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

The +0.25mm sizing means these bearings are intended for use on a crankshaft that has had its main journals machined down by 0.25mm. This is a common step during engine rebuilding to correct wear or imperfections on the original journals.

What is the advantage of King's tri-metal material?

King Engine Bearings uses a tri-metal material that is known for its strength and resistance to wear. This construction helps ensure the bearings can withstand the stresses of engine operation and maintain proper function over time.

Are these bearings a direct replacement for stock Nissan TB48DE bearings?

These bearings are designed for the Nissan TB48DE engine but are specifically sized at +0.25mm. If your crankshaft journals are still at their original factory size, you would need a standard size bearing set, not this +0.25mm set.

Product Details

These King Engine Bearings main bearings are built with a high-performance tri-metal material, specifically designed for the demands of the Nissan TB48DE engine. The +0.25mm sizing indicates these bearings are intended for engines that have been machined to a larger diameter on the crankshaft journals, a common practice during a rebuild to correct wear or out-of-round conditions.

King uses a unique overlay material that's tougher and more resistant to wear than standard bearings, which helps extend the life of your engine's rotating assembly. This particular set is engineered to handle the stresses of the TB48DE, offering a solid option for rebuilding or repairing this engine. The precise sizing ensures a proper fit on the crankshaft, which is critical for maintaining oil clearance and ensuring adequate lubrication.

When rebuilding an engine, using bearings that match the machined size of your crankshaft is essential for proper oil pressure and bearing longevity. These King bearings are a well-built choice for your Nissan TB48DE project.
