We sell replacement motors, bearings, guides, shafts, retainer clips, barrels, retainer rings and lids.
Thumler's Model A-R6 Belt
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.
A-R6 Tumbler Bearings
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.
Stop Squeaky Bearings
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.
Needle-Tip Oil Bottle
Have your own SAE20 motor oil or general purpose oil? Use one of these needle-tip bottles to accurately dispense it on tumbler bearings and motors. Keep your tumbler running smooth and quiet.
Thumler's A-R6 Barrel Guides
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 Shaft Retainer Clips
Retainer clips are used to hold the bearings on the end of the shafts and to hold the nylon rollers in the proper location on the idler shaft.
Thumler's Tumbler Nylon Roller
After years of use, the nylon rollers on the idler shaft may wear down and need to be replaced. We offer a set of two rollers for the A-R1 and A-R6 tumblers and a set of three rollers for the A-R2 and A-R12 tumblers.
Thumler's Rubber Roller
These rubber rollers for the drive shaft are what give the barrel traction and keep it turning to tumble the rocks inside. Replace worn rollers for optimum tumbling action. A set of two rubber rollers is needed for the A-R1 and A-R6 tumblers while a set of three rollers is needed for the A-R2 and A-R12 tumblers.
Thumler's A-R6 Drive Pulley
This pulley fits the drive shaft of Thumler's A-R6 rotary tumblers. It will also fit any of the following tumblers: Thumler's MP-1, A-R1, A-R2, A-R12, Model B, Model T, and Model T2.
Thumler's A-R6 Drive Shaft
A replacement drive shaft for the Thumler's A-R6 rotary tumbler. Easy to replace: just remove the belt, lift out the old shaft, snap the new one in place, and replace the belt. Includes: Shaft, rubber rollers, bearings, pulley and retainer clips.
Thumler's A-R6 Idler Shaft
A replacement idler shaft for the Thumler's A-R6 rotary tumbler. It is a complete shaft with all needed components that can be replaced in a minute with no tools required.
Thumler's A-R6 Barrel Lid
This is Thumler's A-R6 barrel. It is made out of plastic which means it will eventually wear through, so having an extra one on hand is a good idea.
Thumler's A-R6 Barrel Retaining Ring
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.
Thumler's A-R6 Tumbler Barrel
This Thumler's Model A-R6 rock tumbler barrel has a 9-pound capacity. This complete barrel includes the soft rubber barrel, the retaining ring and plastic lid. Having an extra barrel for polishing is recommended to reduce the chance of contamination from the other grit sizes.

A-R6 Tumbler Motor Pulley
This pulley fits the motor on all A-R model Thumler's Tumblers. This Thumler's A-R6 pulley has a 1/4" bore diameter and 3/4" outside diameter. A 2mm allen wrench is needed to adjust or install pulley.
This motor fits the Thumler's A-R6 rock tumbler. It is thermally protected, which means it will automatically shut off if it gets too hot. It is very easy to attach and get back to tumbling.
Thumler's A-R6 Motor Mounting Nuts
Two keps nuts (nuts with attached, free spinning, star-shaped lock washers) are used to keep the motor in place. They screw onto the two motor-mounting bolts where they extend through the motor-mounting brackets. A 9mm wrench is needed to install.
