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.

Case Hardened Kingpinless Casters — for Strength You Can Count On

The case hardened 76 Series caster provides maximum service life, making this an extremely cost-effective product. These Kingpinless metal heavy-duty casters eliminate cracking risks, unlike the often-unreliable through-hardened or induction-hardened casters that other manufacturers offer.

  • Case hardening, also called surface hardening or carburizing, is a superior process used here at RWM. Case hardening is a thermochemical method that reinforces metal casters by adding a layer of another, more durable metal alloy. This increases hardness on the outside, while the inner, low-carbon core remains slightly softer, to counteract any brittleness. This makes our casters stand up to heavy loads and long-term use without cracking.
  • Through hardening is the process of using a rapidly heating and quenching (cooling in water or oil) metal to increase steel hardness. This process can leave the metal caster somewhat brittle, and prone to breaking under stress, unfortunately.
  • Induction hardening exposes metal caster parts to electromagnetic energy creating an alternating current in the caster component. This heats the metal, but typically hardens only a certain area, leaving other areas somewhat weaker and vulnerable to cracking and breaking.

When you need case-hardened, heavy-duty Kingpinless casters, choose the 76 Series from RWM Casters! Call us at 800-634-7704 to place your order today.
