Heavy-duty locking cylinder featuring fail-safe position retention with 3,500N static holding force. The chrome-plated piston rod (hardness HRC45-50) and aluminum alloy body ensure corrosion resistance in humid environments. Requires 40μm filtered air and ISO VG32 hydraulic oil lubrication (when used with locking function).
- Vertical load braking in automated assembly lines
- Safety positioning in press machine tooling
- Emergency stop mechanisms for material handling
- Overhead clamping systems in CNC machining
- Position retention in unstable pneumatic pressure conditions
Operation note:
Engage lock only when cylinder is fully extended/retracted. Lubricate wedge mechanism every 500,000 cycles using specified grease (AirTAC LG-100). Maintain 0.3MPa minimum pressure for reliable unlocking.
