What does the +0.50mm sizing mean for these bearings?

The +0.50mm sizing indicates that these bearings are intended for use when the crankshaft journals have been machined down by 0.020 inches (0.50mm) during an engine rebuild. This ensures a proper fit and oil clearance on the resized journals.

What is the benefit of the tri-metal copper-based material and Babbitt overlay?

The tri-metal construction provides a strong foundation, while the copper-based material offers good thermal conductivity. The enhanced Babbitt overlay offers improved embeddability and conformability, which helps to protect the crankshaft journals and maintain proper oil film.

Are these bearings suitable for high-performance or racing applications?

These bearings are designed for medium-load engines. For high-performance or racing applications, it's always best to consult with an engine builder or refer to manufacturer specifications for the most demanding uses.
