Lr Series Ball Bearing
The outer circle of LR series bearings is machined into an R500 arc surface (type suffix with U), which makes the products bear good force in use. The roller adopts deep groove ball bearing or double row angular contact ball bearing internal structure design and thickened outer ring, so that the roller has a higher bearing capacity. The rollers are made of high quality bearing steel, processed by heat treatment and precision grinding, and filled with high quality multi-purpose grease with long life. Dust-proof roller adopts metal dust-proof cover or rubber sealing ring. The supporting roller with R500 arc surface has uniform force between the roller and the guide rail, avoiding stress concentration and small friction resistance, so that the working life of the product is improved a lot. Most double row support rollers can also be repeated through the grease hole on the inner ring, to adapt to the harsh working environment.
