MAHLE / CLEVITE : MS2199A Crankshaft Main Bearing
  • A Steel backed lead free aluminum silicon alloy bearings without overlay. Standard replacement material.: M Steel backed bearings with a Micro-Babbitt lining (a very thin layer of lining which reduces the microscopic deflections that occur to a bearing when loaded and thus increases fatigue life). Solely intended for extreme high-horsepower applications.
  • AL Solid cast aluminum alloy bearings (material designation AL-1) or steel backed bearings with an aluminum alloy lining material designation AL-3, AL-4, AL-5, AL-6). Standard replacement material.: N Narrowed for greater crankshaft fillet clearance.

  • C Steel backed bearings with a copper-lead lining.: R Indicates that the bearing can be resized to standard. When following a camshaft bearing, indicates that it has extra bore stock in the inside diameter.
  • D Bearing has dowel hole.: S Indicates a set number designation.
  • G Steel backed bearings with a matrix of copper and an infiltrant of lead-tin babbitt. Precision undersizes are not resizable.: V High performance bearing with a lead-indium overlay (on main sets this indicates partial groove). Solely intended for extreme high-horsepower applications.
  • H High performance bearing (on main sets this indicates partial groove). Perform the same as "A" and "P" bearings, but have the ability to carry more load.: VG High performance bearing with a lead-indium overlay and a full annular groove. Solely intended for extreme high-horsepower applications.

  • AL Solid cast aluminum alloy bearings (material designation AL-1) or steel backed bearings with an aluminum alloy lining material designation AL-3, AL-4, AL-5, AL-6). Standard replacement material.: N Narrowed for greater crankshaft fillet clearance.
  • B Steel backed bearings with a conventional babbit lining.: P Steel backed bearings with an intermediate layer of copper-lead alloy and an electroplated lead-tin-copper overlay. Standard replacement material.
  • C Steel backed bearings with a copper-lead lining.: R Indicates that the bearing can be resized to standard. When following a camshaft bearing, indicates that it has extra bore stock in the inside diameter.
  • D Bearing has dowel hole.: S Indicates a set number designation.
  • G Steel backed bearings with a matrix of copper and an infiltrant of lead-tin babbitt. Precision undersizes are not resizable.: V High performance bearing with a lead-indium overlay (on main sets this indicates partial groove). Solely intended for extreme high-horsepower applications.
  • H High performance bearing (on main sets this indicates partial groove). Perform the same as "A" and "P" bearings, but have the ability to carry more load.: VG High performance bearing with a lead-indium overlay and a full annular groove. Solely intended for extreme high-horsepower applications.
  • HG High performance full annular grooved bearing. Perform the same as "A" and "P" bearings, but have the ability to carry more load.: X Bearing has .001” more oil clearance than standard.
  • HT High performance with indentless locating lug. “Full Bore” design. Perform the same as "A" and "P" bearings, but have the ability to carry more load.: XX Bearing has .002” more oil clearance than standard.
  • K TriArmor™ coating applied to the bearing surface, which offers extraordinary protection and lubricity. Enhanced wear characteristics increase bearing life in race engines and high performance street Engines.: W Indicates a part that is a thrust washer (may also be designated upper or lower).
