A heavy-duty locking cylinder designed for position retention during power/pneumatic failures. Features chromium-plated piston rod with wear-resistant guide bands and dual anti-rotation design. The front-position mechanical lock engages automatically at stroke end or manually via external signal, providing up to 1,500N holding force.
- Intermediate stop mechanisms in automated production lines
- Safety position locking in press machinery
- Vertical load holding in material handling systems
- Precision fixturing for CNC machining centers
- Emergency brake systems in conveyor setups
Installation notes:
- Lock engagement requires minimum 0.3MPa residual pressure - install check valve in circuit
- For vertical mounting, use auxiliary support brackets for loads >50kg
- Allow 0.5mm lateral clearance during alignment to prevent binding
Engage lock by exhausting air from locking port (L1/L2). Release requires 0.15MPa minimum control pressure. For continuous locking, maintain pressure below 0.05MPa at exhaust port. Lubricate lock mechanism with ISO VG32 hydraulic oil monthly in high-cycle applications.
