MAHLE CLEVITE P-Series Standard Size Tri-Metal Main Bearing Set. This ideal design has properties not found in many original equipment bearings. In most cases Clevite Tri-Metal 112 Bearings are an upgrade over a stock bearing, or three times better! It takes Three Layers to be Number One, and Clevite 112 Tri-Metal Bearings are it!
Engineering quality engine bearings involves a number of interdependent factors. Here is how Clevite 1’s Tri-Metal cast intermediate layer of copper-lead alloy and an electro-plated lead-base overlay material compares to bi-metal bearings on the most important of these factors:
Tri-Metal bearings have significantly greater seizure resistance than bi-metal bearings, by as much as 35%.
Tri-Metal bearings can withstand much higher loads for longer periods of time as compared to bi-metal bearings, over 50% higher loads.
-Embeddability & Conformability:
The overlay on a Tri-Metal bearing offers a far more forgiving surface than bi-metal bearings. This feature may not be as critical during OE assembly as it once was, but it does offer additional protection that can be extremely beneficial in maintaining your engine.
Clevite 112’s Tri-Metal bearings not only exceed light vehicle OE durability requirements of 150,000 miles, they also exceed heavy vehicle OE durability requirements of 300,000 miles.
Because the surface layer of a Tri-Metal bearings adds an additional manufacturing step, Clevite regularly holds wall sizes to within .0005” as compared to a bi-metal that can be held to within .0003”.
*Not all Tri-metal engine bearings are the same - so if you want the strongest, highest quality engine bearings, ask for the original Clevite 112 Tri-Metal
