A blend of characteristics to provide high strength and excellent seizure resistance.
No flash plating is applied to further improve bearing retention and maximise heat transfer.
Improved bearing retention from higher radial contact pressure.
Locks the bearing into the housing.
More effective heat dissipation through improved thermal transfer.
Definition: Gradual reduction in wall thickness between the crown and parting line.
ACL Race Series performance engine bearings feature increased eccentricity to improve shape adaptation to compensate for bore distortion at high speed operation.
