NEW UPDATED ANGULAR CONTACT BALL BEARING

Product catalog summary

Overview of Angular Contact Ball Bearings

Angular contact ball bearings are designed to handle both radial and axial loads. They are commonly used in high-speed and high-precision applications such as machine tool spindles, high-frequency motors, gas turbines, oil pumps, air compressors, and printing machines.

Single-Row Angular Contact Ball Bearings

These bearings can carry radial loads and axial loads in one direction. When subjected to radial loads, they generate an axial force component, necessitating the use of two bearings in a back-to-back or face-to-face arrangement for stability. The contact angles between the rings and balls are typically 15°, 25°, and 40°. A larger contact angle increases the axial load capacity, while a smaller angle allows for higher rotational speeds.

Double-Row Angular Contact Ball Bearings

Double-row bearings come in two designs: one with a single outer ring and two inner rings, and another with one outer ring and one inner ring. The design with two inner rings allows for easier control of axial clearance during machining.

Specifications and Performance

The document provides detailed specifications for various models of angular contact ball bearings, including dimensions, load capacities, limiting speeds, and mass. Key parameters include:

Dimensions: Diameter (d), Outer Diameter (D), Width (B)
Load Ratings: Dynamic (Cr) and Static (Cor)
Limiting Speeds: Maximum speeds for grease and oil lubrication
Mass: Weight of the bearing

Table Summary

The tables list numerous bearing models with their respective specifications. For example, the 7900C model has a diameter of 22 mm, a width of 6 mm, and can handle dynamic and static loads of 52,000 N and 69,000 N, respectively, with limiting speeds of 12,500 rpm for grease and 19,500 rpm for oil.

Conclusion

Angular contact ball bearings are essential components in various high-speed and precision applications. Understanding their specifications and proper arrangement is crucial for optimal performance and longevity.

NEW UPDATED ANGULAR CONTACT BALL BEARING-1

Angular contact ball bearings When the single-row angular contact ball bearing is carrying the radial load, there will be a component of force in the axial direction.Therefore it is suggested that two of these bearings be applied in back-to-back or face-to-face arrangement. These bearings have contact angles between the rings and balls. The standard angles are 15°、25°、and 40°.The greater the angle, the higher the axial load carrying capacity of the bearing. However, the smaller contact angle, the higher the rotating speed. Single row bearings can carry radial load and axial load in one direction. Double-row angular contact ball bearings have two designs of one outer ring and two inner rings and one outer ring and one inner ring. For the design with one outer ring and two inner rings, the axial clearance is easy to control during machining. Angular contact ball bearings are applied for high speed and high precision rotating condiations. These bearings are mainly applied in the machine tool spindles,high-frequency motors, gas turbines, oil pumps,air compressors, printing machines and other installations.
