Product Details and Benefits
This product is a Precor stair arm wheel for elliptical equipment. It belongs to the wheel category and carries the part number and SKU **WP91**. The product is listed for use with the **Precor EFX 536i and EFX 532i elliptical machines**.
The wheel forms part of the stair arm mechanism. As the machine operates, the stair arms move through their designed path, and the wheel supports that assembly. A replacement wheel may help address problems caused by a missing, damaged, or worn original component.
Using the correct replacement part matters because elliptical machines use model-specific assemblies. The WP91 wheel gives owners, fitness centers, service technicians, and equipment maintenance teams a clearly identified part for servicing compatible Precor machines. Replacing the affected wheel can help avoid leaving the equipment out of service while waiting for a complete stair arm assembly or replacing the entire machine.
