LFR Support Roller Bearing Introduction:
LFR support roller bearing has U groove on outer ring. It belongs to double row angular contact ball bearing.
For this series bearing,
- Support roller bearings are made of high-quality bearing steel or stainless steel, processed by heat treatment and precision grinding, and filled with long-life, high-quality, multi-purpose grease.
- LFR series guide rail roller bearings are the most widely used, economical and practical products among linear guide rollers. They can be adapted to cylindrical guide rails with stable operation, small error, extremely low operating noise and high operating speed.
- The contact between the roller and the guide rail is two-point 60-degree contact, which has good contact performance and low running resistance, so as to achieve a relatively long service life.
- The roller adopts the internal structure design of double row angular contact ball bearing and the thickened outer ring, so that the roller has a higher load carrying capacity.
The roller bearing is equipped with an eccentric wheel and a concentric shaft and is easy to install. - Dust-proof roller adopts metal dust cover (KDD) or rubber sealing cover (NPP).
Bearing Features:
1. High speed, low resistance, long life
2. Simple and convenient installation
3. Smooth operation, small error, and extremely low operating noise
