Product Details and Benefits

A rear idler roller helps guide and support the treadmill belt at the back of the running deck. The roller turns as the belt moves, allowing the belt to travel around the rear of the treadmill. Replacing a damaged or worn roller may help address problems related to the rear belt-support assembly and provide the correct replacement component for the machine.

This part is listed specifically as a **True Fitness rear idler roller**, rather than as a universal treadmill roller. That makes the model and part-number check especially important. The listing does not provide material, color, roller diameter, shaft dimensions, bearing specifications, or installation hardware details. Do not assume that these specifications match another treadmill roller unless you confirm them separately.

Compatibility and Applications

The **RP408 rear idler roller is a replacement part for the True Fitness TPS800-19 treadmill**. It replaces the original rear idler roller used to support the treadmill running belt. The listed serial reference is **19-TPS800844G**.

This roller is intended for treadmill repair and maintenance. It may suit a treadmill owner, service technician, fitness-equipment repair shop, or maintenance department that needs to replace the rear roller on the specified True Fitness equipment. Compatibility information beyond the TPS800-19 model is not provided, so avoid treating this part as compatible with other True Fitness models or different treadmill brands without confirming the original part number and measurements.

### Why Choose This Replacement Roller?

Choosing the correct rear idler roller helps you match the replacement part to the treadmill’s original belt-support system. The clearly listed **RP408 part number** makes it easier to compare this roller with a service record, existing component, or equipment-parts list.
