SHAFT ONLY - MP30V

A shaft is a rotating machine element, 
usually circular in cross section, 
which is used to transmit power from one part to another,
 or from a machine which
 produces power to a machine which absorbs power.

The drive shaft (also called propeller shaft or prop shaft
) is a component of the drive train in a vehicle,
 with the purpose of delivering torque from
 the transmission to the differential, 
which then transmits this torque to the wheels in order to move the vehicle.

The shaft in a motor is a cylindrical component that
 extrudes out from the motor and its housing. 
The purpose of the shaft is to convert energy from
 the motor into the end use application.
 Precision pins and shafts 
operate as a function of speed vs torque.
