About Casters and Wheels

The rounded tread on these wheels allows them to turn more easily than flat-tread wheels. They have a hard core for strength and a polyurethane tread that combines the abrasion resistance of plastic with the shock-absorbing qualities of rubber. Use them on smooth or rough floors and in areas with debris. Ball bearings in the wheel provide easy rolling.

Sealed bearings are completely sealed for the best protection against dust and debris.

Also known as twin-wheel casters, these lightweight and economical casters are often used on displays. Friction on their stem's grip ring holds them in place. The nylon wheels are impact and wear resistant. Wheels ride directly on the axle rather than on bearings, making them an economical choice for equipment not frequently moved. They work well on smooth surfaces.

Casters with a grip-neck stem include a mounting socket that can be tapped into a wood leg or post to securely hold the stem.

Lightly step on casters with a foot-pedal brake to stop movement.

Polyurethane wheels combine the abrasion resistance of plastic with the shock-absorbing qualities of rubber. They can be used on smooth and rough floors and in areas with debris. Wheels ride directly on the axle rather than on bearings, making them an economical choice for equipment not frequently moved.

Stems with grip ring press-fit into tubing, sockets, and drilled holes—friction holds them in place.

Casters with grip-neck stem include a mounting socket that can be tapped into a wood leg or post to securely hold the stem.

Casters with wheel brake apply pressure to the wheel to stop movement with a press of the foot pedal.
