NTN 6313LLU Deep Groove Ball Bearings , D=65   SPECIFICATIONS Type of Product : Deep Groove Ball Bearing Model No : 6313LLU Width : 33 mm Inner Diameter : 65 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.

NTN 7000CP5 Angular Contact Bearing - D=10 Angular contact ball bearings are non-separable bearings in which the straight line connecting the contact points between the balls and the inner and outer rings has a certain angle (contact angle) with respect to the radial direction, and a radial load and an axial load in one direction are applied. Can be done.In addition, when a radial load acts, an axial component force is generated, so two are generally used facing each other. SPECIFICATIONS Inner Diameter d (Φmm) 10 Contact Angle (°) 15° Outer Diameter D (Φmm) 26 JIS Grade 5 Width B (mm) 8 Race Ring Shape Angular contact ball bearing Outer Ring Type Flat Material (Main Unit) High carbon chromium bearing steel Rolling Element Material High carbon chromium bearing steel Shield Shape Open type Load Direction Radial Angular Contact Ball Bearings 1. 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.

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. 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.

Similar to radial bearings, thrust bearing designs may incorporate balls or rollers as rolling elements.The configuration and characteristics of each type of bearing are given below.With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping between the bearing’s rolling elements and raceways.For more detailed information, please refer to section “8.3 Bearing preload.” 1.  Single direction thrust ball bearings As shown in Fig. 1, the steel balls of single direction thrust ball bearings are arranged between a pair of a pair of washers (shaft washer and housing washer), and the normal contact angle is 90°. Axial loads can be supported in only one direction, and radial loads cannot be accommodated. These bearings are not suitable for high speed operation.Table 1 lists the standard cage types for single direction thrust ball bearings               2.  Thrust spherical roller bearings Just like spherical roller bearings, the center of the spherical surface for thrust spherical roller bearings is the point where the raceway surface of the housing raceway washer meets the center axis of the bearing. Since thrust spherical roller bearings incorporate barrel-shaped rollers as rolling elements, they also have self-aligning properties. (See Fig. 2) Under normal load conditions, the allowable misalignment is 1/60 to 1/30, although this will vary depending upon the bearing’s dimension series.These bearings use machined copper alloy cages and a guide sleeve for the cage is attached to the inner ring. These bearings have a high axial load capacity, and can accommodate some radial load when the ring is axially loaded. It is necessary to operate these bearings where the load condition meets Fr / Fa ≦ 0.55.The design for spherical thrust bearings is such that lubricant cannot enter the gap between the cage and the guide sleeve. Therefore, oil lubrication should be used, even in low speed operation.                 3. Thrust cylindrical roller bearings Thrust bearings incorporating cylindrical rollers are available in single row, double row, triple row, and four row varieties. (See Fig. 3) NTN Engineering offers the 811, 812 and 893 series that conform to dimension series 11, 12 and 93 prescribed in JIS, as well as other special dimensions.While thrust cylindrical roller bearings are only able to receive axial loads, the axial loads can be heavy due to the high axial rigidity of the bearing. For series 811, 812, and 893, the dimension tables are listed section “E. Needle roller bearings.” Bearings with dimensions not listed in the dimension tables are also manufactured.

Similar to radial bearings, thrust bearing designs may incorporate balls or rollers as rolling elements.The configuration and characteristics of each type of bearing are given below.With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping between the bearing’s rolling elements and raceways.For more detailed information, please refer to section “8.3 Bearing preload.” 1.  Single direction thrust ball bearings As shown in Fig. 1, the steel balls of single direction thrust ball bearings are arranged between a pair of a pair of washers (shaft washer and housing washer), and the normal contact angle is 90°. Axial loads can be supported in only one direction, and radial loads cannot be accommodated. These bearings are not suitable for high speed operation.Table 1 lists the standard cage types for single direction thrust ball bearings             2.  Thrust spherical roller bearings Just like spherical roller bearings, the center of the spherical surface for thrust spherical roller bearings is the point where the raceway surface of the housing raceway washer meets the center axis of the bearing. Since thrust spherical roller bearings incorporate barrel-shaped rollers as rolling elements, they also have self-aligning properties. (See Fig. 2) Under normal load conditions, the allowable misalignment is 1/60 to 1/30, although this will vary depending upon the bearing’s dimension series.These bearings use machined copper alloy cages and a guide sleeve for the cage is attached to the inner ring. These bearings have a high axial load capacity, and can accommodate some radial load when the ring is axially loaded. It is necessary to operate these bearings where the load condition meets Fr / Fa ≦ 0.55.The design for spherical thrust bearings is such that lubricant cannot enter the gap between the cage and the guide sleeve. Therefore, oil lubrication should be used, even in low speed operation.                 3. Thrust cylindrical roller bearings Thrust bearings incorporating cylindrical rollers are available in single row, double row, triple row, and four row varieties. (See Fig. 3) NTN Engineering offers the 811, 812 and 893 series that conform to dimension series 11, 12 and 93 prescribed in JIS, as well as other special dimensions.While thrust cylindrical roller bearings are only able to receive axial loads, the axial loads can be heavy due to the high axial rigidity of the bearing. For series 811, 812, and 893, the dimension tables are listed section “E. Needle roller bearings.” Bearings with dimensions not listed in the dimension tables are also manufactured.

Similar to radial bearings, thrust bearing designs may incorporate balls or rollers as rolling elements.The configuration and characteristics of each type of bearing are given below.With thrust bearings, it is necessary to supply an axial preload in order to prevent slipping between the bearing’s rolling elements and raceways.For more detailed information, please refer to section “8.3 Bearing preload.” 1.  Single direction thrust ball bearings As shown in Fig. 1, the steel balls of single direction thrust ball bearings are arranged between a pair of a pair of washers (shaft washer and housing washer), and the normal contact angle is 90°. Axial loads can be supported in only one direction, and radial loads cannot be accommodated. These bearings are not suitable for high speed operation.Table 1 lists the standard cage types for single direction thrust ball bearings             2.  Thrust spherical roller bearings Just like spherical roller bearings, the center of the spherical surface for thrust spherical roller bearings is the point where the raceway surface of the housing raceway washer meets the center axis of the bearing. Since thrust spherical roller bearings incorporate barrel-shaped rollers as rolling elements, they also have self-aligning properties. (See Fig. 2) Under normal load conditions, the allowable misalignment is 1/60 to 1/30, although this will vary depending upon the bearing’s dimension series.These bearings use machined copper alloy cages and a guide sleeve for the cage is attached to the inner ring. These bearings have a high axial load capacity, and can accommodate some radial load when the ring is axially loaded. It is necessary to operate these bearings where the load condition meets Fr / Fa ≦ 0.55.The design for spherical thrust bearings is such that lubricant cannot enter the gap between the cage and the guide sleeve. Therefore, oil lubrication should be used, even in low speed operation.                 3. Thrust cylindrical roller bearings Thrust bearings incorporating cylindrical rollers are available in single row, double row, triple row, and four row varieties. (See Fig. 3) NTN Engineering offers the 811, 812 and 893 series that conform to dimension series 11, 12 and 93 prescribed in JIS, as well as other special dimensions.While thrust cylindrical roller bearings are only able to receive axial loads, the axial loads can be heavy due to the high axial rigidity of the bearing. For series 811, 812, and 893, the dimension tables are listed section “E. Needle roller bearings.” Bearings with dimensions not listed in the dimension tables are also manufactured. Contact NTN Engineering for more information. 4.  Thrust tapered roller bearings Although not listed in the dimension tables, tapered roller bearings like those in Fig. 4 are also manufactured. Contact NTN Engineering for more detailed information.
