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.
