King Engine Bearings CR4442AM0.5 Connecting Rod Bearing Set Datsun - A12

The King Engine Bearings CR4442AM0.5 is a connecting rod bearing set engineered for the Datsun A12 engine. This set is supplied in a 0.5mm undersize specification, designed for use during engine rebuilds where crankshaft journals have been machined or reground to restore proper clearances and surface geometry.

King Engine Bearings manufactures its connecting rod bearings using a multi-layer construction that delivers excellent load-bearing capacity, conformability, and resistance to fatigue. The "AM" series designates King's aluminum-tin alloy overlay, which provides superior corrosion resistance and embeddability compared to standard bimetal designs — helping the bearing conform to minor surface irregularities and embed small particles that might otherwise cause scoring.

Key Features:

• Designed for the Datsun A12 four-cylinder engine
• 0.5mm undersize — intended for reground crankshaft journals
• Multi-layer aluminum-tin (AlSn) alloy construction for durability and embeddability
• High fatigue strength for reliable performance under demanding conditions
• Precision manufactured to tight tolerances for consistent oil film clearance
• Corrosion-resistant overlay extends bearing service life
• Full set included for complete connecting rod journal service

These bearings are an ideal choice for engine rebuilders and performance enthusiasts restoring or rebuilding Datsun A12-powered vehicles. King Engine Bearings is a globally recognized OEM and aftermarket supplier trusted by professional engine builders worldwide.
