Steel-Hub Pneumatic Wheels

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.
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.
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.
Casters with wheel brake apply pressure to the wheel to stop movement with a press of the foot pedal.
Forged-steel frames are more durable than formed-steel and stamped-steel frames.
Ball bearings are the easiest to roll.
Swivel casters with ball/tapered roller bearings provide easy swiveling and good impact resistance. Swivel casters with double-ball bearings have the smoothest swiveling.
Shielded bearings protect the bearing from dust and debris. Sealed bearings are completely sealed for the best protection against dust and debris.

Flat-Free Casters with Polyurethane Wheels
The solid rubber wheels on these casters cushion as well as pneumatic wheels but won't go flat. Use them on smooth or rough floors and in areas with debris.
Ball bearings in the wheel provide easy rolling.
Swivel casters have double-ball bearings for the smoothest swiveling.
