## Product Details and Benefits

The \*\*ST Fitness 8940 Treadmill Rear Idler Roller\*\* is listed under the \*\*Treadmill Rollers\*\* category. Its product identifier is \*\*RP471\*\*, which also serves as the listed SKU and barcode.

A treadmill’s rear idler roller sits behind the running surface and works with the belt as it moves around the deck.

It also allows you to replace the individual roller rather than searching for an unrelated or incorrectly sized component.

This product is identified specifically as a \*\*rear idler roller\*\*, so it is intended for the rear position of the treadmill. Buyers can use the clear part number, RP471, when checking service records, replacement-part lists, or equipment components.
