Airmasters were fitting these in the 1980’s, I have a few of their tuned HW77’s rifles with them fitted

How would a ptfe washer sandwiched between two steel washers fare?

I've just bought a txsr with one of these bearings fitted between the rear guide and the trigger block. It does shoot very well. Would it be advisable to remove it?

Trigger block is alloy so will wear in no timeOriginally Posted by gtfreight

Thank you, I will remove it before I use the gun again.

It won't wear the trigger block , if it's a flat race ie three piece , they are designed so one piece stays still, it's the whole point of a thrust race.

You'd be better with two PTFE washers between two steel washers. The coefficient of friction of PTFE on PTFE is similar to ice on ice.

Thanks. I shall now try to find some on my favourite auction site. I'm sure that the ptfe will be protected by the steel.

PTFE deforms and migrated , so you will probably see velocity varying , delrin is probably better.
Your piston rotates in the tx anyhow, just make sure your piston weight/ top hat isn't stuck and grease it .

I have noticed, admittedly in my budget guns that the rotation has been pushed back (layman's terms) to the rear of the spring guide vs the end block.
I saw this most visibly in my Paratrooper even though it's spring guide allows rotation there is a shiney circle worn into the rear block corresponding to a similar circle of the rear of the spring guide.
It just goes to show how important a good spring bearing set up is.

true....
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
