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

The +0.25mm sizing indicates that these bearings are intended for use when the main journals on your engine's crankshaft have been machined down by 0.25mm. This is a common practice during engine rebuilds to clean up worn or damaged journal surfaces.

What is the main function of main bearings in an engine?

Main bearings are a critical component of an engine's bottom end. They are located between the crankshaft and the engine block, providing a low-friction surface that supports the rotating crankshaft and maintains proper oil clearance.

What is the material of these King Engine Bearings?

These main bearings are made from a bimetal construction, featuring an aluminum silicon base. This material is chosen for its ability to handle heat and wear effectively within the engine.

Product Details

If you're rebuilding the bottom end of your Suzuki M15A, M16A, or M18A engine, a fresh set of main bearings is crucial. These bearings sit between the crankshaft and the engine block, supporting the rotating assembly and ensuring smooth operation. This set from King Engine Bearings is specifically sized at +0.25mm, meaning it's designed for crankshafts that have been machined to this size during an engine rebuild.

King uses a bimetal construction with an aluminum silicon base for these bearings. This material choice helps manage heat and wear effectively, which is important for the longevity of your engine. Because they are a +0.25mm size, they are intended for use when the main journals on your crankshaft have been ground down by 0.25mm to remove any imperfections or damage from previous use.

When you're rebuilding an engine, using bearings that match the machined size of your crankshaft is critical for proper oil clearance and performance. This set is a solid option for getting your Suzuki engine back in top shape.
