Kingpinless Casters


At Barron Equipment  and Overhead Doors, we have some of the top maintenance-free, high quality, heavy duty casters on the market. Out of this variety of high-capacity casters, our Kingpinless casters are our most popular. With a capacity range of 650 lbs to 1,250 lbs, these rigid and swivel industrial casters offer a great option for manufacturing applications.

What is Kingpinless?

The Kingpinless caster design differs 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 fails due to overloading and shock loads, which can cause the kingpin (commonly referred to as a nut and bolt) to stretch and/or break. The solution for these common issues is the 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.
