Overview

Short Description: Shaft forgings (mechanical components) Shaft forgings are cylindrical objects that are worn in the middle of the bearing or in the middle of the wheel or in the middle of the gear, but a few are square. A shaft is a mechanical part that supports a rotating part and rotates therewith to transmit motion, torque or bending moments. Generally, it is a metal rod shape, and each segment can have a different diameter.
