What does '0.5mm undersize' mean for these bearings?

This means the bearings are 0.5mm smaller in diameter than a standard bearing. This size is typically used when the crankshaft journals have been machined undersize during a rebuild to correct wear or damage.

What is the 'pmax black' racing line?

The 'pmax black' designation refers to King's performance racing line of bearings. This design is intended to handle higher loads and RPMs compared to standard bearings, offering improved durability in demanding engine applications.

What is tri-metal construction?

Tri-metal bearings use three distinct layers of material. This construction provides a strong, wear-resistant surface that also allows for good embeddability of dirt particles and maintains oil film strength under high stress.

About this part

Product Details

Built with a tri-metal construction, these performance rod bearings are a solid option for your Nissan TB42, TB45, or TB48 L6 engine. The 'pmax black' racing line indicates a design focused on handling higher loads and RPMs, making them suitable for performance applications where stock bearings might fall short. This set is specifically sized at 0.5mm, meaning they are 0.5mm undersize from standard, which is often used when the crankshaft journals have been ground down during a rebuild.

King Engine Bearings uses a multi-layer material system that balances strength, wear resistance, and embeddability. This combination helps to maintain oil pressure and protect the crankshaft journals under demanding conditions. If you're rebuilding the bottom end of your Nissan L6 engine and looking for a well-built bearing that can handle more than stock power, this set is worth considering.
