- Variable height adjustment in packaging machinery
- Position calibration fixtures for CNC tooling
- Material handling systems requiring variable stroke
- Pressure-sensitive clamping devices
Installation note:
Align stopper screws perpendicular to cylinder axis during adjustment.
Lubricate with ISO VG32 hydraulic oil monthly in high-cycle applications.
Allow 0.5mm clearance between stoppers at minimum stroke setting.
