- Medical device clamping mechanisms
- Packaging machine ejector systems
- Semiconductor wafer positioning stages
- Cleanroom automation (low particle generation design)
Installation tip:
When adjusting stroke length, ensure locking screws are torqued to 0.8N·m maximum.
Use thread locker (medium strength) on adjustment bolts for vibration-prone environments.
Allow 5mm clearance around adjustment mechanism for maintenance access.
