53 Series Casters

HEAVY DUTY CASTERS

RWM Caster’s 53 Series features thicker legs and a 3/4” diameter axle that improves on our very popular 52 series. This caster is designed to stand up to most heavy duty industrial caster applications and is proudly Made in the U.S.A. If you don’t see what you want, let our engineering team custom design a caster for your individual application.

FEATURES
Swivel Section Cold formed top plate, yoke and button are all heat treated to prevent brinelling, improve swivel action and increase service life. Both load and thrust bearings are hardened and ground and raceway bearings rotate on hardened raceways. Top plate and legs are 1/4” steel. Legs are formed for increased strength and continuously welded to yoke. All swivel sections are equipped with a lubrication fitting for field maintenance. RWM lubricates all swivel sections prior to shipment.
Kingpin 3/4” bolt and lock nut for increased swivel section strength
Capacity Up to1800 lbs.
Axle 3/4” diameter axle
Finish Zinc plated to protect against corrosion
Wheels Wheels are available with either 1” I.D. diameter straight roller bearings which rotate on a 1” O.D. hardened and ground spanner bushing, or 3/4” I.D. tapered bearing on a 3/4” axle. The tapered bearing configuration is highly recommended for high speed and side thrust applications.

To order a rigid caster, change the “S” to “R” in the model number. For example : “53-CIR-0825-R”. To order a rig only, omit the blue letters. For example: “53-0825-S”. Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative. For approximate weight of our rigid casters, deduct 1.8 pounds.
