Customized Bearing Assemblies that are Moving the Automotive Industry

With our products in ⅔ of North American vehicles, almost every driver enjoys the benefits of our products each day – without realizing it!

Rolling elements are either balls or rollers. Rollers offer higher load carrying capability (theoretically, a line of contact vs. point of contact for a ball).

Retainers are used to hold rolling elements (balls or rollers) in proper orientation so they do not all bunch together. Typically made from stamped metal or molded plastic.

Bearing cages, also known as bearing separators, are used to hold rolling elements (balls or rollers) in proper orientation so they do not all bunch together. Typically made from stamped metal or molded plastic.

Bearing races, also known as bearing rings, are typically produced using high quality bearing grade chrome steel, which is valued for its superior mechanical properties (tensile strength, hardness, wear resistance).  Precision machining and grinding processes are used to fabricate these components, which must withstand high speeds and loads during operation.

“Roller” implies that the part moves (rolls) when in use.  Generally a roller is acting as a bearing, supporting a load along its outer diameter.

“Pin” is generally used to describe a mechanical component that acts as a fastener to join other parts together in an assembly.  A pin may act as a pivot, hinge, jig, fixture or shaft.  A jig is typically used to hold a work piece in place and/or guide a tool operating on the device.  A pin is often used to locate or hold parts.  Some pins are headed; others are not.
