BNR bearing Super high speed angular contact ball bearings

BNR bearing can bear radial and axial loads in one direction at the same time, with high speed, mainly used in precision machine tools and other high-precision, high-speed parts. When this type of bearing bears radial load, the inner ring of the bearing will generate axial component force. Therefore, single row angular contact ball bearings usually need to be installed and used with bearings that can bear the axial direction in the opposite direction.

Application:

BNR bearing have a high limit speed, can bear radial load and axial load at the same time, and can also bear pure axial load. The axial load capacity is determined by the contact angle and increases with the increase of the contact angle. increase. Single row angular contact ball bearings can only bear axial load in one direction. When bearing radial load, it will cause additional axial force, and the corresponding reverse load must be applied. Therefore, this kind of bearings are generally used in pairs.

Features:

Design features of BNR bearing:

Rolling bearings are not only the first choice for the spindle of general cutting machine tools, but also favored by high-speed cutting machine tools due to their good rigidity, high precision, strong bearing capacity and relatively simple structure. From the viewpoint of high speed, angular contact ball bearings are the best among rolling bearings.
