- Glass handling equipment requiring precise positioning
- Automated welding jigs with adjustable clamping force
- Packaging line product height compensation mechanisms
- Die casting machine core pull operations
Installation protocol:
Always engage alignment pins during mounting to prevent rotational torque damage.
For stroke adjustment:
1) Loosen lock nut (17mm wrench size)
2) Rotate stopper collar (each mark = 0.5mm adjustment)
3) Re-tighten to 35-40N·m torque.
Maintain 0.3mm minimum lubrication film on rod surface.
