Kingpinless casters are the industrial standard for heavy duty applications — no central kingpin to wear out under shock load. Forged steel construction, sealed precision bearings, polyurethane on iron wheels rated 1,200 to 3,800 lb per caster. Used on OEM industrial equipment, manufacturing fixtures, dunnage carts, and military equipment that sees 24/7 operation. Stocked at our Mansfield, TX facility.
Kingpinless casters replace the traditional kingpin design with a sealed swivel raceway. Eliminates the #1 wear point on conventional casters — the kingpin nut loosening or breaking under shock load. 2-3x longer service life than conventional designs.
Conventional casters wear out at the kingpin under shock load. Kingpinless removes the kingpin — sealed swivel raceway with hardened precision bearings instead. Significantly longer service life.
1,200 lb (4" wheel) up to 3,800 lb (8" wheel). For higher capacity, see our extreme duty and super duty kingpinless casters.
Polyurethane on iron is standard. Forged steel for extreme abrasion. Phenolic for high-temp. All available in kingpinless configuration.
4 x 4-1/2 plate is the heavy duty kingpinless standard. Use larger plates for larger wheel diameters and capacities.
