Overview

Clevite F-Series Main Bearings

Clevite F-Series main bearings are premium, high performance engine bearings engineered for high-output and racing applications. They serve as a premium evolution of traditional Clevite H-Series bearings by offering enhanced durability, load capacity, and seizure resistance.

Key features and construction:

* Tri-Metal Design: F-Series bearings use a specialized electroplated overlay consisting of lead, tin, indium, and alumina flakes applied over a cast bronze-lead substrate and a precision steel back
* Increased Seizure Resistance: The specific material composition of the overlay provides up to a 90 percent increase in seizure resistance compared to conventional copper-tin-lead overlays, protecting the crankshaft if oil pressure drops
* Massive Load Capacity: Testing shows a 126 percent increase in load-carrying capacity before seizure, capable of withstanding maximum loads of up to 12,000 psi
* Ramp and Pad Thrust Face: On applicable main bearings, this design increases oil pressure to the thrust wear surface. This boosts thrust load capacity by up to 93 percent compared to conventional flat pad designs
* Common Applications: F-Series main and rod bearings are specifically designed to withstand the rigors of performance V8 engines. They are widely used in:
-- Popular Chevrolet performance platforms (such as small block Chevy, big block Chevy, and LS engines)
-- Heavy-duty truck applications
-- Professional racing and high performance street builds
