125 Series Casters

ULTRA HEAVY-DUTY KINGPINLESS CASTERS

RWM’s 125 Series 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 and reducing all possible causes for caster failure. The 125 Series offers capacity up to 40,000 pounds. Typical applications include ground support equipment, die carts, and aircraft engine stands. Leg thickness of 1/2” adds extra strength and durability. All swivel sections are supplied with a lubrication fitting for field maintenance.

To order a rigid caster, change the “S” to “R” in the model number. For example: “125-CIR-0840-R”. To order rig only, omit the blue letters. For example: “125-0840-S”. Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative.For approximate weight of our rigid casters, deduct 12.5 pounds per item.
