A tough, puncture-resistant tread surrounds a nonpressurized pocket of air so these wheels absorb shock to cushion like pneumatic wheels but won't go flat. Use them on smooth or rough surfaces.

Shielded ball bearings in the wheel provide easy rolling and protect from dust and debris.

Swivel casters have double-ball bearings for the smoothest swiveling.

Also known as semi-pneumatic wheels, these have a puncture-resistant tread and a pocket of nonpressurized air that provides additional cushion without inflation.

Roller bearings provide smooth rolling. Ball bearings are the easiest to roll.

Center-mount hubs are symmetrical for equal clearance on both sides of the wheel. Side-mount hubs are offset for extra clearance between the wheel and your equipment.

Lug-fit rims have a series of indentations that line up with the tire’s lugs to lock the tire in place so it won’t slip on the rim.
