What does the +0.25mm size indicate?

The +0.25mm size means these bearings are slightly larger than standard. They are used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild to ensure a proper fit and oil clearance.

What are the benefits of Manganx strengthened aluminum?

Manganx strengthening is a process that enhances the durability and performance of the aluminum material used in the bearing. This helps the bearing withstand the stresses of engine operation.

Are these bearings environmentally safe?

Yes, these bearings are made with a lead-free composite material, making them an environmentally safe option.
