What does 'STD' size mean for these bearings?

STD stands for standard size. This means the bearings are manufactured to the original equipment manufacturer's specifications and are intended for use when the crankshaft journals are in good condition and have not been machined undersize.

What is the benefit of bi-metal aluminum construction?

Bi-metal aluminum construction offers a good balance of strength and conformability. The aluminum provides a good bearing surface, while the bi-metal design helps manage heat and wear effectively, especially in medium-load applications.

Are these bearings environmentally safe?

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