Bosch Rexroth Hydraulic Cylinder Repair in Fontana
Bosch Rexroth cylinders drive presses, injection machines, steel and plant equipment, and heavy mobile machinery where a drifting or leaking cylinder stops the whole line. Our Fontana cylinder bench rebuilds Rexroth cylinders in-house: complete teardown, honest measurement of bore, rod, piston and gland, and the machine work to return the cylinder to its working clearances before it is resealed and pressure-tested. No guesswork, no seal-only shortcut on a cylinder that needs metal work.

Tie-rod, welded and large-bore Rexroth cylinders
Each Rexroth construction is treated on its own terms. Tie-rod industrial cylinders are measured for barrel wear and rod condition and rebuilt with seals matched to pressure, fluid and duty. Welded cylinders from mobile equipment get bent or scored rods re-chromed or manufactured new on our own machines instead of straightened. Large-bore and mill-type work is checked for bell-mouthing, piston bypass and gland wear, then honed and renewed to the clearances the measurements call for.

Bosch Rexroth Hydraulic Cylinder Repair in Fontana · Fontana, CAQuoted from measurements, not from a catalogue
A Rexroth cylinder that keeps failing seals is telling you about rod finish, barrel condition or side loading — not about the seals. We strip and measure before we quote, so the price you approve is the repair the cylinder actually needs. Regular hours are Monday-Friday 6 AM-5 PM; the rush line runs 24 hours a day, every day of the year. Quotes are free, pick-up and delivery are free, and you talk directly with John Clark.

Frequently asked questions
Can you rebuild a Rexroth cylinder from a press or plant line?
Yes — industrial Rexroth cylinders are regular bench work here. We measure bore, rod and piston at teardown, renew what is worn, and pressure-test the rebuilt cylinder before it leaves.
My Rexroth cylinder drifts under load. Is that repairable?
Usually, yes. Drift points to internal bypass from worn piston seals or barrel wear. We measure at teardown and quote the repair that actually stops the bypass, not just a reseal.
