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

The '+0.50mm' indicates that these bearings are 0.50mm undersize. This means they are intended for use when the engine's crankshaft has been machined down by 0.50mm to correct wear or damage. Always confirm your crankshaft's journal size before ordering.

What is the advantage of the bi-metal aluminum material?

The bi-metal aluminum construction offers good load-carrying capacity for low to medium-load engines. It's also lead-free, making it an environmentally safer choice compared to older bearing materials.

Does this main bearing set come with all the necessary components for installation?

This listing is for the main bearing set only. It includes the main bearings themselves. You will typically need to purchase separate oil seals, gaskets, and potentially other engine components for a complete engine rebuild.

About this part

Product Details

If you're rebuilding the engine in your Toyota or Lexus, getting the crankshaft spinning true is critical, and that's where main bearings come in. This set from King Engine Bearings is specifically for the 1Mzfe engine and is sized 0.50mm undersize, meaning it's meant for crankshafts that have been machined down to match. King has been focused on making bearings since 1960, so they know their stuff when it comes to keeping your engine running smoothly.

These bearings use a bi-metal aluminum material that's lead-free and environmentally safe, making them a solid option for low to medium-load engines like those found in many daily drivers. The material is chosen to handle the pressures and friction of the rotating crankshaft, helping to ensure a long life for your rebuilt engine. They fit a wide range of popular Toyota and Lexus models, including the Camry, Avalon, and RX series vehicles.
