We feature 3 different pneumatic or pneumatic type casters. We have the traditional industrial Pneumatic Casters with air filled pneumatic wheels. All of these industrial casters are designed for low speed manually moved applications only. Air filled pneumatic wheels provide a cushioned ride, shock absorption and quiet operation. Pneumatic casters are suited for moving fragile or delicate cargo where caster overall height is not critical. These types of casters are the best choice for use outdoors over rough surfaces or on grass.
These wheels with black tires do not mark the floor as long as the wheel is allowed to roll. Changing directions without allowing a swivel caster to turn gradually around, or dragging a black rubber wheel sideways, can mark some floors.
If you consider maintaining the proper air pressure in a pneumatic wheel a maintenance chore, then consider THESE Flat Free Casters. Wheels are made with Microcellular Polyurethane Foam for a great ride and care free operation! Durable 2 piece bolt together steel hub assembly. Hub assembly comes standard with zinc plating. Tire Color: Black - Available ONLY in 6 inch.
