3120-01-251-1681 An item of any peripheral shape usually having one flat or spherical surface and a centrally located hole. It is designed for applications involving moving (kinetic) loads.

The thickness must not exceed 25 percent of the outside diameter of the shortest distance between peripheral flats (when thickness and/or outside diameter is designated as a tolerance dimension, the maximum dimension will be used to determine compliance).

What Our Customers Say
Thank you very much for the excellent service and professional customer care.
The service was excellent. I can think of no improvements to date that you can make regarding internet sales.
The representative for WBParts was efficient & handled our request in a timely & professional manner.
Tried two other sources, neither of them responded, was all done online, never spoke to anyone.
The response is quick and the price is often very good. We are completely satisfied.
