85 Series Casters

HEAVY DUTY KINGPINLESS CASTERS

RWM’s 85 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 85 Series offers a capacity up to 10,000 pounds and is available with wheels up to 5” wide for higher capacity ratings. This caster is built to take the punishment experienced in high shock and impact loads.

To order a rigid caster, change the “S” to “R” in the model number. For example: “85-CIR-0840-R”. To order a rig only, omit the blue letters. For example: “85-0840-S”. Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative. For approximate weight of our rigid caster, deduct 3.9 pounds.
