New Engine Bearing About 03 - 07 DODGE 3.7L SOHC OE Quality 7386MA Product Component: Engine Bearing 8 PCS Car Application: DODGE 3.7 SOHC 03/07, LI 2010-2002 DT L/D V6 3704cc 3.7L 2010-2002 JEE L/D V6 3704cc 3.7L What is an engine bearing In a piston engine, the main bearings are the bearings on which the crankshaft rotates, usually plain or journal bearings. The bearings hold the crankshaft in place and prevent the forces created by the piston and transmitted to the crankshaft by the connecting rods from dislodging the crankshaft, instead forcing the crank to convert the reciprocating movement into rotation. While some small single-cylinder engines have only one main bearing, designed to deal with the bending moment exerted by the crank as a result of the force from the connecting rod, most engines have at least two main bearings, one at each end of the crank shaft and may have as many as one more than the number of crank pins. Increasing the number of bearings in an engine will generally increase the size and cost of the engine, but also provides stability to the crankshaft, which would otherwise have to endure greater bending moments from having the crank pin further from a bearing. The combination of bearing number and crankshaft design can also have an effect on engine balance; a more stable crankshaft will better avoid unbalance from flexing, but increasing the crankshaft length or girth to accommodate an additional bearing increases the rotational inertia of the crankshaft, which can have the opposite effect. Our Advantage Maojia Industry is a leader of engine bearing in domestic, because of applying the new technology and solution to technology difficulites and keep OE quality. Our products improve the disadvantage of all the main bearing,making them longer use life. We already supply more than 1000 kinds of internal combusion engine bearings to the global aftermarket. At present, our company is the only one factory in China producing thrust bearing who can reach the OE quality. The successful research and develop of the product fills in the blank of edge bearing technology, and open a new situation for edge bearing.
