(2) Replacement Bearings for Treadmill Wheels (fits both 11" or 14" wheels) and the Chin-Sprint Wheel (15").
Wheels have a center bearing package that is subject to become loose and wear over time with continuous use, and will squeak or break if the wheel is used when the center screw is loose. In order to maintain your Wheel, check the bearings on a regular basis to prevent it from becoming loose and wearing. When cleaning this wheel, tighten the center screw and put a few drops of mineral or baby oil on the bearing package.
