Product Details and Benefits

This Precor stair arm wheel is a small but important mechanical component within the elliptical’s stair arm system. The wheel supports the movement of the arm assembly and helps the mechanism travel as designed during use. Replacing the affected wheel can help address service issues related to a damaged or worn stair arm wheel.

The product is identified as **WP100**. Its brand is **Precor**, and its product category is **Wheels**. The item is listed as the **Precor EFX 635 665 685 Elliptical Stair Arm Wheel**. The SKU and barcode are both **WP100**.

A replacement wheel can help simplify equipment maintenance when the original component no longer meets the needs of the stair arm assembly. Instead of replacing the entire elliptical or a larger assembly, a compatible replacement part allows you to focus on the specific wheel that requires service.
