Product Details and Benefits

- **Product type:** Treadmill rear idler roller
- **Brand:** NordicTrack
- **Compatible model listed:** C2155, model NTL07707.1
- **Part number:** 254305
- **SKU:** RP579

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

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.
