Product description

The spider assembly is a critical structural casting that supports the turntable on Coats rim-clamp tire changers. This heavy-duty component straddles the clamping cylinder and provides the necessary foundation for the wheel clamping mechanisms. Because it carries the full load of the tire and wheel during the mounting process, it is engineered for extreme rigidity and durability. Cracks or warping in the spider casting can lead to turntable instability, poor clamping force, and potential safety hazards. Replacing a damaged spider assembly restores the precision and structural integrity of your machine, ensuring safe and accurate wheel service for years to come.
