RWM’s 95 Series caster features the patented Kingpinless™ caster design. This is the design that RWM patented, and that has proven itself to be the best solution for demanding applications. This is the caster design that all others are now copying because it is simply unmatched in extending service life, reducing all possible causes for caster failure. The 95 Series offers a capacity up to 20,000 pounds with a wide variety of heavy duty wheels to maximize capacity.

Our 95 Series Casters are proudly made in the USA! Log in below to download CAD drawings of this caster.

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
The 95 Series typical applications include dollies, utility carts, tow line and platform trucks. It is also ideal for: tow lines, shock load applications and abusive conditions, production line dollies & 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 countless other heavy duty applications.
