Ceramic/NewSurf®
- Manufactured from high-tech ceramic
- Offers one of the lowest friction coefficients on the market
- Suitable for medical implants
- Specifically designed for titanium, stainless steel, & other difficult materials
- Suitable for the tightest production tolerances
- Available in round profile only
Bronze
- Uniquely designed with steel body and bronze insert for durability
- Most cost-effective material to prevent marking on the workpiece
- Best suited for non-medical parts production
- Suitable for clamping workpiece material up to h8 tolerance
- Suitable for all non-copper materials
