Heavy-duty locking cylinder featuring fail-safe mechanical braking, designed for vertical applications requiring mid-stroke position retention. The wedge-lock mechanism engages automatically during pressure loss, preventing unintended movement. Hard chrome-plated rod with integrated scraper reduces contamination ingress. Requires 5-40 μm filtered air with ISO VG32 oil if lubricated.
- Vertical press tooling safety brakes
- Automated material handling position locks
- Injection molding machine core pull safety systems
- Elevator emergency stop mechanisms
- Robotic welding fixture position retention
Installation notes:
Lock engagement requires 0.3 MPa minimum air pressure for release.
Lubricate lock slider monthly with MIL-PRF-6085 grease.
Avoid side loads exceeding 50N on rod end.
Allow 15mm clearance around lock mechanism for heat dissipation.
