Description:
LR series guide roller with cylindrical outer circle or crown outer circle
LR series bearing support roller bearing system has the following characteristics:
• The outer circle of the product is processed as an arc surface of the R500 (model suffix with U), so that the product can bear good stress in the process of use.
• The roller adopts deep groove ball bearing or double row angular contact ball bearing internal structure design and extra thick outer ring, so that the roller has higher carrying capacity.
• The roller is made of high quality bearing steel, which is processed by heat treatment and precision grinding and is filled with high quality and multi-purpose oil with long life.Roller dustproof uses metal dust cover or rubber seal ring.

Advantages:
1. Small resistance, long life and wide application
With the support roller of the R500 circular arc, the force between the roller and the guide rail is even, avoiding the stress concentration, friction resistance is small, and the working life of the product is improved a lot.Most of the double-row support roller can be lubricated through grease holes in the inner ring to meet the poor working conditions.

2. Easy to install
With eccentric shaft and concentric shaft of roller bearing, it is convenient to install and adjust the eccentricity of eccentric roller to get the proper preload.
