What is Kingpinless?

The Kingpinless design differ from the traditional kingpin style casters.

Kingpin casters are the most common caster throughout the industry. It uses a central kingpin to hold the swivel raceways and ball bearings together. The biggest problem with this design is when the caster failure due to overloading and shock loads which can cause the kingpin (commonly referred to as a nut and bolt) to stretch or break. The solution for these common issues is kingpinless design. 

Kingpinless casters have eliminated the weakest link of the kingpin style caster. This is achieved by using a hardened steel inner and outer raceway and distributing the load to a single row of hardened ball bearings.  Some of the benefits of a kingpinless style caster include:

  • Greater impact resistance
  • Higher load capacity
  • Longer service life
