Description
This is a set of Connecting Rod Bearing Set in Standard size made with the Bi-Metal material for MGB 1965 to 1980 five main engine. There are many adavantages of using the Bi-Metal bearing in street applications. You can be assured we at British Parts Northwest can supply the correct engine bearings to fit your needs and application. Cross Ref.# 425-760, 4B2550STD, B4512LCSTD, CR4403AMSTD
- High Anti-Seizure Capibilities Particularly with cast iron crankshafts. This is provided by silicon particles in the bearing which continuously polish the crankshaft surface and prevent seizure.
- Conformability Capiblities Ability to adapt to assembly and misalignment In contrast to Tri-metal bearings with thin overlays, Bi- metal materials are capable of accommodating greater misalignments enables the alloy to conform without compromising strength.
- Compatibility Ability to accommodate shaft to bearing contact through thin oil films Silicon particles at the bearing surface polishing agent continuously polish the crankshaft surface crankshaft roughness and adapts to maintain oil film integrity.
- Short Term Oil Failure Ability to continue operation during temporary oil film breakdown The tin in the alloy of the bearing provides lubricity and low melting point liquid lubricant to keep the engine.
- Anti Wear Resistance to abrasion by crankshaft and debris Reduced wear is achieved by the relatively harder surface of the Aluminum alloy, which is harder than the soft overlay of Tr-Metal bearings.
- Embeddability The ability to absorb dirt entrained in the oil without damage to the bearing or shaft The lining of the bearing is thick so it is capable to absorb both small and large particles Since the aluminum alloy is significantly softer than crankshaft material, hard particles will be readily embeded rather than score the shaft.
- Good Conformibitliy The ability to accomodate misalignments In contrast to Tri-Metal beaings with thin overlays, bi-metal bearings materials are capable of accomodating greater misalignments.
- Anti-Corrosion Ability to withstand chemical attack from degraded or contaminated oil. The Aluminum alloy is virtually impervious to contaminants related to degraded or contaminated lubricating oil which can be caustic
