- Precision clamping mechanisms in CNC fixtures
- Cartesian coordinate actuator systems
- Medical device positioning stages
- Semiconductor wafer processing equipment
Installation guidance:
Maintain parallel alignment during mounting using the integrated leveling surfaces.
For vertical installations, ensure rod-end-down orientation to prevent condensate accumulation.
Allow minimum 3mm clearance around cylinder body for heat dissipation.
