💡 Why use a yoke-type track roller without an inner ring in cam or guide systems?
It lets the raceway run directly on a hardened shaft while keeping rolling friction low.
- It saves space in compact linear guides
- It allows higher load capacity on properly hardened shafts
- It reduces friction in cam-driven or track-guided movements

This roller gives your rail or cam system steady tracking and clean motion with minimal effort.
