Brown&Sharp Spindle Repair

Brown & Sharp Spindle Rebuild

The front housing of this spindle was not round and out of ISO specification. This deforms the outer race of the bearings causing stress to the balls and raceways of the bearings. Eventually the bearings wear prematurely to the point of failure. We repair this condition in our grinding department by grinding out the housing bore oversized, chrome plating it, then finish grinding it to size while maintaining parallelism with the rear housing bore.

Possible cause of failure:
Rear bearing failure
Front housing egged

Recommended action:
Clean, inspect overall dimensions.
Grind plate grind front housing
Replace bearings.
Adjust preload, balance, assemble and break in. Final quality control inspection.
