What does the 0.25mm size mean for these bearings?

The 0.25mm designation indicates that these bearings are undersize. This means they are intended for use when the crankshaft journals have been machined down by 0.25mm to account for wear or to achieve a specific clearance. Always verify your crankshaft specifications before ordering.

What is the advantage of the lead-free composite material?

The lead-free composite material is an environmentally safer option compared to traditional bearing materials. It's also specifically chosen for its suitability in medium-load engines, providing reliable performance and durability for applications like diesel trucks.

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

These bearings are described as ideal for medium-load engines. While well-built for their intended application, King Engine Bearings offers other specialized series for higher-performance or racing needs if your project demands extreme loads.
