Product Details

Custom Through-Rod Hydraulic Cylinder with Center Trunnion Mounting

APEX CDRC Series | Double-Acting | Balanced-Area Design

This custom double-rod hydraulic cylinder features a center trunnion mounting style, making it suitable for oscillating and linkage-driven machinery. The through-rod design provides equal effective areas on both sides, delivering equal force and speed in both directions, which simplifies symmetric hydraulic circuit design. Bore diameters range from 32 to 250 mm, strokes from 25 to 3000 mm, and working pressures up to 250 bar (350 bar max design pressure for special configurations).

Key Selling Points

  • Symmetric motion: Equal effective areas, force, and speed in both directions when rod diameters are identical, enabling precise reciprocating movements.
  • Center trunnion mounting: Ideal for oscillating and pivot-based machinery, reducing side loading and improving alignment.
  • Customizable stroke and ports: Stroke lengths from 25 to 3000 mm and port positions and sizes tailored to your piping and equipment clearance.
  • Optional position sensing: Integrate proximity switches, magnetic sensors, or linear transducers for automated control and stroke monitoring.
  • Robust construction: Precision-honed seamless steel barrel, hard-chrome-plated piston rods, and polyurethane/PTFE seals for durability.
  • CE certified options: Available with EN ISO 12100 and ISO 6020-1 compliance for EU machinery.
