Industrial-grade locking cylinder featuring fail-safe position retention through mechanical interlock. The integrated locking mechanism engages automatically at stroke end, requiring 0.3-0.6MPa release pressure for disengagement. Precision honed tube ensures ≤0.05mm bore roundness for consistent performance. Includes wear-resistant scraper seal for particle protection.
- Vertical load holding in robotic welding arms
- Safety positioning in press brake tooling
- Intermediate stop control in assembly line conveyors
- Workpiece clamping during CNC machining
- Elevation locking in material handling platforms
Installation note:
Lubricate piston rod with ISO VG32 hydraulic oil before initial use.
Maintain 0.5MPa minimum pressure during lock release.
Avoid side load exceeding 30N on rod end.
