76 Series Casters

HEAVY DUTY KINGPINLESS CASTERS

RWM Casters 76 Series industrial casters feature the patented Kingpinless™ caster design. This is the design that RWM patented, and that has proven to be the best solution for demanding heavy duty applications. This is the caster design that all others are copying because it is simply unmatched in extending service life, reducing all possible causes for caster failure.

The 76 Series offers up to 7000 lb. capacity and is available with a wide variety of wheels in 3” width. This caster is designed with beefier legs and extended leads making it an excellent option for towing operation in automotive assembly plants, tire manufacturing and heavy duty industrial applications demanding a superior product. All swivel sections are supplied with a lubrication fitting for field
maintenance. The 76 series is case hardened for extended service life. It will not crack like through hardened or induction hardened construction provided by other caster manufacturers. Our 76 series industrial casters are proudly made in the USA!

To order a rigid caster, change the “S” to “R” in the model number. For example: “75-CIR-1030-R”. To order a rig only, omit the blue letters. For example: “75-1030-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.
