Industrial Hydraulic Cylinder Repair
Heavy-duty, large bore and high-pressure hydraulic cylinders rebuilt in our shop — honing, chrome rod replacement, resealing, piston and gland repair — backed by a 24-month warranty.
Industrial hydraulic cylinder repair & rebuilding
A leaking, drifting or scored cylinder is a machine that cannot hold its load — and a new large-bore or mill-duty cylinder can cost a fortune and take weeks to arrive. We repair and rebuild industrial hydraulic cylinders in our Rialto, CA shop: teardown, inspection, honing, chrome rod replacement, resealing, and piston and gland repair, all backed by a 24-month warranty. From standard tie rod cylinders to large-bore forging press and steel mill cylinders, we rebuild them to hold pressure and hold position.
Heavy-Duty & Large Bore Cylinders
Large bore, high pressure, mill duty and forging press cylinders — the expensive units where rebuilding beats buying new on cost and lead time.

Industrial & heavy-duty cylinders
General industrial and heavy-duty cylinders for presses, material handling, construction and manufacturing equipment.
Large bore & high pressure cylinders
Large bore, high pressure cylinders where honing, rod work and seal selection all have to be right for the cylinder to hold rated pressure.
Forging press & steel mill cylinders
Forging press and steel mill cylinders — large, hot, contaminated service. Full rebuilds including barrel honing, rod replacement and gland work.
Mining equipment cylinders
Cylinders from mining and heavy earthmoving equipment, rebuilt to survive dust, shock loading and abrasive service.
Hydraulic press cylinder rebuilding
Press cylinders rebuilt to hold position under load — no drift, no creep, no weeping past the seals.
Tie rod, welded & telescopic cylinders
Tie rod cylinders, welded cylinders and multi-stage telescopic cylinders — each with its own seal, wear-band and alignment requirements.
Mill duty cylinders
Mill duty cylinders built for continuous, high-cycle service in steel and processing plants, rebuilt to mill tolerances.
Custom manufacturing
Custom cylinders manufactured to your bore, stroke, mounting and port specifications when repair is not practical or no OEM unit is available.
How we rebuild a cylinder
- Rod repair & chrome rod replacement: scored, bent or pitted rods are straightened, re-chromed or replaced — a damaged rod will destroy new seals, so it is fixed first.
- Honing: cylinder barrels are honed to restore a true, smooth bore that seals properly and does not wear out new piston seals.
- Resealing: complete seal kits — piston seals, rod seals, wipers and wear bands — matched to the pressure, temperature and fluid in your system.
- Piston and gland repair: pistons, glands, caps and ports inspected and repaired or replaced; threads, bores and seal grooves restored to specification.
- Tested before return: pressure and function checks so the cylinder holds load and holds position when it goes back into service.
Brands we have repair experience with
We have repair experience with major cylinder brands including Parker, Bosch Rexroth, Eaton, Enerpac and HYDAC — hands-on rebuilding experience with their designs, not authorized affiliation; we never claim to be an authorized service center for any manufacturer. See our brands page. We also repair the pumps and valves that drive these cylinders — see hydraulic pump repair and forging press hydraulic repair — and the gearboxes behind the equipment, at gearbox repair. Turnaround depends on equipment condition, required parts, job complexity and availability. Call (714) 204-5167 or request a quote; we serve customers all over the United States with emergency pickup & delivery to our shop.
How a rebuild works
Every pump or cylinder that comes into our Rialto, CA shop is disassembled, cleaned and inspected before we quote. We measure wear, check clearances against the manufacturer’s tolerances, identify the failed parts, and give you a straight answer: rebuild it, repair the failed section, or replace it. Turnaround depends on equipment condition, required parts, job complexity and availability. All rebuilds are backed by our 24-month warranty.
