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

The +0.75mm sizing indicates that these bearings are designed to be used with a crankshaft that has been machined down by 0.75mm. This is a common practice during engine rebuilding to ensure proper oil clearance when the crankshaft journals are worn or resurfaced.

What type of engine load are these bearings best suited for?

These bearings feature a lead-free composite surface and are ideal for medium-load engines. This means they are well-suited for typical daily driving and moderate use, rather than extreme high-performance or racing applications.

Are these bearings environmentally friendly?

Yes, these bearings utilize a lead-free composite material. This makes them an environmentally safer option compared to older bearing designs that contained lead.
