Our CFTMA Test has passed 11,500,000 revolutions on a single caster! We have been tracking the performance of our Maintenance Free 68 Series rig for almost 3 years now. The test applies a load to the caster as it swivels on a metal platform cart. We recently made a video describing the CFTMA test in more detail; check it out at this link https://www.youtube.com/watch?v=7moFcTHySWk
