearings consist of an outer ring having a continuous spherical raceway and two rows of barrel-shaped rollers guided by an inner ring with two raceways. (Refer to Fig. 1) This bearing has self-aligning properties, and therefore is suited for use where misalignment between the inner and outer rings occurs from housing installation error or shaft bending. Spherical roller bearings have a large capacity for radial loads, axial loads in either direction, and combined loads. They are also suited for applications where vibration and shock loads are encountered. When spherical roller bearings are used with a vertical shaft or under a large axial load, the load on the rollers of the row that is not subject to the axial load becomes small, and the resulting skidding on the rollers may result in wear. If the ratio of the axial load to the radial load exceeds the factor e in the dimension table (Fa/Fr > e), consult NTN Engineering.In addition to spherical roller bearings with cylindrical bores, spherical roller bearings with tapered bores are also available. Bearings with tapered bores are specified by the suffix “K” at the end of the spherical roller bearing part number. The standard taper ratio is 1:12 for bearings with a “K” suffix; for bearings in series 240 and 241, the suffix “K30” indicates the taper ratio for a bearing is 1:30. Most tapered bore bearings incorporate the use of adapters and withdrawal sleeves for shaft mounting.

Design features and characteristics 1.1  Angular contact ball bearing Angular contact ball bearings are non-separable bearings with a defined contact angle in the radial direction relative to the straight line that runs through the point where each ball makes contact with the inner and outer rings (see Fig. 1). Table 1 provides information on contact angles and their designated codes. In addition to radial loads, angular contact ball bearings can accommodate single direction axial loads. Since an axial load is generated from a radial force, these bearings are generally used in pairs. Table 2 shows general angular contact ball bearing characteristics, Table 3 shows information on using duplex (side by side) angular contact ball bearings, and Table 4 shows information on multiple-row angular contact ball bearings. For bearings with a contact angle of 15° and bearing tolerance JIS Class 5 or higher, see special catalog “Precision rolling bearings (CAT. No. 2260/E)”.     1.2  Four-point angular contact ball bearings Four-point angular contact ball bearings have a contact angle of 30° and a split inner ring. As shown in Fig. 2, when the inner and outer rings receive a radial load, the ball contacts the inner and outer rings at four points. This construction enables a single bearing to accommodate axial loads from either direction, and when under a simple axial load or heavy axial load, the bearing relies on two contact points like ordinary bearings.   1.3  Double row angular contact ball bearings The structure of double row angular contact ball bearings is designed by arranging two single row angular contact bearings back-to-back in duplex (DB) to form a single bearing with a contact angle of 25°.These bearings are capable of accommodating radial loads, axial loads in either direction, and have a high capacity for moment loads.As shown in Fig. 4, sealed and shielded type double row angular contact ball bearings are also available. Standard loads vary from those of open type bearings.

Design features and characteristics 1.1  Angular contact ball bearing Angular contact ball bearings are non-separable bearings with a defined contact angle in the radial direction relative to the straight line that runs through the point where each ball makes contact with the inner and outer rings (see Fig. 1). Table 1 provides information on contact angles and their designated codes. In addition to radial loads, angular contact ball bearings can accommodate single direction axial loads. Since an axial load is generated from a radial force, these bearings are generally used in pairs. Table 2 shows general angular contact ball bearing characteristics, Table 3 shows information on using duplex (side by side) angular contact ball bearings, and Table 4 shows information on multiple-row angular contact ball bearings. For bearings with a contact angle of 15° and bearing tolerance JIS Class 5 or higher, see special catalog “Precision rolling bearings (CAT. No. 2260/E)”.     1.2  Four-point angular contact ball bearings Four-point angular contact ball bearings have a contact angle of 30° and a split inner ring.

Design features and characteristics Deep groove ball bearings are very widely used. A deep groove is formed on the inner and outer ring of the bearing enabling the bearing to sustain radial and axial loads in either direction as well as the complex loads which result from the combination of these forces. Deep groove ball bearings are suitable for high speed applications. When two or more deep groove ball bearings are used in combination and mounted adjacent to each other a duplex set (D2) should be used. Duplex bearings (D2) utilize controlled tolerances to more evenly distribute the loading between the individual bearing rows which improves the overall performance of the assembly. In addition to unsealed and unlubricated “open” bearings, NTN provides deep groove ball bearings that are pre-lubricated with grease and enclosed by seals or shields. See section “11. Lubrication” for a list of some of the greases which can be used. Table 1 shows the construction and special characteristics of various sealed deep groove ball bearings.    Types and codes N Shielded type Shielded type Non-contact type ZZ Non-contact type LLB Contact type LLU Low torque type LLH Construction Metal shield plate is affixed to the outside ring; the inner ring incorporates a V-groove and labyrinth clearance.

NTN 4T-30209 Single Row Tapered Roller Bearing (Inside Dia - 45mm, Outside Dia - 85mm)   SPECIFICATIONS Type of Product : Single Row Tapered Roller Bearing Inside Diameter (d) (mm) : 45 Outside Diameter D (mm) : 85 Width Dia mm : 19 Model No : 4T-30209 1. Types, design features, and characteristics Tapered roller bearings are designed so the tapered vertex of the raceway surfaces of the inner and outer rings and rollers converge at one point on the centerline of the bearing (see Fig. 1).The tapered rollers are guided by the compound force of the inner and outer raceway surfaces which keep the rollers pressed up against the large rib on the inner ring.A large variety of these bearings, including single, double, and four row arrangements, are available in both metric and inch series. Each type and associated characteristics are shown in Table 1. For four-row tapered roller bearings, see section “C. Special application bearings.”   Table 1  Tapered roller bearing types and characteristics Type Characteristics Single row taperedroller bearings  (1) There are both metric and inch series adhering to the standards shown in the following table. Dimension series ＊Dimension series previously not covered by 3XX are regulated under JIS B 1512; dimensions previously missing from 3XX will henceforth use the bearing number. (2) In addition to the standard design, there are also medium contact angle and large contact angle types, denoted by the contact angle codes at the end of the part numbers (C and D, respectively). (3) Subunits Tapered roller bearings can be disassembled into parts: the inner ring, rollers, and cage (collectively known as the “CONE”) and the outer ring (known as the “CUP”). These are the bearing’s “subunits”. Subunit dimensions are standardized under ISO or ABMA standards, and unified subunits are interchangeable within each dimensional standard. However, high precision grade bearings are generally not interchangeable, and these subunits must be used by assembling only subunits with identical manufacturing numbers.Aside from any cautionary notes that may appear, the single row tapered roller bearings listed in the dimension tables have subunits standardized for both metric and inch systems (including J series). (Refer to Fig. 2) Single row taperedroller bearings (4) These bearings are constructed to have a high capacity for radial loads, axial loads, and combined loads. The larger the contact angle, the greater the axial load capacity. When a pure radial load is applied to a tapered roller bearing, an induced load in the axial direction is also generated, so these bearings are generally used in pairs.(5) Single row tapered roller bearings are separable, so both the inner and outer rings can be used with tight fits. (6) Tapered roller bearings are also manufactured with flanges attached to the outer rings. For more details, contact NTN Engineering. (Refer to Fig. 3) Duplex tapered roller bearings (1) When two single-row tapered roller bearings are to be used in combination, the bearing clearance and preload are adjusted by the inner ring spacer or the outer ring spacer (see Fig. 4).(2) A product number and a combination code are indicated on inner rings, outer rings, and spacers. Parts displaying the same number and code must be used in combination.(3) See A-96 Table 8.14 for the axial internal clearance. Double row taperedroller bearings (1) Back-to-back arrangement (using double row outer rings) and face-to-face arrangement (using double row inner rings) are both available. The assemblies have been adjusted so that each type's internal clearance values are fixed. Only parts with identical manufacturing numbers can be used and they must be assembled according to their code numbers. (Refer to Fig. 5)(2) See A-96 Table 8.14 for the axial internal clearance of double-row and duplex bearings.    2.  Standard cage type In general, pressed cages (see Fig. 6) are used in tapered roller bearings. For large sized bearings, machined or pin type cages may also be used, while resin cages may also be used for smaller sized bearings. 3.  Allowable misalignment In order to avoid edge loading and potential for premature failure, the maximum allowable misalignment based on bearing series can be found below.The allowable misalignment of combined bearings is influenced by the load center position, so please consult NTN Engineering.• Single row (standard) …………… 1/ 2 000• Single row (ULTAGE) …………… 1/ 600   4.  Precautions If bearing load is light during operation, or if the ratio of axial to radial load for duplex and double row bearings exceeds the value of e, slipping may develop between the rollers and raceway surface, sometimes resulting in smearing. The mass of rollers and cages particularly tends to be large for large tapered roller bearings. For additional details, please contact NTN Engineering.In tapered roller bearings, the cage may protrude beyond the inner and/or outer ring side faces. Care should be taken when designing the housing and shaft to ensure contact with the cage does not occur.
