SLA: HIWIN SLA are ready-to-install floating-end (supported-end) ballscrew bearing units, designed to pair with the SFA fixed-end unit. Absorbing radial forces while accommodating axial movement of the ballscrew shaft, SLA units prevent binding caused by thermal expansion during operation. Axis height is matched to the HIWIN SFA series for seamless pairing. Compatible with HIWIN ballscrews for a complete linear motion solution.
