Do crankshaft journals wear?

Forged steel crankshaft are made from a single piece of steel and feature built-in oiling grooves to help keep the bearings lubricated and cool. They typically weigh more than cast or billet cranks because of their larger size and weight, but they are less likely to crack or break than cast cranks. Many aftermarket performance parts makers use forged steel cranks because they are more durable than traditional cranks and can provide faster acceleration and higher RPMs. A forged steel crankshaft usually has 3 main bearings located close to the center of the shaft and two rows of small journal bearings that are located on both sides of the shaft to keep the crankshaft properly aligned during operation.
