Harmonic drive bearings

SHF Bearings

Industrial robots bearings

SHF-20/SHG-20 Dimension-54x90x18.5mm Bearings

Products structure

Harmonic drive bearing is cross roller structure.According to its application area there are two types one is our ring split and inner ring integraty another one is outer ring and inner ring all integraty.Rolling body are cylindrical rollers which arranged orthogonality,this structure can make one bearing can bear the load from every direction e.g. radial,axial and tilting torque etc. Bearing with high rigidity,rotation accurancy and load carrying capacity. This series bearing has compact appearance,with mounting hole,customer can mount directly,suitable for every kinds of harmonic drives.

Harmonic drive bearing series

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.

Mounting Method

Mounting caution

Pls clean up the parts e.g bearing seat ,axis etc,Which related to the bearing mounting. Check the burrs(make sure good fit tolerance between inner ring of bearing seat and outer ring of bearing, shaft neck and inner ring of bearing)

When tightening scew, Retaining bolt locking should be divided to 3~4 stages from incompletion locking to completion locking,according to the “ + crossing method” again and again.

Note

pls do not disassembly the bearing,for it is adjust by professional workers and to keep good preload and grease. If it runs abnormally after you receiving the bearing ,pls contact us.

Besides, bearing working temperature is -20℃~+80℃,if not ,pls contact us.
