In automobile and tractor engines, the camshafts (or cam lobes) are made of chilled cast iron, which is comparable to the alloyed steels used in the manufacture of bearings. The wear resistance of chilled cast iron is considerably higher of that of ductile cast iron.

Why are camshafts made of cast iron?
Generally, the camshaft is made from Chilled iron castings, because this material has far superior wear characteristics than any other material. Hardenable iron (developed in 1930)- low cost replacement for steel. Spheroidal graphite cast iron (used by FIAT in 1980s) - failed due to its low hardness value in cast form.
What are the basic parts of a camshaft?
Three main parts make up a camshaft: the main journals, the lobes and the ends. Cam bearings are another important part of a camshaft. A valuable part of the engine, a camshaft helps the engine rotate.
What is crankshaft material?
Crankshafts are made from forged steel or cast iron. Crankshafts for high-volume, low-load production vehicles are generally constructed from nodular cast iron, which has high strength (see Appendix D). Fuel-efficient engines require a high power-to-displacement ratio, which has increased the use of forged crankshafts.
What kind of steel are S cams made of?
The existing material of the S-camshaft is mild steel (MS) and the Torque plate is spheroidized Cast Iron (CI). Evaluate and select the higher strengthen material than cast iron and mild steel.
What is a camshaft core?
Cam cores, or an unground lobe camshaft (UGL), are essentially unfinished camshafts, as you'll see in the video. These are cams waiting to be machined and ground to precision for various applications. The four different camshaft core types are: Cast Iron Core. Austempered Iron Core.
How are camshafts forged?
Conventionally, the hot forging method was used in the manufacture of camshafts, which comprises melting a material by heating, compressing the melted material in a die to form a roughly formed piece, cutting the roughly formed piece, quenching and tempering the cut piece and subjecting the thermally treated piece to a ...
Are camshafts cast or forged?
Camshafts in automobiles are made from steel or cast iron, and are a key factor in determining the RPM range of an engine's power band.
Who invented camshaft?
Camshaft - Invented by Al-Jazari
The cam and camshaft were invented by Al-Jazari in 1206 and were part of his 'castle clock' - a complex water-powered astronomical clock.
How many types of camshafts are there?
There are four different types of camshafts (hydraulic flat tappet pictured), and each one operates in conjunction with a specific tappet or lifter or follower.
What is cam in mechanical engineering?
A cam is a rotating or sliding piece in a mechanical linkage used especially in transforming rotary motion into linear motion. It is often a part of a rotating wheel (e.g. an eccentric wheel) or shaft (e.g. a cylinder with an irregular shape) that strikes a lever at one or more points on its circular path.
What is journal in camshaft?
n a type of camshaft situated above the cylinder head in an internal-combustion engine. It is usually driven by a chain or a toothed belt from the crankshaft and the cams bear directly onto the valve stems or rocker arms. blog n. Online journal where the writer presents a record of activities, thoughts, or beliefs.
What is cam bearing?
What Are Cam Bearings? A vehicle's camshaft works in close synchronicity with the crankshaft to provide power to drive the vehicle. ... To host the camshaft and allow rotation, cam bearings are installed into “bearing bores” and specifically designed so that they are adequately lubricated during operation.
