LBCN BEARING offers ANGULAR CONTACT BEARING, including single row, double row and high temperature series.

1. Represents different

AC is the code of the domestic bearing; A is the angle code of the Japanese bearing; C is the angle code of the Japanese bearing.

2. Different contact angle and force
AC contact angle of 25 degrees is subject to axial force and radial force; A contact angle of 30 degrees is subject to axial force and radial force; C contact angle of 15 degrees is mainly to withstand radial force and small axial force, For high-precision, high-speed equipment.

Angular contact ball bearings can bear 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 have a 15-degree contact angle. Under the action of axial force, the contact angle will increase. Single row angular contact ball bearings can only bear the axial load in one direction, and will cause additional axial force when bearing radial load.

And can only limit the axial displacement of the shaft or housing in one direction. If it is installed in pairs, make the outer rings of a pair of bearings face each other, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face. This avoids causing additional axial forces and confines the shaft or housing to the axial play in both directions.
