Hamilton® Poly-Soft™ Wheel 6 x 2 - 1/2" Ball Bearing W-620-SPB-1/2

This poly-soft wheel is formulated for a quieter operation and greater resistance to foreign objects and debris. As the name implies wheel tread hardness measures 82-85 durometer. The livelier material cushions the load thereby reducing vibration on the load resulting in a quieter ride and less wear and tear on the caster and cargo. In addition the new urethane has been engineered to repel steel chips nuts bolts pins etc. And takes on "super ball" properties that offer an energized wheel.
