Remanufacturing: Optimizing Existing Equipment

In addition to custom manufacturing, we offer dependable repair service for all makes of hydraulic cylinders and components. From a basic reseal and recertification to complete system analysis and rebuild, our complete in-house operation will minimize both equipment downtime and service cost.

We constantly seek opportunities to improve equipment performance and durability. Beyond part replacement, our re-engineering services can also modify an existing design for enhanced:

  • Performance (eg. cushions added for smooth operation)
  • Reliability (eg. thicker chromed surfaces for longer life)
  • Operator safety (eg. pilot operated check valve integration)

In addition, we can provide material upgrades and surface coatings to extend the life of your equipment. Sealing systems are commonly improved for longer component life or for use in extreme climates. Worn parts can often be salvaged and upgraded for better performance while reducing the overall repair cost.

When the demands of your equipment change, we are experienced in modifying hydraulic cylinders and components for different use. Common modifications include changing stroke length and conversion of a single acting cylinder to double acting.
