Industrial-grade locking cylinder featuring instant position retention through spring-engaged mechanical brake. The dual-piston lock mechanism activates automatically upon pressure loss, preventing unintended movement. Precision honed tube (Ra≤0.2μm) ensures smooth operation with ≤0.05mm piston rod runout. Requires 5-40μm filtered air with oil mist lubrication (ISO VG32 recommended).
- Vertical load holding in automated assembly lines
- Emergency stop positioning in material handling systems
- Tooling fixture stabilization during CNC machining
- Safety interlocks in press brake machinery
- Elevator door locking mechanisms
Installation note:
Lock engagement requires minimum 0.3MPa air pressure. For vertical applications,
install with lock facing downward to prevent debris accumulation.
Lubricate guide bushings every 500km stroke operation.
