Wheels range from soft rubber that absorbs shock while providing good traction on rough surfaces, to hard, impact‐resistant rubber that rolls easily on smooth surfaces.

Also known as twin‐wheel casters, these lightweight and economical casters are often used on furniture and displays.

Polyurethane wheels combine the abrasion resistance of plastic with the shock-absorbing qualities of rubber. They can be used on smooth or rough floors and in areas with debris.

Often used on furniture, the hood covers the wheel for a more finished appearance.

The most durable plastic wheel, the nylon wheels on these casters are impact and wear resistant. They work well on smooth surfaces. The wheels dissipate static to protect sensitive electronic equipment from electrostatic discharge.
