High-precision locking cylinder with integrated mechanical brake system, designed for vertical load applications requiring position retention during pneumatic pressure loss. Features dual-chamber sealing technology and wear-resistant guide bands for smooth operation. Requires filtered air (5-50μm) with lubrication (ISO VG32 recommended).
- Vertical axis locking in CNC tool changers
- Workpiece clamping in semiconductor FOUP handling
- Safety brakes in automated material handling systems
- Position retention in robotic welding fixtures
- Emergency stop mechanisms in glass handling equipment
Installation note:
Brake engagement requires minimum 0.3MPa air pressure. For vertical mounting,
install with rod facing downward. Perform brake adjustment every 500,000 cycles
using built-in adjustment screw (torque limit: 0.5N·m).
