Thumler's A-R2 bearings are made of durable polyethylene. Bearings are simple to replace. Remove the retainer ring, slide the old bearing off, put the new one one and replace the retaining ring.

Thumler's A-R2 tumbler barrel guides are made of a durable nylon. You won't replace these often but when you do it is easy to do.
