NSKTAC C High-Rigidity Ball Screw Support Bearings

NSKTAC C support bearings for ball screw drives are designed to deliver utmost fatigue life and performance capacity in modern machine tool feeding systems. They’re designed to withstand large axial forces while providing rigid and accurate ball screw support. Available as open bearings or sealed for contamination resistance and considerably longer grease life.
