The rear idler roller forms part of the treadmill belt system. Its position at the back of the machine allows the walking belt to pass around the rear of the deck while the roller helps maintain the belt’s path. Replacing a damaged or worn roller can support a repair when the existing component no longer meets the needs of the treadmill assembly.

Because this is a preowned NordicTrack treadmill part, it may suit customers who need an original used component for a repair or restoration project. A preowned part can also provide a practical option when matching an older treadmill model. The condition means the item has had previous use, so buyers should review the product photos and compare the part carefully before ordering.

## Compatibility and Applications

This part is listed as a \*\*NordicTrack C2155 NTL07707.1 treadmill rear idler roller\*\*. It is intended for use with the rear belt and roller assembly of that specific treadmill model designation. It is not a universal treadmill roller, and the listing does not confirm compatibility with other NordicTrack models or brands.

Use this component when servicing the rear section of a compatible NordicTrack C2155 treadmill. It may be relevant when replacing the original rear idler roller as part of a treadmill belt or roller repair.

## Before You Buy

Confirm that your treadmill is a \*\*NordicTrack C2155 with model number NTL07707.1\*\*.
