52 Series Casters
Medium Duty Casters
RWM Caster’s 52 Series is manufactured from cold formed steel. This series is highly recommended for use in medium duty industrial caster applications.
Features
| Swivel Section | Cold formed top plate, yoke and button are all heat treated to prevent brinelling, improve swivel action and increase service life. Load and thrust bearings are hardened and ground and rotate on hardened raceways. Top plate and legs are 1/4″ steel, legs 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. |
