Thumler's Tumbler Bearings
Thumler's bearings are made of polyethylene. These bearings fit all Thumler's tumblers except for the MP-1 Tumbler.
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.
