Description

Novel radial roller bearing

Technical Field

The utility model relates to the technical field of bearings, in particular to a novel radial roller bearing.

Background

The rolling bodies of the radial roller bearing are cylindrical rollers, and have larger lengths, larger load bearing capacity and higher rigidity than the radial ball bearing. The contact line between the roller and the inner ring and the outer ring of the bearing is a straight line, so that the roller has small friction and rolling resistance when bearing large radial load.

Maintaining a good lubrication state of radial roller bearings is crucial to ensure their proper operation and extended service life, and it is extremely necessary to check the lubrication state of the bearings regularly and to replace the lubricant regularly. Outdated lubricants may lead to reduced lubrication performance, increased friction and wear.

To this end we propose a novel radial roller bearing.
