These industrial casters are designed for low speed manually moved applications only. Foam Filled Pneumatic Wheels have NO air in the tires, thus eliminating the possibility of the wheels ever going flat.
Foam Filled wheels do NOT have any resilience. They provide the same traction and wide footprint of air filled wheels which enables them to roll on grass, dirt and over small pebbles.
Foam Filled Pneumatic Wheels have a higher initial cost than Air Filled Pneumatic Wheels. However, over time, they may prove to cost less because they last longer and avoid down time due to loss of air. Since people tend to load equipment only to the weight they can move easily,
Foam Filled Pneumatic Wheels can lead to higher productivity because they require less effort to move than pneumatics that are under inflated.
