Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If needles integral to semiconductor crystal grinders
Statistical notes place grinder parts (including bearings) under specific machinery parts.
If supplied with cage and races
Complete bearing subassemblies become 'other parts' rather than individual needles.
