LFR Series U Groove Bearing Yoke Type Track Roller Linear Motion Bearing

LFR series U groove yoke type track roller linear motion bearings are premium linear transmission components specially designed for cylindrical tracks, featuring internal double row angular contact ball bearing structure and thick-walled outer ring to deliver excellent high load capacity.

Adopted advanced Gothic arch outer ring profile, they form dual 60° contact points with tracks, ensuring ultra-low friction resistance, high allowable speed, stable load distribution and long service life, effectively avoiding stress concentration and edge effect.

Equipped with KDD metal shield or NPP rubber seal for reliable dust prevention, these rollers support optional concentric/eccentric pivot for easy installation and preload adjustment, and corrosion-resistant stainless steel material is available for special working conditions.

With superior radial runout accuracy and smooth working surface, they realize ultra-quiet, high-precision and stable operation, ideal for various linear motion transmission systems in industrial machinery, automation equipment and precision devices.
