Bearing Cartridges are used with the 14" Treadmill Wheels and the 15" Chin-Sprint Wheels. Please be sure to make the proper size selection for your wheel. The 2 inch cartridge is suitable for any Treadmill 14” or the older model of the Chin-Sprint Wheel purchased in March 2021 or earlier. The 2-1/2 inch cartridge is suitable for the new model Chin-Sprint wheel purchased in April 2021 or later.
Maintenance: Wheels have a center bearing cartridge that is subject to wear-and-tear over time with continuous use, but this replacement will make any old wheel work like new! Some customers go years without replacing it, while others may have to replace it once or twice per year. Product warranty is 60 days, where Exotic Nutrition will provide a complimentary replacement center bearing cartridge.
For help with installing the new bearing cartridge, watch our Treadmill Wheel Assembly or Chin-Sprint Wheel Assembly video online.
