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

The '+0.50mm' indicates that these bearings are 0.50 millimeters larger in diameter than standard size bearings. This is typically used when the crankshaft journals have been machined down (ground) to remove wear or damage, or for a fresh rebuild with specific clearance targets.

What is 'trimetal' construction?

Trimetal bearings use a three-layer material construction. This design typically includes a steel backing for strength, a middle layer of copper-lead alloy for load capacity, and a thin overlay of babbitt (a soft alloy) for conformability and embeddability, offering good wear resistance.

Do I need to replace the crankshaft when using these +0.50mm bearings?

Yes, if your crankshaft journals have wear or damage, they will need to be machined down to a +0.50mm undersize to match these bearings. If your crankshaft is still within standard specifications, you would use standard size bearings instead.

About this part

Product Details

This set includes connecting rod bearings for your Honda F23A, F23Z, K20A3, or 16V engine. These bearings are sized +0.50mm, meaning they are slightly larger than stock to accommodate engine wear or a freshly machined crankshaft. They are built with a strengthened trimetal construction, which is a well-built material choice for handling the stresses inside your engine.

King Engine Bearings are a popular choice for many builds, from daily drivers to more performance-oriented applications. This particular set is designed to fit a range of vehicles, including models like the Acura CL, Honda Accord, and Honda Civic. The trimetal design offers good load-carrying capacity and wear resistance, which is crucial for the high-speed rotation and pressure experienced by connecting rod bearings.

When rebuilding or refreshing an engine, using bearings that are the correct size and made from durable materials is key to a long-lasting rebuild. This set provides a solid option for those looking to replace worn bearings or ensure proper clearances after engine work.
