Product Details and Benefits

The rear idler roller sits at the back of the treadmill and works with the running belt and deck assembly. It provides a mounting and support point for the belt as it travels around the treadmill. A suitable replacement can help address a damaged or unavailable rear roller during treadmill repair or refurbishment.

Because this is a **preowned** part, it may show signs of previous use.

Replacing only the failed roller may also help avoid replacing a larger treadmill assembly when the roller is the component that needs attention.
