ACL Bearings Standard Main Bearing Set with Aluglide Coating

ACL Bearings Standard Main Bearing Sets with Aluglide coating are direct-replacement crankshaft main bearings for engine rebuilds. They are made from ACL's Aluglide bi-metal alloy, which combines aluminum, tin and silicon over a steel backing. The standard size is intended for use with a stock-size crankshaft. They suit OEM-style rebuilds and general-purpose street use.

Key Features:

• Aluglide aluminum-tin-silicon alloy: This is a lead-free, bi-metal bearing material developed for OEM engines and suited to replacement use.
• Steel backing: The steel backing is combined with the alloy for strength, anti-seizure, anti-wear, embeddability and corrosion resistance.
• Strip cast microstructure: It gives a strong bond between the aluminum layer and the steel backing. This helps the bearing carry load over long service intervals.
• Hard, wear-resistant surface: The tough alloy surface reduces wear and helps limit abrasion of the crankshaft journal.
• Standard size: These sets are for crankshafts that are still at stock journal size.
• Australian-developed and made: ACL Bearing Company produces them in Tasmania. ACL is an original equipment supplier.

Fresh main bearings help restore proper oil clearance and support smooth, reliable engine operation after a rebuild. Choose the child item that matches your engine application.
