Heavy-duty locking cylinder with integrated position retention capability, featuring dual safety mechanisms (pneumatic + mechanical). The tungsten-coated piston rod and triple-lip seal design ensure over 3,000km service life under standard conditions. Requires 5-40μm filtered lubricated air (ISO8573-1 class 4).
- Vertical lifting systems requiring position hold (e.g., elevator safety brakes)
- Automated welding fixture positioning
- Press machine intermediate stroke locking
- Overhead material handling emergency stop systems
- Automotive assembly line pallet stops
Installation protocol:
Must maintain ≤0.5mm alignment tolerance during mounting.
Locking function activates only when pressure ≥0.3MPa.
Requires monthly lubrication (ISO VG32 equivalent oil).
Critical note:
Do NOT use as primary safety brake in vertical applications -
always install secondary mechanical safety device.
Locking mechanism requires manual release during maintenance.
