Clevite CB1665HNDC H-Series Connecting Rod Bearing Narrowed Doweled Coated

The Clevite CB1665HNDC is a high-performance H-Series connecting rod bearing engineered for demanding racing and high-performance applications. This precision bearing features a narrowed design on one side for increased crankshaft fillet clearance, making it ideal for engines with oversize crankshaft fillets running in medium to high RPM ranges.

Key Features:

• H-Series performance design with medium eccentricity and high crush factor for maximum bearing retention
• TriMetal construction: hardened steel back, copper-lead alloy substrate, and thin electroplated overlay for superior strength and durability
• TriArmor coating: moly/graphite dry film treatment for enhanced protection, reduced friction, and increased seizure resistance
• Narrowed on one side for increased crankshaft fillet clearance
• Dowel hole in cap half—can be used in engines with or without doweled connecting rods
• Enlarged chamfers for greater crankshaft fillet clearance
• Made without flash plating for better seating and contact patterns
• TM-77 material construction for race-proven reliability

Specifications:

• Shaft diameter: 1.8885" - 1.8890" (47.968mm - 47.981mm)
• Housing bore: 2.015" (51.181mm - 51.194mm)
• Bearing length: 0.851" (21.615mm)
• Oil clearance range: 0.001" - 0.003" (0.025mm - 0.066mm)
• Maximum wall thickness: 0.0625" (1.587mm)

Clevite H-Series bearings have been the choice of professional engine builders since 1948, with proven performance in NASCAR and professional racing applications. The combination of TriMetal construction and TriArmor coating technology delivers exceptional wear resistance and extended bearing life in both high-performance street engines and full-race applications.
