Quiet Operation
Circulating balls deliver smooth reciprocating motion, reducing metal friction noise and keeping operation quiet at high speed.
Precise Tolerance
Strict dimensional tolerance control gives excellent bore accuracy, uniform clearance with the guide shaft and high positioning precision.
Low-Friction Travel
A closed ball-circulation structure keeps rolling friction low, making reciprocating motion light and responsive with less drive loss.
