What does the '+0.5' size mean for these bearings?

The '+0.5' designation indicates that these bearings are 0.5mm (approximately 0.020 inches) larger in diameter than standard size. This means they are intended for use on a crankshaft that has been machined down by that amount to correct for wear or damage.

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

These bearings are specifically noted as being ideal for medium-load engines. Their bi-metal aluminum construction with a lead-free composite is designed for reliable performance in applications that are not subjected to the highest levels of stress.

Are these bearings environmentally safe?

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