LR Series Stainless Steel Ball Bearings

LFR series guide roller bearing is the most widely used linear guide roller, economic and practical products, can be adapted to cylindrical guide, smooth operation, small error, running noise is very low, running speed is very high.

Auto Tensioner Bearing​ Advantage

• The contact between the roller and the guide rail is 60 ° at two points, which has good contact performance and low running resistance, thus achieving a long service life.
• The roller adopts double row angular contact ball bearing internal structure design and thickened outer ring, so that the roller has a higher bearing capacity, the installation is simple after roller bearing is configurated with eccentric wheel and concentric shaft .
• The roller is made of high-quality bearing steel or stainless steel, processed by heat treatment and precision grinding, and filled with high-quality multi-purpose grease with long life.Roller dust protection with metal dust cover (KDD) or rubber seal ring (NPP).
• In addition to the standard production of rolling bearing, the LR series supporting roller with stable operation and small error adopts special processing technology to adapt to the special working mode of inner ring fixation and outer ring rotation

If there is a tilt angle between the inner and outer rings of the bearing, the life of the bearing will be reduced, and the running accuracy of the bearing will be also reduced ,but the running noise will be increased.

Double row angular contact ball bearings generally use nylon cage or brass solid cage.

Attention should be paid to the installation of double-row angular contact ball bearing. Although the bearing can bear two-way axial load, if there is a ball loading gap on one side, it should be noted that the main axial load should not pass through the groove side with a gap.When the bearing is used, it should be noted that the raceway on one side without the gap of ball loading should bear the main load.
