Retro-Fit and Drop-In Gearboxes & Gear Reducers

Whatever your requirements, we have a solution for you. Sumitomo Drive Technologies offers customized gearbox bases that allow our units to match the footprint of an array of existing applications and drop-in a unit to upgrade, replace and remove competitor gear boxes. With a wide range of options, our engineers can replace your unit with minimum impact on your application while delivering a premier product with performance and reliability.

Retrofitted Industrial Gearbox Replacement

With a custom transition base, the new low-speed shaft will be positioned exactly where the original low-speed shaft was. Compared to a standard gearbox, retrofitting with our large gearboxes provides maximum cost savings with minimal on-site modifications to your application. 

This option typically requires just relocating the motor mount. In order to minimize the impact of relocating the motor mount, we offer motor mounting options, such as flanged motor adapters for c-face and d-flange motors. 

Other options might include low-speed shafts with specific diameters or lengths and motor lanterns. In the diagram, the red circles indicate the existing bolt pattern of a customer's large gearboxes. Transition bases are made to match machine shaft height, ensuring that the low-speed shaft is aligned with the machine shaft.  

Drop-In Industrial Gearbox Replacements

Because downtime is such an important factor for your business, let us install a custom drop-in unit. Installation-ready units are designed to seamlessly integrate into existing applications. We understand that on-site modifications or reengineering your system isn't always an option. 

These stress-free units can have your application back up and running in no time. Custom gearing and shafting, fabricated steel housings, and more are all available. Same footprint, same shaft positions; it will literally drop into place.
