LFR5208-40-KDD Double row angular contact bearings” detailed introduction

Arc Groove Guide Roller-LFR Series

LFR5208-40-KDD Track Roller Bearing dimensions 40x98x38mm

Series guide rollers are widely used, economical and practical products among linear guide rollers, which can be adapted to cylindrical guide rails.
2. The contact between the roller and the guide rail is two-point contact, which has good contact performance.
3. The roller adopts the internal structure design of double row angular contact ball bearing and the thickened outer ring, which gives the roller a load-bearing capacity.
4. The roller is made of high-quality bearing steel, processed by heat treatment and precision grinding, and filled with long-life, high-quality, multi-purpose grease. The roller dust-proof adopts metal dust cover (KDD) or rubber sealing ring (NPP).
■ The roller guide system with LFR series guide rollers has the following characteristics:
1. High allowable speed, low resistance, long life
The outer ring surface of the LFR series guide rail roller is designed into a Gothic shape, so that when the roller is working, the roller and the guide rail form two-point contact with an angle of 60 degrees. The friction resistance is small and the load is even. It avoids the installation and The stress concentration and boundary effects caused by manufacturing errors make the guide rail system have the characteristics of high speed, low energy consumption and long life.
2. Simple and convenient installation
After the rollers are equipped with eccentric shafts and concentric shafts, the installation is very convenient. Adjust the eccentricity of the eccentric rollers to obtain a suitable preload.
3. Smooth operation, small error, extremely low operating noise
DEEG’s processing equipment and testing equipment ensure the accuracy of the roller shape. The mature processing technology and strict quality inspection process make all the roller outer rings radial runout and the working surface roundness is good, so that the guide system has extremely error during operation. Small, stable operation, and extremely low operating noise.
