## PaceMaster Pro Select Treadmill Rear Idler Roller (RP553)
The PaceMaster Pro Select Treadmill Rear Idler Roller is a preowned replacement treadmill roller identified by part number and SKU RP553. It is intended for the rear roller position on a compatible PaceMaster Pro Select treadmill. If your treadmill’s rear roller has worn, become damaged, or no longer supports the belt correctly, replacing the roller may help restore the proper belt-support components in the machine.
This product is a **PaceMaster treadmill rear idler roller**. The rear idler roller sits at the back of the treadmill and works with the walking belt as part of the belt-support assembly. It is a specific replacement component rather than a complete treadmill assembly, walking belt, motor, or front drive roller. Buyers should confirm that their existing treadmill requires the rear idler roller before ordering.
