Structural Design Features
Clearance Fit Design: Precision clearance fits are employed between the housing inner wall and balls, as well as between balls and guide rails. This ensures smooth motion while compensating for minor installation errors through the clearance.
Extended Guide Section: The elongated housing design increases the contact length between the bearing and guide rail. This effectively distributes loads during long-stroke movements, enhances the overall structure's resistance to deformation, and maintains motion precision.
