Trunnion Mount Cylinders

Our trunnion mount cylinders not only offer a mounting style allowing for increased capacity in the dump body through a significant reduction or elimination of the dog house, but also many other features. Offered in both three and four stage versions, the trunnion mount features strict machining tolerances, solid stop contact faces* and larger overlap between stages, making our cylinders some of the strongest and most stable cylinders on the market. 

  • Self-bleeding design for easier installation process
  • No packing or head nuts on each stage. Only one head nut that doesn’t need adjustments
  • Chrome-plated final stage extends the life of the cylinder
  • Solid stops machined into top and bottom of each stage, eliminating stop rings and threaded stops
  • Stages are machined and precision ground inside and out to allow for optimal seal / wiper performance
  • Each cylinder is equipped with bearing supports at both the top and bottom. Longer stages have increased overlap for improved column stability.
  • Tight machining tolerances cause smaller tube clearances that result in increased rigidity
  • One of the lightest cylinders on the market which translates to greater payloads, less oil consumption and faster dumping
  • Low maintenance requirements offer many years of top performance without additional expenses
  • Easily remove outer cover for ease of service

QUALITY MATERIALS

  • All steel tubing are made from seamless hot rolled steel, this results in higher tensile tubes for increased column strength and stiffness*
  • Stages have no welded seems allowing for higher pressure capabilities
  • The quality steel used increases resistance to mechanical stress and increases cylinder life
  • Seals and wipers are made of polyurethane and feature a double lip design assuring optimum performance in all climate conditions (-40°F to 212°F / -40°C to 100°C)
  • Bearing supports are made of DELRIN®, they are compatible with all types of hydraulic oils approved by pump makers and are
