Our 20-inch by 5-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 heavy loads, they offer durability and longevity, thanks to the securely bonded mold-on rubber tread and solid wheel core. While polyurethane wheels typically offer higher weight capacities, these rubber wheels carry loads up to 3000 lbs.
