Equally important is the location and sequence of the hooks. Rely on your authorized dealer to help you select the hooks best suited to your operation. These heavy duty arm support wheels are designed to complement a new generation of high-tech floor coverings. Made with a new wear-resistant material, the arm support wheels have a 33 percent greater width than previous versions, and an increased depth of hardness for longer service life. The sprocket is made of high quality, tractor-class ductile iron.
Teeth are induction hardened for a uniform, consistent surface hardness.
The outer case is hardened to a specific depth to create resistance to micro fractures and embrittlement. All raised surfaces are machined smooth to reduce wear and increase service life. In addition to using conventional oil seals to keep out dust and dirt, these sprocket assemblies also use mechanical Labyrinth Seals machined into the sprocket body. Partial replacement of wearing parts is false economy. Do not allow the re-use of old sprocket retainers or other worn components.
