Gearbox & Spare Parts

Source gearbox-related components and spares for machinery repair with close attention to the original specification. Gearbox work is sensitive to shaft dimensions, mounting, input and output arrangements, ratio, lubrication and application load.

Verify before replacing

Use the gearbox maker, model, identification plate, original part number and key dimensions wherever available. Confirm shaft size, spline or keyway details, mounting pattern, gear ratio, input arrangement, lubricant requirements and any sealing specification before selecting a replacement.

Gearbox & Spare Parts FAQs

Can a gearbox be selected only by its ratio?

No. Ratio is only one part of the specification. Match mounting, shafts, torque duty, input, output, sealing and application requirements as well.

What signs indicate a gearbox needs inspection?

Unusual noise, vibration, heat, oil leakage, difficult operation or metallic contamination in lubricant are signs to investigate before continued use.
