Product information "Main bearings BMW M30 S38 ACL Aluglide"
ACL Aluglide main bearings for BMW M30, M88, M106 and S38
STD 0.00mm
ACL Aluglide bearings are precision manufactured to a wall thickness tolerance of ±.00026″ giving the engine builder close control of vertical oil clearance. For performance engines the extra build quality provided by tight clearance control can make all the difference.
Bearing Construction:
- 1 - Steel strip onto which is added powdered copper-lead-tin metal alloy. The strip is sintered and compressed to bond the alloy to the steel backing.
- 2 - ACL sintered copper-lead-tin alloys provide a tough structure capable both of resisting high compressive loads and providing excellent adaptability.
- 3 - A lead-tin-copper overlay is applied to copper-lead-tin bearings produced by ACL. It is necessary however, to include a nickel intermediate layer (barrier plate or dam) to preserve the optimum metallurgy of the overlay under all operating conditions. ACL’s superior quality construction and control in electroplating eliminate potential overlay flaking.
- 4 - The lead-tin-copper overlay used by ACL consists of approximately 90% lead, 9% tin and 1% copper. Overlay thicknesses are nominally .0005″ – .0007″ for most automotive applications.
