47 Series Casters

MEDIUM-DUTY KINGPINLESS CASTERS

Kingpinless casters provide a simple, effective solution for load distribution. Designed for durability, Kingpingless casters facilitate the smooth transport of even the heaviest loads. At RWM, our design teams have developed the 47 Series Caster to withstand the most demanding work environments. In applications where high-impact stresses are common, these casters will deliver uncommon performance and reliability.

Benefits of 47 Series Casters

The design of our 47 Series Casters means that you can use them within higher speed applications. This is because the design distributes the weight over a much larger area. Further, the swivel section facilitates smoother, faster turns, which eases maneuverability and means that the component will require less maintenance as the years go by. Overall, the design makes Kingpinless components ideal for high-speed towing applications where high loads and the need for enhanced turning capacity exceed kingpin designs’ capabilities.

Each of our 47 Series Casters is designed to deliver flawless performance. Contact RWM at 800-634-7704 to discover more about the many benefits of using these solid components for your business.

For a rigid caster, change the “S” to “R” in the model number. For example, “47-UPB-0520-R.” To order rig only, omit the blue letters. For example, “47-0520-S.” For approximate weight of a rigid caster, deduct .7 pounds. Dimensions shown are nominal. If precise dimensions are required, please consult your RWM representative.
