What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are slightly larger than standard size. This is typically used when the crankshaft journals have been machined down by 0.050mm (or 0.020 inches) during an engine rebuild to ensure a proper bearing-to-journal clearance.

What is PMaxBlack technology?

PMaxBlack is a technology developed by King Engine Bearings that enhances the load capacity of the bearings. This means they are better equipped to handle the pressures and stresses within the engine, contributing to improved durability.

Are these bearings suitable for a performance build?

The PMaxBlack technology and tri-metal copper-based construction offer superior load capacity and durability, making them a solid option for engines that see demanding use. However, for extreme performance applications, it's always best to consult with an engine builder.
