Mahle Engine Connecting Rod Bearing Pair CB-745HN-10

The Mahle CB745HN10 is a connecting rod bearing from the H-Series line, developed for NASCAR-style racing and competition engines. These bearings feature hardened steel backs with thin overlays, a medium level of eccentricity, and a high crush factor. They are designed with enlarged chamfers for increased crankshaft fillet clearance and are manufactured without flash plating to ensure better seating. The H-Series bearings are recommended for engines operating in the medium to high RPM range, especially when used with crankshafts that have oversize fillets or when P-Series bearing contact patterns are too narrow.
