Shafts are crucial components used in machinery. They support rotating elements such as pulleys and gears, supported by bearings within the rigid machine housing. Gears and pulleys mounted on the shafts contribute to the transmission of motion.

Many other rotating components are keyed onto shafts. They endure bending moments and torques due to reactions from supported components and power transmission.

Shafts always have circular cross-sections and can be either hollow or solid. They can be classified as crankshafts, straight shafts, articulated shafts, or flexible shafts, although straight shafts are typically used for power transmission.

Shafts are usually designed as steep cylindrical bars, hence they have varying diameters along their length, although shafts with constant diameters are easier to manufacture.

The magnitude of stress in stepped shafts varies with their length. Shafts with uniform diameters are unsuitable for disassembly, assembly, maintenance, and these shafts introduce complexity when securing components, especially bearings, to them.

Cast iron is one of the oldest ferrous metals used in construction and outdoor ornament. It is primarily composed of iron (Fe), carbon (C) and silicon (Si), but may also contain traces of sulphur (S), manganese (Mn) and phosphorus (P). It has a relatively high carbon content of 2% to 5%.
