Description

PRECISION MANUFACTURING
ACL Race Series performance engine bearings are manufactured to exacting tolerances. Micron tolerance machining supported by precision measurement systems delivers consistent accuracy to key characteristics like wall thickness and crush. This ensures reliable fit and helps maintain consistent clearances.

BEARING MATERIAL ENHANCEMENTS
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.

Crush increased for:
- Improved bearing retention from higher radial contact pressure. Locks the bearing into the housing.
- More effective heat dissipation through improved thermal transfer.

Bearing Eccentricity:
- 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.

Main Bearings with Extended Grooves
- Full (180°) 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.

Enlarged ID Chamfers
- Accommodate larger fillet radii on performance crankshafts
