Clevite H-Series performance bearings have a medium level of eccentricity, high crush, and a hardened steel back and thin overlay. These bearings are made without flash plating for better seating. Use H-Series bearings with crankshafts that have oversize fillets and where engines run in the medium to high RPM range. Manufactured from cast copper-lead, increases fatigue strength by approximately 20% compared to powdered metal processes, referred to as sintering, which is used by the competition H-Series bearings are narrowed for greater crankshaft fillet clearance All H-Series bearings are made in Atlantic, Iowa USA High crush for better seating and retention Un-plated hardened steel backing for better dimensional accuracy and bore contact UPC 027067544964 Brand Name Clevite 77 Unit Count 1.0 Count Item Weight 0.53 Kilograms Bearing Type Plain Bearing Manufacturer Clevite Material Type Alloy Steel, Metal Bearing Number MS 909H 1 Item Type Name Crankshaft Bearing Item Dimensions 5.51 x 3.54 x 3.54 inches Included Components Crankshaft Bearing Compatible Lubricant Oil Global Trade Identification Number 00027067544964
