Background

The Bearing (Bearing) is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient (friction coefficient) in its motion process, and guarantee its gyration precision (accuracy). The rolling bearing is divided into a ball bearing and a roller bearing according to a rolling force body.

Roller bearings rely on rolling contact between primary parts to support rotating parts. Different roller bearings may be subjected to different radial and axial forces. In selecting a roller bearing, the choice will be made according to the particular operating conditions. The roller bearing mainly comprises a self-aligning roller bearing, a thrust self-aligning roller bearing, a tapered roller, a cylindrical roller bearing and other structural types; there is no prior art bearing that fits between the bearing inner diameter dimensions 40 and 45 in the actual national standard. A certain limitation arises when the hydraulic motor supports the output shaft.

In order to solve the above problems, a non-standard cylindrical roller bearing is proposed in the present application.
