NTN 6015LLU Deep Groove Ball Bearings , D=75   SPECIFICATIONS Type of Product : Deep Groove Ball Bearing Model No : 6015LLU Width : 20 mm Inner Diameter : 75 mm       1. 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.

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.

NTN N213 Cylindrical Roller Bearing (Inside Dia - 65mm, Outside Dia - 120mm) Features Type of Product : Cylindrical Roller Bearing Inside Diameter (d) (mm) : 65 Outside Diameter D (mm) : 120 Width Dia mm : 23 Model No : N213     1.  Types, design features, and characteristics Cylindrical roller bearings can accommodate heavy radial loads due to the line contact formed between their rolling elements and raceways. These bearings are also suitable for high speed applications since the rollers are guided by either inner or outer ring ribs. Cylindrical roller bearings are separable, allowing them to be easily installed and disassembled even when interference fits are required.Among the various types of cylindrical roller bearings, E type and EA type have a high load capacity while maintaining standard boundary dimensions. HT type has a large axial load capacity, and HL type provides extended fatigue life in poor lubrication conditions. Multiple row bearing arrangements are also available.For extremely heavy load applications, the non-separable full complement SL type bearing offers special advantages. For SL type and four- row cylindrical roller bearings, see section “C. Special application bearings.”Table 1 shows the various types and characteristics of single row cylindrical roller bearings. Table 2 shows the characteristics of non-standard type cylindrical roller bearings. Table 1  Cylindrical roller bearing types and characteristics Type code Design  Characteristics NU type N type -NU type outer rings have two ribs. The outer ring, roller, and cage assembly can be separated from the inner ring. N type inner rings have two ribs. The inner ring, roller, and cage assembly can be separated from the outer ring.-Unable to accommodate any axial loading. -This is widely used as the floating side bearing in a fixed-float arrangement. NJ type NF type -NJ type has two ribs on the outer ring, a single rib on the inner ring; NF type has a single rib on the outer ring, and two ribs on the inner ring.-Can receive single direction axial loads. -When there is no distinction between the fixed side and floating side bearing, these types can be used as a pair in close proximity. NUP type NH type (NJ＋HJ) -NUP type has a collar ring attached to the ribless side of the inner ring; NH type is NJ type with an L type collar ring attached. All of these collar rings are separable, and therefore it is necessary to fix the inner ring axially. -Can accommodate axial loads in either direction. -Widely used as the shaft’s fixed-side bearing    Table 2  Non-standard type cylindrical roller bearing characteristics Designation Characteristics E type and EA type Cylindrical roller bearing -Boundary dimensions are the same as the standard type, but the diameter, length and number of the rollers have been increased, resulting in higher load capacity. -Identified by the addition of “E” to the end of the basic roller number. -Enables compact design due increased load rating. -Rollers’ inscribed circle diameter differs from the standard type rollers and therefore cannot be interchanged. -EA type bearings are ULTAGE series1). Note: In the dimension tables, both E type and EA type are listed. Cylindrical roller bearing for axial loads (HT type)  -Can accommodate larger axial loads than the standard type due to improved geometry of the rib roller end surface. -Please consult NTN Engineering concerning necessary considerations, such as load, lubricant, and installation conditions. Double-row cylindrical roller bearing -NN type and NNU type are available. -Widely used for applications requiring thin-walled bearings, such the main shafts of machine tools, rolling machine rollers, and in printing equipment. -Internal radial clearance is adjusted for the spindle of machine tools by pressing the tapered bore of the inner ring on a tapered shaft. Remarks: For precision bearings for machine tools, see precision rolling bearings   2.  Standard cage type Table 3 shows the standard cage types for cylindrical roller bearings. The basic load ratings listed in the dimension charts correspond to use of the standard cages listed in Table 3. The basic load ratings listed in the dimension tables are for standard configurations. These ratings can change when a different cage type and number of rolling elements is utilized. Note: 1. Within the same bearing series, cage type is constant regardless of the cylindrical roller bearing type (NJ, NUP, N, NF).2. For high speed and other special applications, machined cages can be manufactured when necessary. Consult NTN Engineering.3. Among EA type bearings that use resin cages as standard, certain varieties use pressed cages. Consult NTN Engineering.4. Although machined cages are the standard for two-row cylindrical roller bearings, resin cages may also be used in some of these bearings for machine tool applications.

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.

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.
