What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are designed for use when the engine's crankshaft journals have been machined down by 0.25mm. This is a common practice during engine rebuilds to ensure proper clearances with worn or reconditioned journals.

What is the construction of these King Engine Bearings?

These bearings feature a tri-metal construction. This typically includes a steel backing for strength, a middle layer for crush resistance, and a bearing surface overlay designed to reduce friction and wear.

Are these bearings suitable for a standard engine rebuild?

Yes, King Engine Bearings are a well-known brand for engine rebuilding. This specific set is designed for the connecting rod journals and requires the crankshaft to be machined to the +0.25mm undersize.

About this part

Product Details

These King Engine Bearings are built with a tri-metal construction, featuring a steel-backed overlay that's designed to handle the stresses of your engine. The specific overlay material used in this set is chosen for its ability to reduce friction and wear, which is crucial for the high-performance demands of BMW N47 C16/D16 engines. They are precisely sized at +0.25mm, meaning they are intended for use when the crankshaft journals have been machined to this specific undersize during an engine rebuild.

When you're rebuilding the bottom end of your BMW N47 C16/D16, getting the bearing clearances just right is critical for oil pressure and engine longevity. King Engine Bearings are a popular choice because they offer a well-built product that meets the needs of engine builders. This set is specifically for the connecting rod journals, ensuring proper lubrication and support for those high-stress components.

If you're in the process of rebuilding your engine, these bearings are a solid option. Make sure to confirm your crankshaft has been machined to the +0.25mm undersize before ordering, as these bearings will not fit standard size journals.
