Does hard chroming grinding create a surface suitable as ...

Jan 09, 2018  Does hard chroming grinding create a surface suitable as a bearing race? Sometimes one finds bearing races integral to the shaft and housing - in this case needle bearings. If you were redoing such a spindle, is hard chroming and grinding going to create a durable bearing surface? I've had parts hard chromed, its ideal for say restoring a ...

MAHLE Aftermarket North America Installation Tips

The surface lay generated by grinding would cause abrasion to the bearing surfaces if left unpolished. By polishing in the direction shown in either the figure 3 or 4, the surface lay is reversed by the polishing operation removing fuzz created by grinding and leaving a surface lay which will not abrade the bearing surface.

Grinding and Polishing Guide Buehler

Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel.
