Hydraulic Cylinder Repair: Precision & Manufacturing for Unstoppable Performance

Expert hydraulic cylinder repairs that restore peak efficiency

Hydraulic cylinders are the backbone of many industrial and mobile applications, converting fluid power into linear motion. When they fail, production comes to a standstill.

At K&R Hydraulics we know how important these components are which is why we have dedicated our expertise and invested in world class facilities to provide hydraulic cylinder repair, refurbishment and manufacturing services. Our reputation and experience in the hydraulic cylinder repair industry makes us a trusted partner for businesses across the industrial sector.

End‑to‑End Capability
Trusted Reputation
Safety & Compliance

With over 38 years of experience our highly skilled and dedicated team can handle any job, from routine reseals to complex structural repairs and full cylinder manufacture. We don’t just fix cylinders, we restore them to “as new” performance, and we upgrade components to outlast previous failures and ensure long term reliability. We work with a diverse range of clients, we tailor our hydraulic and pneumatic cylinder solutions to meet client needs, whether it’s repair or custom manufacturing.

Our Hydraulic Cylinder Services

K&R Hydraulics offers a full range of services, backed by state of the art equipment and technical knowledge:

Whether it’s a minor reseal or full overhaul our team can handle all types and sizes of hydraulic cylinders. We diagnose the root cause of failure and don’t just repair but upgrade components where possible to enhance future performance and durability. During disassembly we remove and inspect all components. We replace worn components such as pistons and glands as required to maintain optimal performance. We know how important downtime and time to repair is so we focus on efficient service to keep our clients operations running smoothly.

We are leaders in high precision hydraulic cylinder barrel honing. Our Sunnen honing machine with rotary brush cleaner and refrigerated fine filtration is second to none. We have a range of dimensional and surface measuring equipment to ensure finished honed surfaces are within seal manufacturer’s specifications, critical for sealing and longevity.

We can design and build new hydraulic cylinders from scratch or fabricate individual components such as rods, barrels, glands and pistons to meet specific requirements. This includes one off and highly bespoke solutions for unique applications.

Our workshop has the latest machinery including an Automatic Bore Welder and Sub-Arc Welder with rotator functionality for robust and precise welding of cylinder components. Our new Kiheung Rigitrax 8M CNC Mill (X axis travel 8M Y axis travel 1.5M& Z axis travel 2M, Universal auto positioning head, inbuilt turning table & 4th axis rotary table) &10M Geminis CNC Lathe (10 metres between centres, 525mm spindle bore and full CNC functionality) can machine even the largest cylinder components with precision and speed.

We are large excavator cylinder specialists and excel in diagnosing complex failures. Through in-house failure analysis and detailed reporting we specialise in identifying design flaws in hydraulic equipment. We then implement precise modifications during repair or manufacture to extend the life of hydraulic components and reduce total cost of ownership.

Every repaired or manufactured cylinder is tested on our hydraulic cylinder test equipment with live hydraulic fluid condition monitoring and data logging. We use calibrated equipment to torque piston nuts to OEM specifications. After testing and priming we paint as a final step before packaging and shipping. This ensures optimal functionality, leak free operation and validated performance before the cylinder leaves our facility.
