The thick, solid rubber or polyurethane foam treads provide the cushioned ride of an air-filled pneumatic wheel without the possibility of a flat tire.

Center Hub Mount—Center-mount hubs are symmetrical for equal clearance on both sides of the wheel.

Side Hub Mount—Side-mount hubs are offset for extra clearance between the wheel and your equipment.

Roller Bearings—Roller bearings provide smooth rolling.

Ball Bearings—Ball bearings are the easiest to roll.

Rubber—Rubber wheels are quiet, shock absorbing, and provide good traction on rough surfaces.

Polyurethane Foam—Polyurethane foam wheels are lightweight and water- and UV resistant.

Polyurethane Foam Wheel/Tread Filler—Polyurethane foam-filled wheels are lighter than solid rubber wheels.

Lug-Fit Rim—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.

Flat-Free Casters with Rubber 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 surfaces.

Wheels either have sleeve or ball bearings. Sleeve bearings prevent wear to the wheel bore. Ball bearings in the wheel provide easy rolling. Shielded ball bearings also resist dust and debris.
