Heavy-duty locking cylinder with instant position-holding capability, featuring dual safety mechanisms: spring-applied brake releases only when air pressure exceeds 0.15MPa. The double-sealed brake unit prevents accidental movement during power loss. Includes wear-resistant guide bands for precise alignment and magnetic piston for position sensing compatibility.
- Vertical load holding in material handling systems
- Emergency stop positioning in CNC machinery
- Pallet clamping in automated warehouses
- Overhead lifting equipment safety brakes
- Press machine tooling position locks
Installation guidelines:
Requires minimum 5μm filtered air with lubrication (ISO VG32 recommended).
Locking function works only in fully extended position - ensure proper stroke adjustment.
Allow 50mm clearance behind cylinder for maintenance access.
Critical note:
Brake shoes require inspection every 500,000 cycles.
Never use silicone-based lubricants with NBR seals.
Maximum side load: 15% of piston thrust capacity.
