RWM Caster manufactures the 47 Series as our lightest duty Kingpinless™ caster series. The 47 Series Caster is excellent in demanding applications requiring a product that will withstand shock, continuous use and abusive conditions. This medium duty series features our petented offset raceway for additional strength and is proudly Made in the U.S.A.
Features
Raceway Design: Patented Kingpinless™ single ball bearing precision machined raceway hardened to 53 Rockwell C. minimum. Swivel section features 2 1/8" diameter raceway with 1/4" ball bearings.
Swivel Section: All swivel sections are supplied with a lubrication fitting for field maintenance. Notched yokes are standard.
Capacity:1500lbs.
Leg Thickness: 1/4" formed steel
Axle:1/2" bolt and locking nut drilled with lube fitting
Finish: Zinc plated to protect against corrosion
Mounting Plate Size: 4" x 4-1/2" x 1/4"
Bolt Hole Spacing: 2-5/8" x 3-5/8" slotted to 3" x 3"
Mounting Bolt Diameter:3/8"

Benefits of Kingpinless™ Raceway
Benefits of Kingpinless™ RacewayOur 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
