KINGPINLESS CASTERS

Kingpinless Casters

Kingpinless caster designs remove the kingpin (a common failure point in traditional swivels) and use precision raceways to handle shock, side load, and continuous-duty service with higher reliability.

Best for
Impact, shock loads, continuous use, towline service
Why engineers spec it
Reduces failure risk vs. kingpin swivel assemblies
Common buyers
OEM, MRO, manufacturing, maintenance teams
Selection focus
Load per caster, floor condition, duty cycle, towing

Engineering guidance

What “kingpinless” means (and why it matters)

Standard swivel casters use a kingpin to hold the swivel bearing stack together. Under repeated shock, towing, or side loading, the kingpin can loosen or fail. Kingpinless casters remove that point of failure by using precision raceways and a stronger swivel architecture.

Where kingpinless casters are the correct spec
  • Towline / tugger trains and continuous towing paths
  • Heavy carts on floor seams, joints, and transitions
  • Abusive service: impacts, side loading, frequent direction changes
  • High-duty-cycle manufacturing and material handling
When a standard kingpin caster is enough

If the application is controlled (smooth floors, minimal impacts, no towing, lighter duty cycles), a standard kingpin swivel may be more cost-effective. Use kingpinless when failure risk or downtime cost matters.

Procurement checklist (what to confirm before ordering)
  • Total loaded weight and required safety factor
  • Duty cycle: intermittent vs. continuous movement
  • Towing vs. manual push
  • Floor condition (seams, debris, rough concrete)
  • Wheel material for floor + load (PU, rubber, steel, etc.)
