Heavy-duty locking cylinder featuring dual safety mechanisms: pneumatic unlock (requires 0.3MPa minimum pressure) and automatic mechanical engagement during power loss. The chromium-plated piston rod (HRC 45-50 hardness) withstands side loads up to 150N. Requires ISO VG32 hydraulic oil for buffer adjustment.
- Press brake tooling position locking
- Vertical elevator emergency stop systems
- Automated welding fixture stabilization
- Die-casting machine safety interlocks
- Material handling mid-stroke pause operations
Installation guidelines:
Maintain ≤0.5mm/m alignment tolerance during mounting. Apply Molykote 111 paste
to piston rod before operation. Locking force requires 0.5MPa minimum air supply
for disengagement. Annual lubrication of lock pins recommended.
