Are these those special U joint washers?
 

I know I have them in my stash piles somewhere, but are these two those special U joint washers? If not, does anyone have one or two they'd be willing to sell?

Thanks,

Looks like you have the real deal, especially given the marks created by the shake-proof lock washer that was originally used for that application.

Re: Are these those special U joint washers?
 

Yes, those are the correct ones. There is also a truck one that is similar that can work as well.

Thanks, gentlemen. David, agree about the marks.

In a previous post, someone mentioned that these are actually a "spring"? Are they designed to allow some movement under load?

Re: Are these those special U joint washers?
 

No.....they are bellows washers.....crank the bolt down to the correct torque value and there will be no movement allowed.

Re: Are these those special U joint washers?
 

I don't think they are a spring. I believe they are a "bellvill" washer.
You can "Google" it.

Edit: belleville, sorry

Thank you, gentlemen. Makes sense.

You are correct in the technica/patentedl name "Belleville".......they are spring washers however, specifically designed for axial load applications.

Re: Are these those special U joint washers?
 

I agree.

I'm familiar with them from the electrical industry.
Swichgear, buss & terminations are a major consumer of belleville washers.

Re: Are these those special U joint washers?
 

We also used many Belleville/spring loading type washers during the manufacture of power tools and industrial equipment at the company I worked for.

Re: Are these those special U joint washers?
 

As I sell "Belleville" washers almost "daily" there are over 1500 listed combinations of these washers SO there are (or can be) VERY technical in both materials, thickness, load range, etc etc SO ordering a "replacement" could be catastrophe IF you don't know all the particulars!!!!! Just saying


I might also add......"Some" can get quite pricey too!!!!
