Details
- Full (180 degree) grooved uppers with matching partial groove in lowers.
- Reduces interruption to big end oil supply.
- Tapered groove run-out.
- Smooths big end supply cut-off avoiding pressure pulsing and cavitation.
- 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.
- Assists in the formation of hydrodynamic oil film.
- Accommodate larger fillet radii on performance crankshafts.
