Second-Hand Gear Reducers — Buying and Selling

Browse second-hand gear reducers and servo gearboxes in this category. Compare the gear ratio (i), rated output torque, permitted input speed, angular backlash, shaft and flange dimensions and mounting position. For more detailed selection criteria, see our gear reducer buying guide.

Do not select by motor kW rating alone, including when choosing planetary gearboxes. Distinguish rated torque from peak torque. For connection to a servo motor, stepper motor or AC/DC motor, verify the shaft diameter, flange, coupling and adapter dimensions. Check whether the motor and connecting parts are included. A matching ratio or similar housing does not make units interchangeable.

To buy an item, open the product pages below and compare capacity and dimensions with new gearboxes. Your point of contact is the store identified on the product page. Confirm price, availability, delivery, specifications and item condition with that store. Listings are updated at intervals averaging 10 days. A sold item may remain visible briefly, so confirm stock before ordering.

The item should be identified as used, unused, boxed, repaired, faulty or for parts, with oil leaks, shaft play, bearing noise, damage and missing accessories disclosed. Review any maintenance records and the speed, load and duration of recorded tests. No-load operation does not replace testing under load. The scope of testing, any warranty terms and any claims of compliance with standards depend on the store's description. A boxed or unused item does not automatically carry a warranty.

To offer your gear reducer for sale, email the brand, full model code, quantity, working condition or faults, clear photographs of the item and its rating label, and your asking price to otomasyonavm@gmail.com. If the ratio is illegible on the label but is known, include it separately. We do not purchase products without an invoice. A submission does not constitute a commitment to purchase. OtomasyonAVM is not a platform where anyone can publish a listing directly.
