14146 127mm Heavy Duty Aluminum Omni Wheel Bearing Rollers features:

The (5 inch) 127mm Omni-directional wheels are unique as they are able to roll freely in two directions. The Omni-direction wheels allow a robot to

 convert from a non-holonomic to a holonomic robot. A non-holonomic robot that uses normal wheels has only 2 out of 3 controllable degrees-of-freedom – 

moving forward/backwards and rotation. Not being able to move side ways makes a robot slower and less efficient in reaching its given goal.
