Your hydraulic cylinder will be disassembled and inspected from end to end. Critical dimensions will be measured and all component condition will be evaluated to bring your cylinder back to peak performance. A complete estimate will be provided for approval prior to commencing any repairs.

Glands and pistons can deteriorate over time, especially in harsh working conditions. Glands and pistons can be modified for improved sealing performance or replaced to ensure correct clearance and maximize cylinder operation.

Seals can deteriorate over time and from extreme working conditions. Cylinder cycles, fluid temperature, fluid condition and the condition of cylinder components can all contribute to seal failure. Cylinders do not usually fail from this cause, however this is the usual symptom of the problem.

Cylinders usually require mounting. Some styles incorporate threads, pins, trunions, tabs, bolts, bearings or bushings as an example to attach the cylinder to the mechanism that they are operating. Failure of any of these devices can stop operation of the cylinder.

Any deterioration to Surface finish or Dimensional Clearances will cause Internal Oil Leakage & the cylinder may not function at full efficiency. Most cylinder bores are honed to Ra8 to Ra16 Micro finish & a .1mm or .004 inch diameter tolerance. All honing is done in house.

All cylinders require flanges, couplings, & fittings as a method of receiving oil flow from the control system. Failure of these items will cause failure of the component.

Any deterioration of the finish or straightness will cause seal failure & external oil leakage. Damaged cylinder rods and stages can be polished and/or hard chrome plated in house.
