H Series -

• Best to start with when unsure which bearing to choose
• Medium level of eccentricity and high crush
• Enlarged chamfers for greater crankshaft fillet clearance
• Made without flash plating for better seating
• Use with crankshafts that have oversized fillets
• Use with engines that run mid-high RPM range
• Contact patterns should ideally cover 2/3 to 3/4 of the bearing surface

   

  P Series -
• Typically the greatest level of eccentricity
• Rods and mains have high crush for maximum retention
• Most are fully grooved to maximize oil flow to rod bearings
• Reduced overlay thickness to prevent overlay fatigue
• Use where extremely high RPMs cause severe rod bore close-in
• Use where higher eccentricity is desired to narrow bearing contact patterns
