The Clevite 77 Engine Bearings have set the standard in the precision bearing industry since 1929, and Clevite offers the most extensive line of performance engine bearings on the market. Built to exceed even the highest OEM standards for strength and durability. Offshore racing has proven Clevite's superior engine bearings technology. H-Series Bearings, originally developed for use in racing, are ideal for all types of high-performance competition engines. H-Series bearings have a medium level of eccentricity, and high crush - the rod bearings feature a hardened steel back with thin overlay. H-Series rod and main bearings have an enlarged chamfer to clear the larger radii fillet common in marine racing crankshafts and are made without flash plating for better seating. The main bearings are available with standard 180 degrees upper half grooving. TCM recommends using H-Series bearings on crankshafts with oversized journal fillets, and medium to high RPM range engines. Part number CLE 1282P and CLE 1281P are good choices for crankshafts with standard radio fillet. Series Main Bearings are best suited for hardened racing crankshafts.
