High-precision locking cylinder designed for position retention under load. Features triple sealing protection and chromium-plated piston rod (HRC 45-50 hardness). The mechanical lock engages automatically at stroke ends and requires 0.3-0.6MPa control air for release. Includes magnetic piston for position sensing compatibility.
- Vertical load holding in automated assembly lines
- Emergency stop positioning in material handling systems
- Press machine safety interlocks
- Robotic welding fixture clamping
- Overhead crane brake systems
1. Lubricate with ISO VG32 hydraulic oil before initial use
2. Maintain 0.5mm minimum clearance between lock mechanism and mounting surface
3. Lock release pressure must NOT exceed 0.6MPa to prevent seal damage
4. Use with 5μm filtered air to extend service life
