This 8-inch by 3-inch Mold-On Rubber Caster Wheel combines the strength and resilience of rubber with a robust wheel core for exceptional performance. With superior traction, shock absorption, and non-marking properties, these caster wheels provide smooth and controlled movement while protecting floors. Being softer than poly wheels, mold-on rubber wheels absorb shock better, and also provide a more cost effective alternative for AGV and Conveyor wheels. Engineered to withstand heavier, and thrust loading, they offer durability and longevity, thanks to the precision tapered ball bearing, the securely bonded mold-on rubber tread and the solid wheel core. While polyurethane wheels typically offer higher weight capacities, these rubber wheels carry loads up to 850 lbs.
