Dual wheel rigid casters top plates utilize a larger surface area on many sizes to accommodate the width of the wheels and leg spacing required. These casters will utilize special top plates combining the adapter plate and mounting plate together in one plasma cut component which look like this (DOWNLOAD). Dimensions stated as top plate size on these pages are the general outside dimensions of the standard plate when these tabs are not necessary such as on small sizes. Please contact the factory for specifics or if any questions in regards to the items you are looking at.
Features
Raceway Design: Patented Kingpinless™ single ball bearing precision machined raceway hardened to 53 Rockwell C minimum. Swivel section features a 2-3/8" diameter raceway with 3/8" ball bearings. The notched yoke is standard. All swivel sections are supplied with a lubrication fitting for field maintenance.
Capacity: 2,000 lbs.
Axle: 1/2" diameter with lubrication fitting and lock nut
Finish: Zinc plated to protect from corrosion
Wheels: All wheels are 1-1/2" wide with a 3/4" I.D. roller bearing which rotates on a single 3/4" O.D. spanner bushing for ease of rollability. All bearings are pre-lubricated.
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"
Leg Thickness: 1/4" formed steel
Options
CWB: Cam Wheel Brake
DSL: Demountable Swivel Lock

LT: Low Temperature Lubrication
SL: Swivel Lock
SR: Sealed Swivel Raceway
TG: Thread Guard
HTP: High Temperature Paint (add 2" wide rig options)
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

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.
