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

The +0.75mm sizing indicates that these bearings are designed for crankshaft journals that have been machined down by 0.75mm. This larger bearing size is needed to restore the correct oil clearance after journal resizing.

What is the advantage of a bi-metal aluminum material?

Bi-metal aluminum construction is common for engine bearings because it offers good strength and wear characteristics, making it a solid choice for medium-load engine applications.

Are these bearings environmentally friendly?

Yes, these main bearings feature a lead-free composite material, which is considered an environmentally safer option compared to traditional lead-based bearing materials.
