Description
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 Clevite main bearing sets use a single-piece thrust bearing
- Narrowed parts available to accommodate increased crankshaft fillet clearance
- Lead-indium overlay offers slightly better conformability
M Series - - These are special purpose bearings having a nominal .005" thick Babbitt lining on a hardened steel back
- They are intended mainly for Blown Fuel engines where severe crankshaft deflections cause edge loading of the bearings
- Under these operating conditions bearing service life will be very short
- Frequent inspection and replacement is recommended
