CORONEX (ER-P Series) High Precision Reducer 

It was 1975 when "Coronet Reducers" with original gear tooth profile, Circulute, was born. 40 years later, through continuous improvement, a new generation reducer for high precision control is now introduced.

Taking advantage of the circular internal gear shape, it has great characteristics such as "high efficiency", "zero backlash", "low noise", and "available hollow shaft" which expands the usage options. The new high rigidity reducer is perfect for robot joints and precision indexing for machine tools. The term "Circulute" is coined by Nidec-Shimpo, combining "circle" and "involute".
