What does the '+0.25mm' size indicate for these main bearings?

The '+0.25mm' designation means these bearings are 0.25mm thicker than standard. They are used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild to ensure proper clearance and support.

What is the purpose of main bearings in an engine?

Main bearings are situated between the crankshaft and the engine block. They provide a low-friction surface that supports the crankshaft as it rotates, handling the immense forces generated during combustion.

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 for a complete installation on the specified Nissan P/Pf 86Ci engine.
