The Timken B127 is a trailer refrigeration unit transmission drive belt, a genuine Timken part from Pro Gear and Transmission. A drive belt links pulleys and passes power from one shaft to the other through pulley grip. When a belt stretches or slips, the speed ratio between the pulleys drops, which can show up as weaker output from the driven component. Fatigue from flexing around the pulleys is the main cause of belt failure, and too little tension lets the belt slip while too much shortens belt and bearing life. Call us to confirm proper fit.
