Steel-Hub Pneumatic Wheels
Block
Tread Pattern
These wheels consist of an air-filled rubber tire on a steel rim and are among the quietest, most shock-absorbing wheels available.
Tires with an inner tube are more puncture resistant than tubeless tires. Ball bearings are the easiest to roll.
Center-mount hubs are symmetrical for equal clearance on both sides of the wheel.
Two-piece rims consist of two pieces bolted together so the wheels can be quickly repaired or replaced.

Pneumatic Casters with Rubber Wheels
The air-filled wheels on these casters absorb shock to protect your load even on rough surfaces.
Ball bearings are the easiest to roll. Swivel casters with double-ball bearings have the smoothest swiveling.
