A heavy-duty locking cylinder featuring dual safety mechanisms: pneumatic holding during operation and mechanical locking during power loss. The hardened steel lock pin engages automatically when pressure drops below 0.15 MPa, preventing unintended movement. Precision honed tube ensures ≤0.05mm bore tolerance for smooth operation.
- Vertical load holding in automated assembly lines
- Safety positioning in injection molding machines
- Emergency stop systems for material handling equipment
- Overhead lifting devices requiring fail-safe brakes
- Press machine tooling with mid-stroke position lock
Installation note:
Lubricate lock mechanism with ISO VG32 hydraulic oil during maintenance.
Ensure alignment tolerance <0.2mm/meter to prevent side load. Lock releases
automatically upon air pressure restoration (≥0.3 MPa).
