The camshaft is a crucial component in a combustion engine. Its strategically aligned lobes, also called “Cams, ” are directly responsible for controlling the movement of the intake and exhaust valves.
Camshafts are directly responsible for the smooth working of the engines, or you can say that they are responsible for the system’s breathing. Cams move the valves up and down.
Camshafts work this way when the valves open to let the air into the engine system. It gives the hydraulic pressure on the valves, and when the closure of the system is needed, it releases the pressure, and the valves move backward, stopping the movement of the air coming into the system.
Camshafts are usually primarily used in automotive engines. Still, they are also used in many other industries’ engines and are crucial for their work in the aerospace, marine, and defense industries.
At Proleantech, we also work with several small businesses, from the automotive to the aerospace industry. They need high-performance camshafts made with state-of-the-art CNC machinery, whether they need prototypes or other parts like camshafts.

Diagram of a camshaft
1: Cam
The camshaft’s central and most important part is responsible for opening & closing the valve.
2: Cam Follower
This is the component that follows the cam movement. As the cam rotates, the cam follower is also pushed to operate the valves. In short, it is responsible for translating the cam’s action into valve movement.
3: Shaft
While the combustion engine is on the shaft, it is responsible for bearing stressful loads while the combustion engine is running and for supporting camshaft components by binding other parts.
4: Drive Shaft
The drive shaft connects the camshaft with the crankshaft by transferring power through a timing belt or chain. By this, the working of the crankshaft with the camshaft becomes possible by maintaining symmetry.
5: Lobes
Lobes are just like pear-shaped discs attached to camshafts that are responsible for pressing the valves, which ultimately gives them reciprocating motion to help them open and close for the engine.
6: Bearings
Bearings are responsible for keeping the shafts in their proper place and also helping the shaft reduce friction. Bearings also have a unique way of replacing the oil within a camshaft.
7: Chain Sprocket
It has a connection with the camshaft on one side and with the timing belt and sprocket on the other end, and it is responsible for keeping the synchronization of timing between the camshaft and crankshaft.
8: Thrust Plate
It is located in Between the timing gear & cam, minted on the front cover.

Flat-Tappet Camshafts
The flat tappet camshafts are those camshaft types with a flat base that rides on the cam/lobe and rotates around the lifter bore, which ensures the proper oiling and helps reduce the wear factor.
This is one the most common camshafts and has a flat surface on which the tappets or lifters are actually. These types of camshafts also need regular maintenance, which might include replacing the lifters or camshaft due to the wear factor.
You can use these camshafts in engines that need less performance, like old motorcycles, old trucks, classic cars, and many other engines.
4: Conjugate Camshafts
Conjugate Camshafts
This type of camshaft helps reduce the noise of the machining process in the industry. They have arrangements like two rollers connected with the cam follower or drive together that ultimately restrict the motion of the other parts.
These types of camshafts are less common than other types. You can use camshafts for the operation that needs more precision with the assurance of voice reduction.
5: Cylindrical Camshafts
Cylindrical Camshafts
Cylindrical camshafts are significantly less common in modern industries, also known as drum or barrel shafts, and grooves on their surface to guide cam followers’ motion.
Cylindrical Camshafts are often found in the portion of the industry that needs specialized machinery for unique & specific purposes with the fulfillment of precision and continuous motion control.
6: Overhead Camshafts (OHC)
Overhead Camshafts (OHC)
Overhead Camshafts (OHC) are one of the common types of camshafts that provide higher performance by the working system in which the camshaft is positioned directly above the valves, and this factor eliminates the need for pushrods.
