Gearbox / Servo Speed Reducer Repair
Save critical downtown by repairing your gearboxes
Industrial Gearbox Diagnostics
Isolate the Failure Mode Before Catastrophic Breakdown
In high-precision CNC manufacturing, industrial automation, and heavy robotics, a servo speed reducer or gearbox handles extreme force and tight spatial tolerances. When a unit begins to drift, identifying the exact failure mode early saves thousands in secondary damage to motors and drive shafts.
Common Warning Signs Your Gearbox Needs Repair
Grinding or Whining
Unusual grinding, whining, or clunking sounds during operation are often the first sign of worn gear teeth, damaged bearings, or insufficient lubrication inside the gearbox.
Excessive Vibration
If your machine is vibrating more than normal, it may indicate gear misalignment, a damaged shaft, or worn internal components that are no longer running true.
Overheating
A gearbox running hotter than normal is a red flag. Overheating is commonly caused by oil breakdown, overloading, or internal friction from worn components.
Oil Leaks or Contamination
Oil seeping from seals or evidence of contaminated fluid inside the gearbox signals seal failure or internal damage that will worsen rapidly if left unaddressed.
Loss of Power or Speed
A gearbox that can no longer maintain output speed or torque under load often has worn gear teeth, slipping components, or significant internal wear that needs immediate attention.
Increased Backlash or Slop
Noticeable play or looseness in the output shaft is a classic sign of worn gear teeth or bearing wear. In precision CNC and servo applications, even minor backlash causes positioning errors and scrap parts.

Repair vs. Replace
Why Repair Is Almost Always The Right Call
Fraction Of Replacement Cost
A new OEM gearbox can often cost several times more than a professional repair. In many cases, a properly rebuilt gearbox delivers the same performance and reliability as a new unit while significantly reducing replacement costs.
Back In Production Faster
A new OEM gearbox may require weeks or even months to arrive, resulting in extended equipment downtime. Our gearbox repair services offer significantly faster turnaround times, with expedited repair options available to help get your equipment back into operation as quickly as possible.
No Replacement Available? We Still Fix It
Older and discontinued gearbox models can be difficult or impossible to replace through the original manufacturer. Our in house machining capabilities allow us to manufacture replacement components, enabling us to repair and rebuild obsolete gearboxes that are no longer supported by the OEM.
Rebuilt To Original Spec
Our gearbox repair process includes complete disassembly, detailed inspection, precision cleaning, and rebuilding to original specifications. Before shipment, every gearbox undergoes testing to ensure reliable operation and performance.
