Kingpinless Casters
Compared to the traditional swivel section, a kingpinless swivel section is much simpler in design. It is constructed of a top plate with a forged inner race, an outer race to which the wheel arms are attached. The ball bearings rest between the two pieces. This design completely eliminates the need for a kingpin, as the name kingpinless implies.
As depicted in the illustration to the right, the construction is straightforward. Kingpinless casters provide an excellent alternative to traditional swivel casters in applications where the casters are subjected to high impact especially while transportation.
The technical advantage of kingpinless casters make them an excellent choice for many applications. Removing the kingpin eliminates the common problems associated with traditional kingpinned casters. Obviously, though, it isn’t quite that simple, the reason for the enhanced durability and performance lies in load distribution.
Consider the towing application, using a traditional swivel caster can lead to shearing of the kingpin and catastrophic failure of the caster. By utilizing this design, the load that is placed on the caster is distributed over a greater surface area. A kingpin, on average is about 5/8” in diameter, giving roughly a 2” circumference about which the load is distributed. Comparing that to a kingpinless swivel section which as a diameter of about 2”, giving a circumference of over 6”, and the difference is translated in its performance and durability.
The same applies to the shock loading scenario. As the load is impacting the caster, or the caster to the floor, the greater impact area gained by the kingpinless design allows for the caster to absorb more force without failure. Beyond a technical aspect of greater resistance to abuse and better performance, kingpinless casters offer a highly competitive and efficient alternative to traditional towing casters. The use of common ball bearings as opposed to a sealed precision ball or a tapered bearing makes the price highly attractive, without sacrificing capacity or durability.
Kingpinless medium duty casters
Polyurethane balloon type tread fully moulded over cast iron insert and housed in forged and fabricated steel caster, this type of caster wheels are ideal for medium duty applications. The casters made of forged steel brackets, constituting of a single bearing raceway assembly and are free of kingpin. These type of caster assembly increases the life and durability of casters, and can be used in applications involving mechanical towing. These wheels are suitable for epoxy flooring.
Kingpinless heavy duty casters
Polyurethane flat tread over cast iron insert and housed in forged and fabricated steel caster, this type of caster wheels are ideal for heavy duty applications. The casters made of forged steel brackets, constituting of a single bearing raceway assembly and are free of kingpin. These type of caster assembly increases the life and durability of casters, and can be used in applications involving mechanical towing. These wheels are suitable for epoxy flooring.
