American Roller Bearing Company primarily makes heavy duty industrial class bearings that are used in various industries in the
US and around the world. The various types are listed by the links to the left. Not only must our bearings provide long in-service life from a rolling fatigue criterion, but they must also hold together structurally from impacts, overloads and occasional high speed excursions. The design of every bearing has been optimized to this end. Years of experience have shown the need for a proper balance between rolling element diameter and raceway thickness. Also considered is the length of the roller to its diameter and the thickness of any flanges on the races. Furthermore, the number of rolling elements has to be balanced with the thickness of the cage webs to insure the cage is structurally sound. All of our “Standard” bearings conform in size and tolerance to either ABMA or ISO standards. The size ranges for our various types of bearings are shown at the bottom of this page.
A critical aspect of any bearing is the choice of material and the proper heat treating of the three major bearing components: 1. Inner Race (Cone), 2. Outer Race (Cup) and 3. Rolling Element. (Ball or Roller). All of these components are made from various bearing quality steels that are commercially available, and their heat treating processes have been proven over the years. All aspects of the heat-treating process are closely monitored and recorded in order to insure that each component has the proper hardness and toughness.
After heat treating, the components go through several grinding stages until they are finished. Most of our grinders are computer controlled, allowing for much greater accuracy and consistency than previously obtained. For the user, this means a greater fatigue and service life.
Quality Control monitors all aspects of the production process insuring that each bearing sold will perform as expected, if not better. We are registered as an ISO 9001 manufacturer.
