What is meant by cam follower?
: the peg or roller which follows the curvature of a cam and to which the motion of the cam is thereby directly communicated.
What is the purpose of a cam follower?
Cam follower bearings are also known as track followers. As the name implies, they are essential to make the cam followers work effectively. Cam followers are capable of handling intermittent shock and heavy loads. They also can have a soft core that allows for extreme shock loads without fracture.
Is a cam follower a lifter?
The cam follower is a cylindrical device that tracks the shape of the cam lobe and reciprocates the movement to the opening and closing of the valves in the combustion chamber. The follower drives a piston that is enclosed in a cylindrical casing. This casing-piston assembly is known as the lifter.
What is a follower in a cam and follower?
A follower is a mechanical component concerning which, the Cam rotates in an oscillatory or circular motion. Follower inhibits the push and pulls of the Cam. A follower is used to transfer the motion to the required machine part. The Follower rotates in an oscillating or circular arc.
How does cam follower works?
Cams are used to convert rotary to linear (reciprocating) motion. As the cam rotates, the follower rises and falls in a process known as reciprocating motion. The follower maintains contact with the cam through the force of gravity or by a spring. The total range of movement produced by the cam is called the stroke.
What are the types of cam & follower?
Types of cams and follower
- (A) According to type of shape (1) Radial or Disc cam (2) Cylinrical cam (3) Translation or Wedge cam (4) Conjugate cam (5) Globoidal cam (6) Spherical cam Types of cams…

How do I know if my cam follower is bad?
Fuel cuts and loss of boost are the main symptoms of a bad cam follower.
What are the types of cam follower?
What are the 5 types of followers?
Kelley developed a theory of followers describing five types: Conformist, Passive, Alienated, Exemplary and Pragmatic.
How are cam followers classified?
Cams can be classified based on their physical shape. 4.1a and b): The disk (or plate) cam has an irregular contour to impart a specific motion to the follower. The follower moves in a plane perpendicular to the axis of rotation of the camshaft and is held in contact with the cam by springs or gravity.
What are the four basic cam shapes names?
Cams come in a variety of shapes and sizes – the most common types (from left to right): snail shaped, pear shaped and a circular with an off-centre hole. As the cams rotate, the followers reciprocate motion according to the profile of each cam.
Which is an example of a cam follower?
A cam follower is a component that is intrinsically tied to a cam. Cams exist in many applications–dishwashers, sprinklers, etc.–but the most well-known example is that of a camshaft in a car. The goal of a cam is to convert rotary motion to linear motion.
What does a spiral cam and follower look like?
The spiral cam has a half-circular or a spiral shaping grooved contour, the cam moves in reciprocating motion and the follower moves vertically to the axis of the cam. This type of cam looks like an asymmetric heart. It is mainly used to return a shaft to hold the cam to a set position by its pressure from a roller.
What kind of follower does a disc cam have?
A disc or plate cam is a type of cams in which follower moves radially from the center of rotation of the cam. These cams are very popular due to their simple design and compactness that can be fitted into remote places.
How does a follower work on a wedge Cam?
The motion of the follower is specified by the groove or contour. A wedge cam has an angled flat regular contour so that a specific motion can be imparted to the follower. Spiral cams have a half-circular or a spiral shaping grooved contour, allowing it to move in a reciprocating motion. The follower moves vertically to the axis of the cam.
