- Steel coil clamping mechanisms
- Plastic injection molding ejectors
- Paper roll positioning systems
- Shipbuilding fixture actuators
Installation note:
Align within 0.2mm angular tolerance during mounting. Use flexible couplings
for stroke-end shock absorption. Pre-lubricate through air ports before initial
operation. Max side load: 15% of rated thrust.
