- Plastic injection molding ejectors
- Automated conveyor gate actuators
- CNC machine tool clamping devices
- Pharmaceutical blister packaging machines
Installation note:
For vertical mounting, reduce maximum load capacity by 30%. Lubricate through air port using ISO VG32 hydraulic oil
if operating below 0.3 MPa. Maintain 0.5mm minimum clearance between magnetic sensor and cylinder body.
