Heavy-duty locking cylinder featuring fail-safe position retention with dual safety mechanisms. The integrated mechanical lock engages automatically during power/pneumatic failure, making it ideal for vertical applications requiring position stability. Enhanced chromium-plated piston rod resists side loads up to 30% of maximum thrust.
- Vertical lift systems in material handling
- Safety locking in press brake machines
- Position holding in automated welding fixtures
- Emergency stop mechanisms for overhead conveyors
- Precision alignment in semiconductor manufacturing
Installation note:
Requires minimum 0.3MPa unlocking pressure. Lubricate with ISO VG32 hydraulic oil
before initial use. Locking direction must align with gravitational forces in vertical
installations. Allow 50mm clearance for rod extension during maintenance.
Critical parameters:
Maximum side load 150N. Do not exceed 1,000mm/s piston speed.
Use air dryer when humidity exceeds 70% RH to prevent lock mechanism corrosion.
