High-rigidity industrial cylinder featuring wear-compensation seals and anti-rotation piston rod. The anodized barrel resists chemical corrosion and minimizes internal scoring. Designed for medium-duty cycles (up to 5 million strokes) with 0.5mm rod runout tolerance. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Automated assembly line clamping mechanisms
- Plastic injection molding ejector systems
- CNC machine tool door actuators
- Food processing conveyor gate controls
- Automotive welding fixture positioning
Installation notes:
- Align cylinder axis within 0.2° angular misalignment tolerance
- Maintain 1.5× bore diameter clearance for rod extension space
- Use copper-free anti-seize compound on rod threads
- Install air filter-regulator-lubricator (FRL) unit upstream
