What does '+0.50mm' mean for these bearings?

The '+0.50mm' designation indicates that these bearings are 0.50mm undersize. This means they are intended for use when the engine's crankshaft has been machined down by 0.50mm as part of an engine rebuild or repair process.

What is a bimetal aluminum base construction?

A bimetal aluminum base construction uses a layer of aluminum alloy bonded to a steel backing. This design offers good wear resistance and thermal conductivity, making it a solid choice for engine bearings that handle significant load and heat.

Do I need to replace my crankshaft when using these bearings?

Yes, if your crankshaft journals have been machined down by 0.50mm, you will need to use these +0.50mm undersize bearings. If your crankshaft is still at standard size, you would need a standard size bearing set instead.
