Omni-Directional Wheels
The angled rollers on these wheels allow vehicles to move forward, backward, sideways, and turn in place when each wheel is used with an independent drive. Often used on automated vehicles and in robotics, they are also known as mecanum wheels. A left and a right wheel must be paired together to use all of the movement combinations.
Use hubs to connect the wheel to a shaft.

Impact-Resistant Polyurethane Wheels
These wheels have a webbed tread that flexes to absorb shock and tapered roller bearings to withstand both downward and side force. They have a polyurethane tread for abrasion resistance with an iron core for strength. Use them on smooth or rough floors and in areas with debris.
