What are Kingpin Casters?

Kingpin casters are widely used throughout various industries to give wheels a swiveling action. They are a strong, economical option for light- to medium-duty applications. Their load-bearing capabilities come from a central Kingpin, which holds the swivel raceways and ball bearings together. This Kingpin takes the form of a rivet or bolt, available in various sizes based on the needed capacity.

Most Kingpin casters are appropriate for bearing loads less than 2,000 lbs. Suitable applications should involve minimal impacts and infrequent towing. For heavy-duty uses with higher load-bearing capacities, impact resistance, and towing capabilities, you need Kingpinless casters. RWM Casters is the original inventor of this technology, making our Kingpinless casters the best on the market.

Benefits of Kingpin Casters

If you’re searching for industrial swivel casters, consider the Kingpin technology before you look into other options. The benefits of this design include:

  • Affordability: Because they are designed for light- to medium-duty applications, Kingpin casters are more affordable than heavy-duty options. If your load-bearing needs are less than 2,000 lbs, you could save by choosing Kingpin casters.
  • Adjustability: The threaded Kingpin design, in particular, allows you to tighten the rivet or bolt in instances when you want to decrease the swivel action of your casters without the need to take apart the entire assembly. This accessibility also makes Kingpin casters faster and easier to clean.
  • Long lifespan: The Kingpin design makes it possible to adjust the nut as the swivel section wears out, prolonging the life of the caster. There is no way to make this adjustment with a Kingpinless caster.

Types of Kingpin Casters

There is a tremendous array of Kingpin casters available today. Some have unique features, such as the economical locking stem caster, which allows users to brake at various positions while swiveling simultaneously.

There are also our Freedom® Series casters, which offer the benefit of being maintenance-free with no lubrication required. Our pneumatic stem casters are another unique option designed for applications requiring a cushioned ride.
