Flender Gearbox Repair in Fontana
Some of the heaviest lines in the region are powered by Flender drives — units badged Flender, Siemens and Winergy at different times over the years. When one needs more than a seal kit, the whole job happens in-house at our Fontana shop: teardown, inspection and rebuild, plus manufacture of replacement gears for Flender units the factory has stopped supporting.

Flender drives: helical, bevel-helical and planetary
Flender helical and bevel-helical gear units are rebuilt here, along with planetary stages and the shafts, bearings and gearing they contain. Measurement comes before quoting on every unit, so the scope of repair reflects the wear actually present in your drive rather than a guess made over the phone. Any gear worn past its limits is re-cut or manufactured new in the same building, matched to its housing and to the duty the drive performs.

Flender Gearbox Repair in Fontana · Our Fontana, CA workshopFactory support comes to an end. Ours does not.
Ownership and badges across the Flender lines have shifted again and again, and support for older units can be slow to come — or simply not offered. A local rebuild bench backed by its own gear manufacturing closes that gap, because your drive gets assessed on its condition instead of its catalog status. Regular hours run Monday–Friday 6 AM–5 PM; rush and emergency repair runs 24 hours a day, 365 days a year, and quotes, pick-up and delivery are free.
- Rebuilding Flender helical and bevel-helical gearboxes
- Repairing planetary stages and manufacturing their gears
- Renewing shafts, bearings and seals
- Cutting replacement gears for models no longer supported
- Rush service around the clock when a plant is down

Questions customers ask us
Can parts be obtained for an older Flender gearbox?
When factory parts cannot be had, or cannot arrive fast enough, the gearing and shafts are manufactured here from the original parts — that capability is the core of our gear shop.
How quickly can a Flender rebuild be turned around?
Turnaround hinges on the damage the teardown reveals. The 24-hour line exists for rush work — call (800) 821-3404 and you will get a straight answer on timing.
