Kingpin Caster Design Benefits and Drawbacks

Below, we break down the design and the advantages versus disadvantages of kingpin casters.

Kingpin Caster - How Does it Work?

The parts that compose a kingpin caster, or traditional caster, include:

  • Top plate - connects the assembly to your industrial application
  • Kingpin - the central pin in the assembly
  • Upper and lower races - hold the load
  • Upper and lower bearings - allow movement

A pin-based assembly allows the kingpin swivel caster to move freely in all directions. The centralized swivel pin aligns the upper and lower races holding the ball bearings.

Benefits of Kingpin Swivel Casters

The main advantage of a caster with a kingpin is that you can adjust the pin to control the swivel ability as necessary. This feature is helpful if your heavy loads travel through areas with inclines where unexpected movement changes pose the risk of damage. Adjusting the swivel can prevent harm.

You can also adjust the central nut to manage wear patterns over time and extend the kingpin assembly's lifespan. The build of the kingpin caster also allows users to clean the swivel section as needed.

Potential Drawbacks of Kingpin Casters

The primary drawback of the kingpin design is that the pin bears the brunt of the thrust and load action. Over time, the pin will wear down and become more likely to fail. 

These casters are also not ideal for higher speeds or fast cornering. Their maximum speed rating commonly falls between two and three miles per hour, or the walking speed of the average human. Going beyond this rating will cause the pin to shear.

The kingpin vs. kingpinless caster discussion doesn’t end here. Let’s take a closer look at the kingpinless design below.

Kingpinless Caster Design Benefits and Drawbacks

You might be surprised to learn that a kingpin caster and a kingpinless caster have stark differences. Learn more about the kingpinless caster's design elements and the pros and cons of these unique swivel casters.

Kingpinless Swivel Caster - How Does it Work?

The kingpinless design, in contrast to the traditional caster, relies on simplified interlocking races that hold the ball bearings to allow smooth movement. The build involves the following essential parts:

  • Top plate and upper ball race
  • Yoke base with lower race and ball bearings

The bearings handle all the work, evenly spreading the weight of the load without depending on a kingpin.

Benefits of Kingpinless Casters

A kingpinless caster's simplified design allows for a wider, more stable spread of the caster's load. This stability feature enhances load distribution and allows the caster to move at a higher speed.

The improved distribution also allows for heavier caster load ratings while maintaining cost efficiency. The robust assembly can tolerate higher-impact loads while better resisting the wear and tear of daily industrial use.

By eliminating the kingpin, you also reduce the regular maintenance requirements and unwanted adjustments in maneuverability.

Potential Drawbacks of Kingpinless Casters

At this point, you might think there’s a clear winner in the kingpin vs. kingpinless caster debate. However, kingpinless casters have a drawback for some industrial caster applications.

These casters aren’t ideal for applications where your swivels will require adjustment for safe operation in various environments. In some cases, you may be able to install a swivel restrictor device after initial assembly. However, older or worn-down swivel raceways can hamper the efficacy of the installation.

You want to prevent these caster-related problems before they have a chance to occur. You can accomplish that goal by investing in the right caster for each application in your business.
