High-precision wear-resistant angular contact ball bearings

High-precision wear-resistant angular contact ball bearings

The angular contact ball bearing has raceways in the inner ring and outer ring that are displaced with respect to each other in the direction of the bearing axis, which means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads.
The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle "α":
Angular contact ball bearing is especially suitable to be subjected to the combination of radial and axial load compared with other types of ball bearings. The bigger the contact angle is, the higher axial load withstanding ability it has.
The high precision and high speed angular contact ball bearings usually adopts 15°angle.
The angular contact ball bearing could be divided into two types according to the quantity of roller rows, that are single row and double rows angular contact ball bearings.
Conventionally, there are three assembly ways for the angular contact bearings, back to back type(i.e 7000/DB) ,face to face type(i.e 70000DF) and series assembly type(i.e 70000/DT).
Applications such as lathe main axle, high frequency motor, food machinery,oil pump, fan and blower, and others are recommended to use the angular contact ball bearings, either single row or double rows type.

Double row angular contact ball bearings can withstand larger radial load and axial joint load and torque load, limit the axial displacement of the two aspects. Mainly used for limiting the axial displacement of the shaft and the shell.
Double row angular contact ball bearing inner and outer ring of the tilt between the limited, allowing the tilt angle depends on the internal clearance of the bearing, bearing size, internal design and role in bearing the force and torque, and the maximum allowable inclination angle should ensure that the bearing will not produce high additional stress.
