What is a Cyclo Drive anyway?

Found in a machine’s gearbox, a Cyclo Drive or Cyclo Reducer effectively converts power to torque by significantly reducing speed with the help of its spare part called eccentric bearing.

Made by leading Japanese company, Sumitomo Drive Technologies, this innovative product is used in industries related to textile, steelworks, conveyors, automotive plants, and construction equipment manufacturing.

Trusted Japanese Brand 

Founded more than 400 years ago by Masatomo Sumitomo, Sumitomo Group of Companies today has reportedly over USD400 billion annual sales with over 267,000 employees across the globe. Under its umbrella is Sumitomo Drive Technologies (also known decades ago as Sumitomo Heavy Industries) which is renowned for having manufactured Japan’s first ever Cyclo Drive in the late 1930s. Since then, it expanded its market base in Europe especially after its full acquisition of German based company, CYCLO Getriebebau GmbH, whose founder, Lorenz Braren, was the inventor of the Cyclo Drive technology.


Quick Fix Tips 

Just like any other case of mechanical failure, Sumitomo bearing damage mainly boils down to improper lubrication, the root cause of sudden temperature increase, which if left undetected can decrease a Cyclo Drive’s service life and all of its components.

As a preventive measure, the following manufacturer quick fix tips can be used whenever necessary.

  1. Eccentric bearing replacement plus adequate grease application after cleaning and flushing the Cyclo Drive  
  • For increased noise level caused by inadequate bearing lubrication
  • Output shaft fails to turn due to damaged eccentric bearing
  1. Reduce the load or choose another Cyclo Drive model with the correct load capacity
  • For increased noise level caused by inadequate bearing lubrication

Last but not the least, to ensure proper eccentric bearing lubrication, the Sumitomo Cyclo Drive’s shaft should be rotated quarterly and its factory must be contacted should there be a case of planned storage for more than a year.
