Influence of groove wall thickness difference between inner and outer ring of deep groove ball bearing on groove grinding?

Generally speaking, the outer ring of the deep groove ball bearing does not require a difference in wall thickness, as long as the ellipse, 

groove curvature and roughness meet the process requirements.

The inner ring grinding is generally divided into two kinds of 1 ditch grinding. The outer diameter of the 2 inner rings is furred.

A ditch grinding is grinding the groove first and then grinding the inner warp. If the triangular edge of the groove is unqualified, 

the wall thickness difference of the inner warp will be large.

Branch groove grinding groove triangular edge "wall thickness" is not good.

Common reasons 1 eccentricity is too small. 2 The contact Angle of the lower support is too small. 3 Excellent grinding wheel granularity. 

4 Grinding speed is too fast.

Two inner ring outside diameter grinding groove normal process process first grinding the inner warp and then grinding the groove. 

If the inner channel wall thickness is not qualified, it will also lead to a large difference in trench wall thickness.

Common reasons 1 eccentricity is too small. 2 The contact Angle of the lower support is too small. 3 Excellent grinding wheel 

granularity. 4 Grinding speed is too fast.
