The Trion's unfortunately, have unsealed bearings inside from the factory, not a well thought out part insertion in my opinion.
My Trion TR130 got wet and the bearings had some rust in them..used a micrometer to find the mm size of the bearings and found replacements on Amazon for $8.99 for 10 bearings. Replaced the bearings and the Trion is working good as new ever since.
I'll post the link to the bearings that I ordered for my TR130 but you need to check the size of your bearings with a micrometer to be sure you get the correct replacement bearings.
