Product Details and Benefits
This product is identified as the **Cybex 525t treadmill rear back idler roller** and carries the part number and SKU **RP104**. It is sold as a used fitness equipment part. Each part has been carefully inspected by skilled technicians to support reliable performance and safe use.
Replacing a worn, damaged, or missing roller can help you maintain the treadmill’s original mechanical assembly and keep the equipment in service. Using the correct model-specific roller also helps avoid the uncertainty that comes with adapting an unrelated treadmill part. Because this component is listed specifically for the Cybex 525t, it provides a clear reference point when sourcing a rear idler roller for that machine.
The roller may show differences in appearance from the product image. The seller carries multiple units, so the exact part you receive may look slightly different from the photograph. However, the seller states that the part will be the exact model and part type shown in the listing.

## Why Choose This Used Replacement Part?
A used, inspected component can help you repair existing equipment without replacing the entire treadmill. It also supports a more practical and sustainable approach to equipment maintenance by extending the service life of fitness parts and helping divert usable components from landfills.
The technician inspection provides an important buying detail for customers who need a functional replacement part rather than an unverified salvaged component. Always use the model and part number to confirm that this roller matches your repair requirements.
Before You Buy
