High-precision locking cylinder with fail-safe mechanical brake mechanism, designed for vertical applications requiring position retention during power/pressure loss. Features triple sealing structure with wear-resistant guide bands and integrated magnetic sensor slots (sensors optional). Requires 40μm filtered air with ISO VG32-grade lubricant.
- Vertical lifting mechanisms in assembly lines
- Safety positioning in press brake machines
- Workpiece clamping in CNC machining centers
- Emergency stop systems for material handling
- Semiconductor equipment requiring vibration-free holds
Installation note:
Locking function activates automatically at stroke ends. For mid-stroke locking,
specify "-SM" variant. Maintain 0.3 MPa minimum pressure for reliable unlocking.
Lubricate piston rod weekly in high-cycle applications.
Critical notice:
Never apply external force to release locked piston - use manual release valve.
Avoid lateral loads exceeding 50N. Align cylinder within ±1° angular tolerance.
