Crank Shaft

Super Finish Ease of Use No Setup Time

A crankshaft translates the linear reciprocating
motion of the piston into the rotational motion.
This is accomplished by connecting the pistons to
the crank throws, which are then offset from the
central axis of the crankshaft to create a rotation
of that axis.
Crankshafts can be monolithic (made in a
single piece) or assembled from several pieces.
Monolithic crankshafts are most common, but
some smaller and larger engines use assembled
crankshafts. Crankshafts can be forged from a
steel bar usually through roll forging or cast in
ductile steel. Today, more and more manufacturers
tend to favor the use of forged crankshafts
due to their lighter weight. Crankshafts can
also be machined out of a billet, often a bar of
high quality vacuum remelted steel. Machining
or remanufacturing crankshafts are precision
machined to exact tolerances without odd size
crankshaft bearings or journals. ISCAR has
developed long solid carbide drills for crankshaft
oiling holes. For bearings or journal cranks,
ISCAR’s milling, turning and tooling solutions
assure high productivity.
