Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If single row deep groove construction
Deep groove bearings have specific statistical breakout from other radial types.
If dedicated replacement parts for polishing machines
Parts exclusively for listed semiconductor wafer processing machines classify separately.
If precision angular contact for polishing head spindles
Axial load handling in polishers requires angular contact classification.
