King Bearings developed the HP Series, featuring the Alecular bi-metal composite. The Alecular technology made to better resist extrusion & material migration under high load for short duration or medium load for long duration, particularly in applications such as drag racing, monster truck and tractor pull competitions.
Commonly use for
applications requiring a harder than Babbitt top layer to better resist extrusion & material migration (drag racing, monster truck, tractor pull). Also for all other applications using nodular cast iron crankshafts
