What is a radial thrust bearing?
The axial load state angular contact ball bearings can withstand a direction, in radial load, will cause additional axial force. The axial displacement and can limit shaft or shell in one direction. If the duplex mounting, so that a pair of bearing outer ring relatively wide end face, wide face, narrow end face with narrow end. So to avoid the additional axial force, but also in the two direction of the shaft or shell limit in the axial clearance range.Look at the radial thrust bearings and angular contact ball bearings, they will find that they are the same kind of bearings. Just according to different classification methods have produced two names just
If only in terms of bearings for rolling bearing loads under different classification, rolling bearings can be summarized into radial bearings (mainly bear radial load, thrust bearing) (only axial load), thrust bearing (can bear radial and axial load). Radial thrust ball bearings, bearing the structure and can bear radial load and axial load in one direction. And the inner and outer rings with 15 degrees, 25 degrees, 30 degrees from 40 degrees. The contact angle of the contact angle increases, the axial load bearing capacity is large.
The contact angle is smaller, more conducive to high-speed rotation. Usually, two bearing internal clearance adjustment is opposite after use.Angular contact ball bearings (Angular Contact Ball Bearings) can also bear radial load and axial load. Can work at a higher speed. The larger the contact angle, the axial bearing capacity is higher. The high precision and high speed bearings usually take 15 degrees contact angle. Under the action of axial force, contact angle will increase.
