Classification and Types of Shafts:
In production, special categories of shaft manufacturing for conveyors, machine tools, presses, sawmills, and other equipment are highlighted. Spare parts for repair and assembly work are also custom-made.
The classification of shafts is quite complex. By material, shafts are distinguished as made of black steel, stainless steel, aluminum, and titanium. Shafts are also divided into different classes. Among the main differences, the division by purpose is considered.
The main grades are Steel 20, Steel 45, and Steel 40X with subsequent heat treatment.
