Jim, if you do a search, a lot of people have suffered failures with the so called "Kevlar" pilot bushing.

Since I am familiar with the material, I did an internet search and what they are calling "Kevlar" is actually a Nylon bushing and the reason why they do not last. So in a nutshell, I believe they are selling a Nylon product by giving it a flashy name.

Kevlar's properties are not conducive for such application. Delrin or Polyether Ether Ketone (PEEK) materials would be.
