High-precision locking cylinder featuring dual-piston mechanical brake system for position retention under load. The SULB series combines standard cylinder functionality with instantaneous position locking capability, maintaining stability even during power/pneumatic failure. Integrated wear compensation ensures consistent locking force through 500,000+ cycles.
- Vertical load holding in automated assembly lines
- Emergency stop position locking in CNC machinery
- Intermediate position fixation in material handling systems
- Safety braking for overhead lifting equipment
- Precision alignment jigs in semiconductor manufacturing
Installation note:
Requires separate 4mm air line for lock release function (0.3-0.7 MPa).
Lubricate with ISO VG32 hydraulic oil. Avoid side-load forces exceeding 50N.
Perform lock mechanism inspection every 10,000 cycles.
