Fast answer: Kingpinless casters eliminate the central rivet that typically fails under heavy shock and side-load. In high-cycle industrial environments, kingpinless construction dramatically improves durability and service life.
Why Standard Kingpins Fail
- Rivet deformation under impact loading
- Metal fatigue from directional changes
- Side-load bending stress
- High-cycle industrial use
If your application involves frequent direction changes or heavy shock, a standard kingpin design is a common failure point.
How Kingpinless Construction Works
Kingpinless casters use precision-machined raceways instead of a single central rivet. This distributes load across the entire swivel assembly, dramatically increasing structural strength.
When Kingpinless Is Required
- Automotive manufacturing plants
- Steel and metal fabrication facilities
- Heavy warehouse tow lines
- High-cycle industrial carts
Kingpin vs Kingpinless Comparison
