heres the info
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
V Series
This series essentially duplicates Clevite's former Vandervell parts
Typically low to medium eccentricity
Not available with oversized chamfers
No flash plating on the steel back
All main sets use a single-piece thrust bearing
Narrowed parts available to accommodate increased crankshaft fillet clearance
Lead-indium overlay offers slightly better conformability
