Linear drives

BALINIT C (WC/C) coating of ball screw drive balls increases service life and enhances dynamic.

BALINIT C (WC/C)-coated rollers and rails allow linear drives to operate under dry running conditions, e.g. in the semiconductor industry.

Advantages: higher dynamic operation possible under dry running conditions.
