What does the +.25mm size mean for these bearings?

The +.25mm designation means these bearings are slightly larger than standard size. They are intended for use when the crankshaft journals have been machined down by 0.25mm to remove wear or imperfections. This ensures a proper fit and oil clearance after machining.

What is the Manganx material?

Manganx is a strengthened aluminum alloy used in the bearing construction. It's designed to enhance the bearing's ability to withstand the high loads and stresses encountered during engine operation, contributing to its overall durability.

Are these bearings safe for the environment?

Yes, these bearings are made with a lead-free composite material. This makes them an environmentally safer alternative compared to older bearing designs that contained lead.
