Angular Contact Ball Bearings

Angular Contact Ball Bearings

Angular Contact Ball Bearings Bear radial load and axial load simultaneously. Can work at higher speed. The larger the contact angle, the higher the axial bearing capacity. The contact angle is the angle between the line of contact of the ball in the radial plane and the raceway and the vertical line of the bearing axis. High-precision and high-speed bearings are usually 15 degrees contact angle. In the axial force, the contact angle will increase

Description

Angular contact bearings can withstand both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load carrying capacity. High precision and high speed bearings typically take a 15 degree contact angle. Under the axial force, the contact angle will increase. High-speed precision angular contact ball bearings are mainly used for high-speed rotating applications with light loads. High-precision bearings, high-speed, low-temperature, low-rise vibration and a certain service life are required. The support members of the high-speed electric spindle are often used in pairs, and are the key components of the high-speed electric spindle of the inner surface grinding machine.

Installation form

Angular contact ball bearings are available in a selection of automatic contact models. The angular contact ball bearings are available in back-to-back, face-to-face and series arrangement. When installed back to back (the wide end faces of the two bearings are opposite), the contact angle of the bearing spreads along the direction of the rotation axis, which increases the radial and axial support angle rigidity and the maximum deformation resistance; face to face (the narrow end faces of the two bearings are opposite) When installed, the contact angle of the bearing converges toward the direction of the rotation axis, and the support angle is less rigid. Since the inner ring of the bearing protrudes from the outer ring, when the outer rings of the two bearings are pressed together, the original gap of the outer ring is eliminated, and the preload of the bearing can be increased; when the series arrangement (the wide end faces of the two bearings are in one direction) is installed The contact angles of the bearings are the same and parallel, so that the two bearings share the working load in the same direction. However, in order to ensure the axial stability of the installation when using this type of mounting, two pairs of bearings arranged in series must be mounted opposite each other at both ends of the shaft.
