Heavy-duty locking cylinder featuring fail-safe position retention through spring-engaged mechanical brake. The dual piston design ensures 3,500N locking force (at 0.5MPa) with automatic re-engagement during pressure loss. Requires 5-40μm filtered air and ISO VG32 hydraulic oil lubrication for optimal performance.
- Vertical load holding in material handling systems
- Emergency stop positioning in injection molding machines
- Safety clamping in CNC fixture setups
- Overhead conveyor pause mechanisms
- Robotic arm position memory during power outages
Installation criticals:
Lock engagement requires minimum 0.3MPa air pressure. Always install with 1°-2° downward tilt for optimal lubrication drainage.
Maintain 50mm clearance around lock mechanism for thermal expansion.
- Apply 0.15-0.8MPa air pressure to release port (L port)
- Actuate cylinder through normal pneumatic control
- Cut air supply to engage automatic mechanical lock
- Reapply pressure for 0.5s minimum before next movement
