Harmonic drive use crossed roller bearing
SHF(SHG) series(Outer ring integraty,inner ring integraty)
Outer ring and inner ring are all integraty structure,mounting will have no affect on performance ,it can abtain stable running accurancy and torque.suitable for every kinds of SHF(SHG) series harmonic drives.

Lubrication
Bearing with high quality compound lithium-based grease in factory,so under normal using condition there is no need to add grease.but for bearing running ,in the inital stage ,the frictional torque will increase temporarily, frictional torque will be stable when grease uniformly adhere to raceway and roller.
If the bearing using condition change,general grease can not meet your requirements ,pls contact us.
