Features
Raceway Design: Patented Kingpinless™ single ball bearing precision machined raceway hardened to 53 Rockwell C. minimum. 7" diameter raceway with 3/4" diameter ball bearings.
Capacity: 40,000 lbs.
Axle: 1-1/4" bolt with rotation prevent lug on leg and slotted nut adjustment
Finish: Laguna Blue paint
Wheels: Wheels are either 4", 5" or 6" wide depending upon diameter and wheel type. Roller bearing wheels are equipped with a bearing which rotates on hardened and ground spanners. Tapered bearing wheels have a 1-1/4" I.D. tapered bearing which rotate directly on a 1- 1/4" axle. All wheels have lubrication fittings.

Benefits of Kingpinless Raceway
Our patented offset precision-machined raceway exerts radial force evenly where there is full contact between the ball bearing and the raceway. RWM's unique design adds more mass at key points. This, plus more thorough heat treatment, provides additional strength and combats brinelling into the core material.

The Result:
  • No direct "hammering" forces on the intersections of the raceways
  • Vastly reduced raceway wear
  • Elimination of the "pull apart" forces of stress in the swivel section
  • Smoother swiveling action
  • High maneuverability
  • Longer service life
  • Less maintenance
  • Extra impact resistance
  • High radial force absorption

Applications
Dual wheel casters offer high weight capacities with minimal overall heights, better load distribution, floor protection and mobility than single wheel casters. This is a result of spreading the weight over a wider floor area while offering wheel differential action, resulting in less friction between the wheels and the floor, requiring less effort for the caster to swivel. Dual wheel casters are ideal for tow lines, shock load applications and abusive conditions, production line dollies and trucks used in various industries including but not limited to boat and ship molding and building, automotive, aerospace, metal fabricating, metal forging, heavy machinery and equipment, military equipment, mobile homes, etc. tractor pulled trailers, extreme duty platform trucks and material handling carts, air cargo and ground support equipment, storage tanks, gantries and heavy duty processing equipment, coliseum and gymnasium equipment, shipping / receiving carts, warehousing and freight terminal dollies and carts, and other extra heavy duty applications.
