4"X2" Polyurethane on Iron Wheel Rigid Caster - 800 Lbs Capacity

Polyurethane on iron caster wheels offer more floor protection, non-marking treads, quieter rolling, & smoother rides compared to steel or phenolic wheels while still providing comparable load capacities. These polyurethane on iron wheels feature a crowned tread for easier rolling and turning, and also have a heavier core compared to the poly on iron wheels with red or green treads. These wheels can be used in most applications, but are not recommended for hot or cold applications, or when left in water for most of their use.
