Callout on Surface Finish

On one of our drawings there is a call-out on the symbol in position c of SPBR. We are at a loss of what this abbrevation means

That part is a thin stamped part (0.15 mm)

Looks like they don't specify the surface finish...but call out only the method by which the SF is achieved? Doesn't make sense to me...

You need to ask the customer.

It is not on the customer drawing...it is one a drawing made by our Japanese mother company..getting information from them is almost always difficult. I thought I would check here first as this is a great (and much more responsive) resource!

The only SPBR I could identify was a specific type of liner bearing with a unique motion pattern. Is it possible that they are specifying that you use this linear bearing?

That's what I found..but in the application "a small stamp item - looks like a washer - that serves as a valve in a shock absorber ( what we call a damper) that answer didn't seem to make any sense!

If your dealing with a stamped part, it's a bogus callout. It would require a subsequent process.
