What does '0.25mm Oversized' mean for these bearings?

This means the bearings are manufactured to be 0.25mm larger in diameter than the standard size. They are intended for use when the crankshaft journals have been machined undersize by 0.25mm to clean up wear or damage. This ensures the correct oil clearance is maintained.

What is the advantage of aluminum alloy bearings?

Aluminum alloy bearings are popular for performance engines because they conform well to the crankshaft's surface. They also offer good heat dissipation, which helps prevent bearing damage under load.

Are these bearings sold individually or as a set?

This is a main bearing set, meaning it includes all the necessary main bearings required for a complete engine rebuild for your specified Nissan NX model.

Product Details

Doing an engine rebuild on your 1991-1993 Nissan NX with an SR20DE or SR20DET engine? This ACL main bearing set is a crucial component for ensuring your crankshaft spins smoothly and stays properly aligned within the engine block. These bearings are designed to be 0.25mm oversized, which is important if your crankshaft journals have been machined undersize during a rebuild to clean up wear or damage.

ACL is a well-known name in engine bearings, and this set is made from aluminum alloy. Aluminum bearings are a popular choice for performance applications because they offer good conformability to the crankshaft and have a good balance of strength and thermal conductivity. The 0.25mm undersize means these are intended for use when the crankshaft has been ground down by that amount to remove imperfections. It's important to match the bearing size to the crankshaft journal size for proper oil clearance and engine longevity.
