What does the +0.25mm sizing mean for these bearings?

The +0.25mm sizing indicates that these bearings are slightly larger than standard size. This is used when the crankshaft journals have been machined down by 0.25mm during an engine rebuild to remove wear or damage. It's crucial to match the bearing size to the machined crankshaft size.

What is PMaxBlack material?

PMaxBlack is a tri-metal copper-based material developed by King Engine Bearings. It's designed to offer superior load-carrying capacity compared to standard bearing materials, making it suitable for performance applications or engines that experience higher stress.

Do these bearings come with installation instructions?

While these bearings are a direct fit for the specified applications, it is always recommended to refer to the vehicle manufacturer's service manual or King Engine Bearings' official installation guidelines for proper procedure and torque specifications.

About this part

Product Details

This is a performance main bearing set from King Engine Bearings, specifically sized at +0.25mm for Nissan SR20DE and SR20DET 2.0L engines. These bearings are crucial for the health of your engine's crankshaft, providing a smooth, low-friction surface for it to rotate within the engine block. If you're rebuilding or refreshing your SR20, especially for performance applications, getting the right bearings is a key step.

King Engine Bearings specializes in this exact component, and this set uses their PMaxBlack tri-metal copper-based material. This construction is known for handling higher loads, which is important if your engine sees more demanding use. The Radialock feature helps ensure the bearings have the optimal crush height, meaning they seat properly in the block for consistent oil pressure and performance. This set is precisely sized at +0.25mm, which is important if your crankshaft has been machined to this size during a rebuild.
