- Variable height positioning in assembly automation
- Material feeding systems with adjustable stroke requirements
- Packaging machinery for product height compensation
- Test equipment requiring repeatable force application
Operational guidance:
Lubricate with ISO VG32 hydraulic oil before initial use.
For fine adjustment: Loosen lock nut, rotate adjustment screw (1 full rotation = 1.25mm stroke change),
then re-tighten to 2.5N·m torque. Avoid over-compression beyond marked stroke limits.
