The brand is \*\*Matrix Fitness\*\*, and the product SKU and barcode are both \*\*MX141\*\*. The part is intended for replacement use rather than general-purpose pulley applications. Match the part number and equipment identification before ordering to make sure it suits your repair.

## Product Details and Benefits

The MX141 is a \*\*serpentine belt tensioner pulley\*\*. In a belt-drive system, the pulley forms part of the tensioner assembly that guides the belt and helps maintain its position during operation. Replacing a worn pulley can support proper belt tracking and help address problems associated with an aging or damaged tensioner component.

A replacement pulley can be useful when the original part shows signs of wear or when maintenance work requires the tensioner pulley to be renewed. Using the correct part number helps reduce the risk of fitting an unsuitable component to the belt system. It also allows a technician or equipment owner to replace the identified pulley without automatically replacing the entire tensioner assembly, provided the remaining components are still suitable for service.

The product information identifies this item specifically as part \*\*MX141\*\*. No material, color, dimensions, quantity, package contents, warranty, or installation instructions are provided in the available listing information.
