Rolling bearing surface and end surface

(1) surface and end surface roughness inspection method
End of the rolling bearing surface and roughness of rules with contour arithmetic average deviation Ra as evaluation parameters, measure principle rules using contourgraph. When does not have outline instrument, can be compared with the roughness of standard parts inspection. When two ways to check the results controversial, the use contourgraph measured results shall prevail.
Such as the roughness of standard parts, should be checked with the ring with the same shape,Roller Bearings and use the same material and processing method of manufacturing.
(2) the surface and end surface roughness evaluation criteria
In evaluation, specific for the inner hole and outside cylinder, should be on the surface intervals of about 120 ° in three locations, such as the end of chamfer should be in its place in the plane in three locations, such as in the third part on the average of the measured Ra parameters, should not be greater than the relevant data, otherwise is not qualified.
