Metal Structure : Tri-metal copper lead.

Race Type: Circle track, Off-road, off-shore, others that require steel crankshafts.

Engine requirements: High load – Long Duration.

HIGHER LOAD CAPACITY
The only bearing with load capacity of 17,000psi in the intermediate and 10,200psi in the overlay
BETTER FATIGUE RESISTANCE
The only bearing that goes through a hardening process creating a black fatigue resistance shield, which makes the overlay 24% stronger than any other bearing (11.5hv vs 14.5hv)
MORE ACCURACY
The only bearings with wall thickness variation of ±.0001” as a standard in comparison to ±0.00025”.
MORE CONSISTENCY
from bearing to bearing, requiring less adjustment during assembly
ONE SET FITMENT
The only bearings that don’t require you to buy multiple sets to achieve desired oil clearance
