M.D. Spares are proud to be an authorised ACL Race Series stockist.
The ACL Race Series is manufactured in Australia by ACL Bearing Company Pty Ltd. Their range of performance engine bearings are manufactured to exacting tolerances with particular attention paid to wall thickness accuracy. This ensures reliable fit and helps maintain consistent clearances.
Please be aware the we rely and draw on ACL stock ex-factory as required for many part numbers listed. Please enquire with our online sales team for current stock availability.
ACL Race Series Performance Bearings Feature:
~ 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.
~ BEARING DESIGN ENHANCEMENTS ~ Crush increased for: Improved retention from higher level radial contact pressure. Locks the bearing into the housing. More effective heat dissipation through improved thermal transfer.
Bearing Eccentricity: Gradual reduction in wall thickness between the crown and parting line. Race Series performance engine bearings feature increased eccentricity to increase 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 degrees) 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.
The ACL Race Series performance engine bearings range includes Main Bearings, Camshaft Bearings and Conrod Bearings. You will also find available some Thrustwasher Sets from the general ACL range.
