- Plastic injection molding machine ejectors
- Conveyor system gate actuators
- Warehouse vertical lift positioning systems
Installation note:
Lubricate with ISO VG32 hydraulic oil before initial use.
Maintain 0.3-1.0 MPa operating pressure for optimal seal performance.
Allow 5mm minimum clearance around cylinder body for heat dissipation.
