Bearings Definition of the Day: Carburize

Carburize, in its most literal sense, means to unite with carbon.
Carburizing is a type of case hardening that causes carbon atoms from
a carbonaceous solid (“pack carburizing”) liquid (“liquid carburizing”) or gas
(“gas or vacuum carburizing”) to be absorbed by the metal. Carbon atoms
diffuse into the metal to form a high-carbon, high-hardness zone.
Typically, carburizing increases surface hardness by 200-600%, while
also improving wear and fatigue resistance. Hartford Technologies’
low carbon steel balls and components for low carbon steel bearings
(e.g. races in ball bearings or washers in thrust bearings) are carburized
to provide this increased performance.
