These wheels have rollers that rotate around the wheel core to allow movement in any direction.

Wheels with a plain bore rotate freely around an axle or shaft. Wheels with two or three wheels have increased surface area, so they are stable, smooth, and less likely to slip than single wheels.

Polyurethane wheels combine the abrasion resistance of plastic with the shock-absorbing qualities of rubber.
