Heavy-duty locking cylinder with fail-safe position retention capability. Features dual-stage cushioning and corrosion-resistant hard anodized aluminum construction. The integrated mechanical lock engages automatically upon pressure loss, making it ideal for vertical applications requiring position hold. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Vertical press machine safety brakes
- Automated welding fixture position locks
- Elevator emergency stop systems
- Material handling vertical axis stabilization
- Die-casting machine mold clamping
Installation note:
Lock mechanism requires 0.3MPa minimum working pressure for automatic engagement.
Perform monthly lock wedge lubrication using MIL-PRF-6085 grease. Avoid side-load exceeding 50N.
Critical maintenance:
Replace lock spring every 500,000 cycles or 2 years (whichever comes first).
Never disengage lock under load - use manual release valve for emergency unlocking.
