\# Precor TRM 221, 223, 243 Treadmill Rear Idler Roller RP279

The Precor TRM 221, 223, 243 Treadmill Rear Idler Roller (RP279) is a replacement treadmill roller designed for the rear section of compatible Precor treadmill running decks. It helps replace the original rear idler roller when the existing component requires service or replacement. This part suits equipment owners, treadmill repair technicians, fitness centers, and service departments maintaining Precor TRM-series machines.

## Product Details and Benefits

This product is a \*\*treadmill rear idler roller\*\* for selected Precor models. The rear idler roller forms part of the treadmill belt-running system and sits at the back of the treadmill deck. Replacing a worn or damaged roller can help support proper maintenance of the treadmill’s running belt assembly.

The product name is \*\*Precor TRM 221 223 243 Treadmill Rear Idler Roller\*\*, and its part identification number is \*\*RP279\*\*. The product category is \*\*Treadmill Rollers\*\*. Its SKU and barcode are also listed as \*\*RP279\*\*, which can help service teams match the part to an order, maintenance record, or replacement request.

Use this component when the original rear idler roller on a compatible treadmill needs replacement. A correctly matched replacement part helps you maintain the equipment with a component intended for the specified treadmill models, rather than trying to adapt an unrelated roller.

## Compatibility and Applications

The RP279 rear idler roller is identified for use with the following Precor treadmill models:

\- Precor TRM 221  
\- Precor TRM 223  
\- Precor TRM 243

This part is intended for Precor treadmill equipment, not for general-purpose treadmill use across all brands and models. It works as a replacement for the rear idler roller on the compatible TRM-series treadmills listed above.

Before ordering, compare your treadmill’s model information with the compatibility details shown here. If your equipment has a model variation, updated assembly, or different serial-number range, confirm that RP279 matches your existing part and service requirements.

\## Why Choose This Replacement Roller

The Precor RP279 gives you a clearly identified replacement option for maintaining a compatible TRM-series treadmill. Its model-specific listing makes it easier to search for the correct rear treadmill roller by brand, equipment model, and part number. It can help simplify parts sourcing for routine treadmill maintenance or repair work.

This replacement part may suit customers who need a Precor TRM rear idler roller rather than a complete treadmill belt assembly or an entire rear roller system. Confirm the failed component before ordering so you receive the part your repair requires.

## Before You Buy

Verify that your treadmill is a \*\*Precor TRM 221, TRM 223, or TRM 243\*\* and that the required part is the rear idler roller. The listed part number is \*\*RP279\*\*, and the SKU is \*\*RP279\*\*.

The available product information does not specify roller dimensions, construction material, color, included hardware, installation instructions, package quantity, or warranty terms. Check those details with the seller if they are important for your repair. If you need to confirm serial-number compatibility, have your treadmill’s serial information available before placing the order.
