4" CAST IRON W/ HOLE FIXED

This 4″ cast-iron-hub fixed caster is engineered for maximum weight capacity and unyielding straight-line travel in foundry, machining, and heavy manufacturing settings. The unbreakable cast-iron core provides high structural rigidity under extreme static and dynamic loads.

Its rigid orientation keeps heavy machinery and industrial transfer carts moving predictably down designated floor tracks. It is completely immune to oil, grease, high heat, and sharp floor debris commonly found in heavy shop environments.
