Pivot washers CNC machined and hand finished from solid phosphor bronze. These are intended to replace cage bearings of the same same.
- One set equals two washers
Quality product. I had to take a lil material off on the stones. To get no blade play the action was initially extremely tight so they might come a tiny bit thick. No complaints about the quality of the product though and better to need to slim them a bit than to have them too thin.
I took out the original bearings out of my Aus10a Demko AD 20.5 (with Liners) and replaced them with these.
The action does not get gritty when cutting through sandbags or other sandy/dusty environments.
The trade offs are minimal in that they stay cleaner longer without sacrificing too much as far as "Action" goes. The lock up is solid even with aftermarket scales*.
I even recommended these to a friend and he seems equally as happy swapping out the bearings of his 20.5.
*I have after market scales (Rock Scale Designs) on my 20.5 that require steel race washers (To prevent bearings from eroding the titanium.) I kept the race washers in the pivot along with the the new PB washers and the knife still kept a solid lock up with no blade side to side or front to back.
***If you have aftermarket scales that require steel race washers then KEEP THEM IN THE PIVOT. Other than that, if you have the original liners installed, the swap should be a breeze.***
