Industrial-grade dual rod cylinder engineered for heavy-duty applications requiring exceptional moment resistance and precise linear motion. Features twin chrome-plated piston rods with 4-point guided carriage that eliminates rotational movement, making it ideal for press-fitting operations and vertical Z-axis applications. The oversized guide blocks withstand 4× higher side loads compared to standard cylinders.
- Automotive welding fixture positioning systems
- Die-casting machine core-pulling mechanisms
- Paper converting equipment with precise web tension control
- Heavy pallet stacking robots in logistics centers
- Plastic injection molding machine ejectors
Installation guidelines:
Requires periodic relubrication every 500km stroke (use ISO VG32 hydraulic oil).
Avoid mounting in orientations where rods face downward to prevent particle accumulation.
Maintain 50mm minimum clearance around cylinder body for heat dissipation.
- Maximum side load capacity varies with stroke length - consult derating charts for >500mm strokes
- Requires 5-40μm filtration for optimal seal life
- For vertical applications: Add counterbalance valve when handling >150kg payloads
