Clevite 1, Tri-Metal Connecting Rod Bearing is a steel backed copper-lead matrix with overlay.
Clevite Connecting Rod Bearing part number CB1657AL25MM (0.25mm / 0.010in. Oversize)
Clevite Tri-Metal 1,Connecting Rod Bearings combine the strength of a copper-lead matrix (Bi-Metal) layer with steel backing and an electro-plated Micro Babbitt metal as an overlay.
The steel backing on the Clevite Tri-Metal 1,Connecting Rod Bearings provides strength and durability. The copper-lead matrix overlay provides the conformability and Load Capacity. The Third layer - Micro-Babbitt overlay provides the critical surface Embedability & Conformability and has far more forgiveness than bi-metal.
This ideal design has properties not found in many original equipment bearings. In most cases Clevite Tri-Metal 1 Bearings are an upgrade over a stock bearing, or three times better.
It takes Three Layers to be Number One, and Clevite 1 Tri-Metal Bearings are it !
Engineering quality engine bearings involves a number of interdependent factors. Here is how Clevite 1’s Tri-Metal cast copper-lead matrix compares to bi-metal bearings on the most important of these factors:
Tri-Metal bearings have significantly greater seizure resistance than bi-metal bearings.
Tri-Metal bearings can withstand much higher loads for longer periods of time as compared to bi-metal bearings.
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 1’s Tri-Metal bearings exceed light vehicle OE durability requirements of 150,000 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 1, Tri-Metal Engine Bearings.
