High-torque industrial cylinder engineered for heavy-duty linear motion applications. Features chrome-plated piston rod (HCF hardness 60-65) with multi-lip seal configuration for extended service life. The aluminum alloy end caps incorporate vibration-damping mounting surfaces, while the anodized barrel ensures corrosion resistance in humid environments. Requires ISO VG32 hydraulic oil mist lubrication for optimal performance.
- Press machine ejection systems (200-300 ton capacity)
- Automotive welding fixture positioning
- Foundry mold clamping mechanisms
- Bulk material gate valve actuation
- Shipbuilding plate bending equipment
Installation protocol:
Align cylinder axis within 0.2mm perpendicular tolerance. Use flexible couplings
when connecting to guided mechanisms. Perform 50 break-in cycles at 2 bar
pressure before full-load operation. Requires 5μm filtration with automatic drain.
