Benefits of Pneumatic Casters

Do a longer wheel life, reduced maintenance, and enhanced shock absorbency sound like something your business could use? If it does, then pneumatic casters are the ideal solution. The foam or air-filled tires of pneumatic casters provide a cushioned ride well suited for industrial applications. They are ideal for use on pavement and on uneven/damaged flooring. They also won’t damage tiles, linoleum, concrete, or other surfaces.

Pneumatic casters will roll over debris and other obstacles with ease. They will help protect your carts and cargo from damage, and they will extend the operational life span of your wheels. Further, the design of pneumatic casters reduces wear and tear, which in turn reduces required maintenance, making these casters a convenient option.

At RWM, our pneumatic casters are designed to deliver superior load cushioning performance. They can be affixed to dollies, maintenance equipment, carts, machinery, and more. This makes them a versatile option that can be used for production, material handling, product distribution, and more. And the additional friction created by the inflated wheel improves ground contact, which increases traction and reduces the possibility of loads tipping and toppling over as the wheel moves across flooring, loading docks, parking lots, etc.
