Heavy-duty locking cylinder with fail-safe mechanical brake mechanism. Features dual-chamber lock design for instant position holding even during power loss. The chrome-plated piston rod (hardness HRC 45-50) and aluminum alloy barrel ensure durability in high-cycle applications. Requires air lubrication (ISO VG32 or equivalent).
- Vertical load holding in material handling systems
- Emergency stop mechanisms in press machines
- Position retention in automated welding fixtures
- Safety brakes in elevator test rigs
- Overhead clamping devices in CNC machining centers
Installation notes:
- Lock engages automatically at stroke end - ensure proper alignment with load direction
- Maintain 0.3-1.0MPa locking pressure during operation
- Lubricate through air supply (oil mist 1-2 drops/m³)
- Allow 15mm clearance around cylinder for heat dissipation
