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 0.50mm. This is typically done during an engine rebuild to remove wear or imperfections from the original journals.

What is a bimetal bearing construction?

A bimetal bearing uses two different materials layered together. In this case, it has an aluminum base, which helps with heat dissipation and wear resistance, crucial for smooth engine operation.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required for your Toyota 12R engine's bottom end rebuild.
