Timken 008-10853 or 00810853 is a belt idler ball bearing pulley: a pressed-steel idler with a precision ball bearing and rubber seals built in, so it works as a self-contained unit. The pulley rides along the belt as a guide wheel and keeps it running true on its path.
A worn one tends to squeal or screech, wobble on its mount and let belt tension drop, which can end in belt slip. Left running once the bearing is rough or loose, it can chew up the belt or let it come off. A genuine Timken part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
