# Horizon Fitness T5 Treadmill Rear Idler Roller (RP354)

\## Horizon Fitness T5 Treadmill Rear Idler Roller (RP354)

The Horizon Fitness T5 Treadmill Rear Idler Roller is a replacement treadmill roller designed for the rear section of a compatible Horizon Fitness T5 treadmill. This component supports the running belt and helps it move around the back of the treadmill deck. If the original rear roller shows signs of wear or needs replacement, this part can help restore the correct roller arrangement in the treadmill.

## Product Details and Benefits

This product is a treadmill rear idler roller from Horizon Fitness. It is identified by part number \*\*RP354\*\* and SKU \*\*RP354\*\*. The roller belongs to the \*\*Treadmill Rollers\*\* product category and is intended for use as a rear roller component on the specified treadmill model.

The rear idler roller sits at the back of the treadmill and works with the running belt as the belt travels around the deck. A correctly matched roller is important because the rear roller forms part of the belt support and tracking system. Replacing a worn or damaged component may help the belt move as intended and may support routine treadmill maintenance.

The product name identifies this item as a \*\*Horizon Fitness T5 rear idler roller\*\*. This makes it useful for treadmill owners, repair technicians, and service professionals who need to replace the rear roller rather than replace the entire treadmill. The part number gives you a clear reference for comparing the replacement with the component currently installed on your equipment.
