• LFR series guide roller bearing is the most widely used and economical product among the linear guide rollers. It Can be applied to circular guides, with stable operation, small error, extremely low operating noise and high operating speed. The contact between the roller and the guide rail is 60 degrees at two points, which has good contact performance and very little operation, so as to achieve a longer replacement.
• The roller adopts the internal structure design of the double row angular contact ball bearing and the thickened outer ring, so that the roller has a higher bearing capacity. The roller bearing is equipped with an eccentric wheel and a concentric shaft and is easy to install.
• The rollers are made of high-quality bearing steel, heat-treated, precision-ground and shaped, and filled with high-quality multi-purpose grease for long life. Roller dustproof adopts metal dustproof cover (KDD) or rubber seal ring (NPP).
