What does the +0.50mm size mean for these bearings?

The +0.50mm designation indicates that these bearings are slightly larger than standard size. This is necessary when the engine's crankshaft journals have been machined down by 0.50mm due to wear or damage. Using the correct oversize bearing restores the proper oil clearance.

What is the King XP high-performance overlay?

The XP overlay is a special multi-layer coating applied by King Engine Bearings. It's designed to reduce friction between the bearing and the crankshaft, and it also improves wear resistance, helping to extend the life of both components.

Do these bearings come with installation instructions?

While these bearings are designed for a direct fit into the specified Nissan TB48DE engine, it is always recommended to refer to the manufacturer's official service manual for detailed installation procedures, torque specifications, and proper oil clearance measurements.

About this part

Product Details

Starting with a +0.50mm oversize, these King Engine Bearings main bearings are built for Nissan TB48DE engines. When your engine's crankshaft journals have been worn beyond standard specifications, using an oversize bearing like this set is crucial for restoring proper oil clearance and ensuring the engine can be rebuilt correctly. King uses their XP high-performance overlay, which is a multi-layer coating designed to reduce friction and wear, especially important in high-stress engine applications.

This set is designed to fit right into your Nissan TB48DE, replacing the worn main bearings with a well-built component that helps protect your crankshaft. The XP overlay is a notable feature, offering improved durability and smoother operation compared to standard bearings. This means better oil retention and a more consistent film between the bearing and the crankshaft, which is key for engine longevity. If you're rebuilding the bottom end of your TB48DE and need to account for journal wear, this +0.50mm set is a solid option.
