Not sure if anyone still goes down this route, Al. It is something I always fancied trying but never got round to. Many would say that using the polished steel washers that we tend to use anyway (or a combination of these and synthetic ones), to give a plain bearing work just as well and will prove more durable / reliable?
THE BOINGER BASH AT QUIGLEY HOLLOW. MAKING GREAT MEMORIES SINCE 15th JUNE, 2013.
NEXT EVENT :- August 3/4, 2024.........BOING!!
yeah i wondered a bout these some time ago
spose it depends if the springs turn as a norm ?
ive also wondered if you have a load of washers
at the guide end to get a plastic bush turned
instead it would certainly look better

Always a chance this happening with bearings under load.
Brinelling /ˈbrɪnəlɪŋ/ is the permanent indentation of a hard surface. It is named after the Brinell scale of hardness, in which a small ball is pushed against a hard surface at a preset level of force, and the depth and diameter of the mark indicates the Brinell hardness of the surface. Brinelling is permanent plastic deformation of a surface, and usually occurs while two surfaces in contact are stationary (such as rolling elements and the raceway of a bearings) and the material yield strength has been exceeded.
Brinelling is undesirable, as the parts often mate with other parts in very close proximity. The very small indentations can quickly lead to improper operation, such as chattering or excess vibration, which in turn can accelerate other forms of wear, such as spalling and ultimately, failure of the bearing.

I have some thrust bearings both ball and roller, I have often considered trying this in a top hat.
One thought I had if the spring becomes slack under recoil, the bits may fall out of the bearing.
Repariere nicht, was nicht kaputtist.
I did try it, and it does "work", but I couldn't detect any advantage over just a couple of hard steel slip washers and a dab of moly... on the downside however, their physical constraint mean they are tricky to fit to many smaller clylinder bore guns, plus there are the concerns about long term reliability.
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
