Duraglide Performance Engine Bearings

Duraglide bearings are ACL’s original trimetal bearings (Copper, Lead, Tin) and are made in Australia. They are slightly different than Race Series bearings (metallurgical formulation) and have all the advantages associated with trimetal metallurgy. Duraglide bearings are made specifically for GM, Ford and Chrysler V-8 engines, including hemi engines.

 

Construction
1. TIN OVERPLATE

The overplate is 100% tin and thicknesses are nominally .007’.

2. NICKEL DAM

A lead-tin-copper overplate is applied to copper lead bearings. It is necessary however, to include a nickel intermediate layer (barrier plate or dam) to prevent tin migration from the overplate, which is a natural metallurgical phenomenon. Superior quality construction and control in electroplating eliminate potential overplate flaking.

3. COPPER LEAD INTERMEDIATE LAYER

Sintered copper lead alloys are of a similar chemical composition and generally withstand the same high compressive loads as cast alloy materials.

4. STEEL BACK

Utilizing mild-steel strip onto which is added powdered copper lead metal alloy. The strip is heated and compressed to bond the alloy to the steel backing.
