RWM Caster's 70 Series features extra heavy duty kingpinless caster construction using our patented offset raceway for additional strength. This caster is one of our earliest success stories and is still proven to outperform kingpin design casters in demanding industrial caster applications. This caster series is proudly Made in the USA!

If you don't see what you want, RWM's engineering team can custom design a caster for any application!
Features
Raceway Design: 2-3/4" diameter with 1/2" carbon steel balls. Load and thrust are accommodated by our patented Kingpinless™ design. Precision machined; hardened to 53 Rockwell C. minimum.
Leg Thickness: 1/4" formed steel
Axle: 1/2" bolt and nut. Lubrication - Zerk fitting in axle on 2" wide wheels, 3/4" axle on 2-1/2" and 3" wide wheels
Capacity: 6,000 lbs.
Finish: Laguna Blue powder coat
Wheels: 2" wide wheels are equipped with either 3/4" roller bearing which rotates on a 3/4" hardened and ground spanner, annular bearing, or a delrin/plain wheel bearing. 2-1/2" and 3" wide wheels are equipped with either a 1" I.D. straight roller bearing which rotates on a spanner bushing, 3/4" I.D. tapered bearings that rotate on the axle, or precision ball bearings.
Mounting Plate Size: 4-1/2" x 6-1/2" x 5/16"
Bolt Hole Spacing: 2-7/16" x 4-15/16", slotted to 3- 3/8" x 5-1/4"
Mounting Bolt Diameter: 1/2"
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 70 Series is the perfect solution for:
  • tire manufacturing
  • fixture carts
  • trash gondolas
  • drywall dollies
  • autoclave dollies

To order a rigid caster, change the “S" to “R" in the model number. For example: “70-CIR-0420-R". To order a rig only, omit the blue letters. For example: “70-0420-S". Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative. For approximate weight of our rigid casters, deduct 3.9 pounds.
