Heavy-duty locking cylinder with fail-safe position retention, featuring dual-stage locking mechanism that engages automatically during power loss or pressure drop. The integrated shock absorber minimizes end-impact vibration, while the chrome-plated rod resists scoring in high-cycle applications. Requires 5-40μm filtered air with ISO VG32 lubricant (optional oil-free operation).
- Vertical lifting systems in automated warehouses
- Press brake tooling position locking
- Overhead conveyor emergency stop mechanisms
- Robotic welding fixture clamping
- Die casting machine safety interlocks
Installation protocol:
Maintain ≤0.5mm alignment tolerance during mounting. Perform lock mechanism
lubrication every 50,000 cycles using MIL-PRF-6085 grease. Avoid lateral
forces exceeding 150N on locked piston rod.
Critical note:
Lock disengagement requires minimum 0.3MPa working pressure. Never
exceed 1.2MPa during manual override operations.
