A precision-ground polyurethane spindle liner that supports bar stock inside the lathe spindle bore during bar feed operation, eliminating vibration, reducing noise, and protecting spindle bearings from radial loads generated by off-center or slightly bent bar material.
- Split design for tool-free installation
- Engineered to match standard spindle bore diameters
- Rated for bar feed speeds up to 5,000 RPM
- Critical for achieving tight tolerances and superior surface finish in high-production CNC turning
Quiet the spindle. Protect the bearings. Hit your tolerances.
