HEAVY-DUTY KINGPINLESS CASTERS The 76 Series Kingpinless caster easily handles heavy loads, with up to 7000 lb. capacity, and we offer many different wheel configurations in 3” width to meet your needs. This built-to-last metal caster is designed with extended leads and stronger, thicker legs that really pull their weight under pressure. Swivel components come with lubricated fittings for simple maintenance in the field. Get a 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 rapid 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.
