Mahle/ Clevite Connecting Rod Bearing CB-663HN-1

Description

These bearings were developed primarily for use in NASCAR type racing, but are suitable for all types of competition engines. H series bearings have a medium level of eccentricity, high crush, and rod bearings have a hardened steel back and thin overlay. These bearings also have enlarged chamfers for greater crankshaft fillet clearance and are made without flash plating for better seating. Bearings with 0.001 Inch extra clearance are available for standard size shafts and carry the suffix HX` (X = extra clearance). Rod bearings are available with or without dowel holes (HD = with, H = without), main bearings are available with standard 180 Degree upper half grooving and with full 360 Degree grooving (H = 180 Degree, HG 360 Degree). Use H series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. H series bearings should be used if contact patterns obtained with P series parts are too narrow. Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface. If you aren`t sure which type of performance bearing to start with, the H series bearing will be your best choice.
