Heavy-duty locking cylinder featuring fail-safe mechanical braking for vertical load holding. The dual-piston design ensures stable mid-stroke locking with ±0.5mm repeatability. Anodized aluminum barrel with corrosion-resistant coating makes it suitable for harsh environments. Requires 5-40μm filtered lubricated air (ISO 8573-1 class 3).
- Vertical lifting systems in automotive assembly lines
- Position retention in CNC tool changers
- Safety brakes for material handling robots
- Press machine safety interlocks
- Elevator emergency stop mechanisms
Installation note:
Locking engagement requires minimum 0.3MPa air pressure. For vertical use,
maintain 1.5× stroke length clearance below piston head. Lubricate with ISO VG32
hydraulic oil if non-lubricated air is used.
Critical maintenance:
Replace brake pads every 500,000 cycles under full load conditions.
Never disengage locking mechanism during system pressurization.
