What does the +0.75mm sizing mean for these bearings?

The +0.75mm sizing indicates that these bearings are designed for use when the engine's crankshaft journals have been machined undersize by 0.75mm (approximately 0.030 inches) from their original factory diameter. This ensures proper oil clearance after crankshaft resurfacing.

What is the bimetal construction with an aluminum base?

A bimetal bearing typically has a steel backing for strength and a bearing material layer on top. In this case, the bearing material is aluminum-based, which offers good conformability and wear characteristics for supporting the rotating crankshaft.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required to service the main journals of the specified Nissan engines.

About this part

Product Details

Built with a bimetal construction using an aluminum base, this main bearing set from King Engine Bearings is specifically sized at +0.75mm for Nissan Ga14DE, Ga16DE, and Qg18DE engines. These bearings are a critical component in your engine's rotating assembly, supporting the crankshaft and ensuring it spins smoothly within the engine block. When rebuilding or repairing an engine, especially if the crankshaft has been machined undersize, using the correct size bearings is essential for proper oil clearance and long-term engine health.

King Engine Bearings is a well-known name in engine components, and this set reflects their focus on reliable parts for various applications. The bimetal design offers a good balance of strength and conformability, allowing the bearing to adapt slightly to the crankshaft surface for optimal contact and lubrication. This +0.75mm sizing means these bearings are intended for use when the crankshaft journals have been ground down by 0.030 inches (0.75mm) from their original size.

For a successful engine rebuild, ensuring your crankshaft journals are clean and properly measured is key before installing these bearings. Always refer to your vehicle's specific service manual for detailed installation procedures and torque specifications.
