Onvio reducers are designed with cantilevered needle bearing cam followers and rollersnot with pins and bushings found in other cycloidal designs. This allows for a con-trolled pre-load between the cam andcam followers, assuring zero backlash. Pre-load is maintained throughout the design life of the reducer.Every cam follower is in contact at alltimes, the load is equally shared. This guarantees consistently high torsional rigidity independent of load position.With a high capacity output bearingand output flange, Onvio's cycloidal reducer can support most loads. Machine designs are...

Standard Grease Extreme Cold Temps Extreme High Temps > 1 1 The Dojen is grease lubricatedand sealed for life. However, in some high cycle applica- tions or in environments that can prematurely cause lubri- cant to breakdown, we rec- ommend purging old grease with fresh new grease. The reducer is equipped with grease ports on the outer diameter. Contact Onvio cus- tomer service for lubrication procedures and available equipment.
