Heavy-duty locking cylinder featuring fail-safe mechanical position retention. The dual-chamber locking mechanism prevents accidental movement during power loss. Precision ground rod (h7 tolerance) with multi-lip seals ensures ≤0.01mm/min creep when locked. Requires 5-40μm filtered air with ISO VG32-grade lubrication.
- Vertical load holding in automated assembly lines
- Safety braking for material handling elevators
- Position retention in CNC tool changers
- Emergency stop systems for automotive fixtures
- Press machine mid-stroke holding operations
Installation protocol:
Maintain ≤0.2mm/m alignment tolerance during mounting.
Lubricate lock pins with silicone grease (Molykote EM-50L recommended)
every 5,000 cycles. Never exceed 90% of max locking force for safety.
