# Cardiostrong TX90 CST-TX90-2 Treadmill Rear Idler Roller (RP327)

\## CardioStrong TX90 Treadmill Rear Idler Roller RP327

The CardioStrong TX90 CST-TX90-2 Treadmill Rear Idler Roller (RP327) is a replacement roller for the rear section of a compatible CardioStrong treadmill. It forms part of the treadmill belt assembly and helps maintain the correct belt path at the back of the running deck. If the original rear idler roller is worn, damaged, or needs replacement during treadmill servicing, this part may help restore the machine’s belt assembly to its intended configuration.

## Product Details and Benefits

This product is a treadmill rear idler roller made for the CardioStrong TX90 and CST-TX90-2 models. As a replacement component, it is intended to replace the original rear roller rather than serve as a general-purpose treadmill part. The roller’s position at the rear of the treadmill makes accurate model and part identification important before ordering.

Replacing a damaged or unsuitable rear roller can support proper alignment of the treadmill belt assembly. It may also help when servicing a treadmill that shows signs of a faulty rear roller or requires replacement of the original component. The correct replacement part allows a repair technician or experienced owner to address the roller itself without replacing the entire treadmill.

This part may suit treadmill repair, maintenance, refurbishment, or replacement work where the existing rear idler roller requires removal.

The model name, part number, and roller measurements should match your equipment and the original component.

\### Why Choose This Replacement Part

Choosing the correct rear idler roller helps keep the repair specific to the affected treadmill component. The RP327 part number makes it easier to compare this item with service records, an existing roller, or a parts list for the CardioStrong TX90 or CST-TX90-2. It can be a practical option when you need to replace the rear roller without sourcing an entire treadmill belt assembly.

## Before You Buy

Confirm that your treadmill is a \*\*CardioStrong TX90 or CST-TX90-2\*\* model. Check the original rear idler roller and compare its measurements with the roller-measure reference on the product page. Also verify the part number \*\*RP327\*\* before placing an order.

The available product information does not specify the roller’s material, color, dimensions, package quantity, installation hardware, warranty, or installation instructions. Confirm these details if they are important for your repair. Installation should follow the treadmill manufacturer’s service procedure, and the treadmill should remain disconnected from power while work is carried out.
