Track roller bearing
Guide Way Ball Bearing
1. Series LFR rollers are the most widely-use and economy product among the linear motion track rollers, and they can suit to the cylindrical track.
2. There are two contact points between the roller and track, so the contact function is favorable.
3. Rollers feature double row angular contact ball bearing in its internal structure design and a thick-walled outer ring, so rollers can accommodate higher loads.
