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.
