Pro-Form Performance 400i PFTL59515.4 Treadmill Rear Idler Roller (RP497)

## ProForm Performance 400i Treadmill Rear Idler Roller

The ProForm Performance 400i PFTL59515.4 treadmill rear idler roller is a replacement roller for the rear section of a compatible treadmill running belt system. This preowned ProForm treadmill part helps support and guide the belt at the back of the deck. If your original rear roller is worn, damaged, missing, or no longer suitable for use, replacing it with the correct idler roller can help restore the treadmill’s belt assembly.

This part is listed for the **ProForm Performance 400i treadmill, model PFTL59515.4**. It carries the product part number **263724** and the seller SKU **RP497**. The product listing identifies it as a rear idler roller, so it is intended for the rear position rather than the front drive-roller position. Confirm the required roller location before ordering.

Product Details and Benefits

The rear idler roller sits at the back of the treadmill and works with the running belt and deck assembly. Its position helps maintain the belt’s path as the belt moves during treadmill operation. Replacing a damaged or worn rear roller may help address problems related to the rear belt support system, although the exact cause of a treadmill issue should be checked before replacing any part.

This item is sold in **preowned condition**. A preowned replacement part may show signs of previous use, handling, or storage. Inspect the roller carefully when it arrives and compare it with the part removed from your treadmill before installation. Because the product page does not provide dimensions, material details, or additional technical specifications, use the part number and treadmill model as the main identification references.
