A bearing is a crucial element of any mechanism where rotational or linear movement takes place, and a vehicle is no exception. Bearings enable parts of these mechanisms spin and roll smoothly and quietly with minimal friction. Bearings must efficiently handle a load, basically, support a radial (weight) and/or thrust (cornering force) load. National bearings effectively reduce friction and handle a load to provide the performance you really can depend on. Quality certified steel this bearing is made of and computer controlled heat treatment processes utilized in manufacture guarantee its reliable performance and maximum durability. This part is built to OE specifications to ensure factory-like fit, function, and reliability.
