Hydraulic Cylinder Services
HydraPro repairs and overhauls hydraulic and pneumatic cylinders of all makes, sizes, and types. Whether the issue is a simple seal failure or extensive rod and barrel damage, our workshop handles the full repair process — restoring your cylinder to operational condition and testing it before it goes back into service.
Cylinder Inspection & Diagnosis
Every repair begins with a thorough inspection. Cylinders are assessed for rod scoring and chrome condition, barrel wear and honing, seal failure, bent or damaged rods, corrosion, and structural damage. A diagnosis report is provided before any work proceeds, ensuring transparent, accurate recommendations.
Disassembly, Repair & Reassembly
Cylinders are fully disassembled in our workshop, with each component cleaned, measured, and evaluated. Repairs are carried out to original specifications, with all components reassembled to the correct torque settings and alignment tolerances.
Seal Replacement & Seal Kit Installation
Rod seals, piston seals, wiper seals, and O-rings are replaced with new components matched to the cylinder's operating pressure, fluid type, and temperature range. HydraPro maintains an extensive inventory of seal kits for common cylinder types, with custom seals available for non-standard sizes.
Rod Repair, Re-Chroming & Polishing
Damaged piston rods are repaired through grinding, chrome stripping, re-chroming, and precision polishing to restore the original surface hardness, finish, and dimensional tolerances. Minor surface defects can often be resolved through polishing alone. Severely damaged rods are replaced with new chrome rod stock machined to specification.
Cylinder Honing & Barrel Repair
Cylinder barrels with internal scoring, pitting, or wear are honed to restore bore roundness and surface finish. Honing is carried out to remove damage while keeping the bore within seal compatibility tolerances — extending the life of both barrel and seals.
Leak Detection & Repair
Internal and external leaks are diagnosed and resolved as part of every repair. Root causes — including worn seals, rod damage, loose fittings, and cracked welds — are identified and corrected rather than simply patched.
Pressure & Performance Testing
Every repaired cylinder is pressure tested on our test bench before delivery, verifying integrity at operating pressure. Test documentation is provided on request.
Preventive Maintenance & Servicing
HydraPro offers scheduled cylinder servicing to extend service life and prevent unplanned failures. Planned maintenance intervals, seal condition checks, and rod inspections help avoid costly breakdowns before they occur.
