Belt for Thumler's tumblers

Thumler's Model A-R6 Belt


Only $6.99
Replacing a worn out A-R6 belt is one of the easiest fixes on the tumbler. No tools are required for the fix. It is a good idea to have an extra belt lying around in case a belt breaks in the middle of tumbling a batch of rough.
Thumler's tumbler bearings

A-R6 Tumbler Bearings


Four for $7.99
Thumler's A-R6 bearings are made of polyethylene. Bearings are simple to replace. Remove the retainer clip, slide the old bearing off, put the new one on and replace the retainer clip. We suggest purchasing some extra retainer clips just in case you damage some while removing or replacing them.
3-in-one oil

Stop Squeaky Bearings


Only $4.99
We oil our Thumler's Tumblers every 30 days (or after each batch of rocks) with 3-IN-ONE Multi-Purpose Oil or SAE20 motor oil. Only one drop on each bearing. See our article for photos and detailed instructions.

Thumler's nylon guides

Thumler's A-R6 Barrel Guides


2 for $3.99
Thumler's A-R6 tumbler barrel guides are made of nylon which makes them durable. You won't have to change these very often but when you do it is a simple job. Remove the retainer clip, remove the bearing and old guide, slide on a new guide and replace the bearing and retainer clip. Purchasing some extra retainer clips in case you damage one is a good idea.

Thumler's 9lb barrel lid (A-R6)

Thumler's A-R6 Barrel Lid


Only $7.99

Thumler's A-R6 Barrel Retaining Ring


Only $6.99
This retaining ring is used to secure the lid on a Thumler's A-R6 Tumbler barrel. Note: This new retainer ring will appear much smaller than the one that you're replacing. That is because it hasn't been stretched out. It will fit the barrel, but it may be tough to stretch at first. In the video below, we share a tip on how to do it.
