- Plastic injection molding machine core-pull mechanisms
- Precision paper cutting/crimping machines
- Semiconductor wafer handling robots
Installation Tip:
For vertical installations exceeding 45° angle, use the auxiliary support bracket (SAI-SB63)
to prevent side load. Lubricate through the built-in grease nipple (SAI-LK3 compatible)
every 3,000km of cumulative stroke movement.
