What does the 0.025 inch undersize mean for these bearings?

An undersize bearing, like this 0.025 inch set, is used when the engine's crankshaft has been machined down to correct for wear or damage. These bearings are thicker than standard size to account for the material removed from the crankshaft journals.

What is the construction of these Clevite main bearings?

These bearings utilize a tri-metal construction. This design combines different layers of materials to provide a strong yet conforming surface that works well with the crankshaft.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required to service the crankshaft for the specified engine application.

Product Details

This Clevite main bearing set features a 0.025 inch undersize, meaning it's designed for crankshafts that have been machined down to compensate for wear. These bearings are crucial for supporting the crankshaft within the engine block, maintaining the correct oil clearance for smooth operation and preventing metal-on-metal contact. They are built to handle the demands of engines like the Nissan KA24DE and KA24E, found in popular vehicles such as the Nissan 240SX, Altima, and Frontier.

Clevite uses a tri-metal construction for these bearings, which offers a good balance of strength and conformability. This design helps them adapt to minor imperfections in the crankshaft journal while still providing solid support. Proper installation is key; ensuring the crankshaft journals are clean and within the specified tolerance for this 0.025 inch undersize set is vital for long-term reliability. If you're rebuilding or repairing your engine, these bearings are a well-built choice for restoring proper crankshaft function.
