Cam follower bearings, also known as track followers, are mechanical bearings that are designed to follow the surface of a cam or track. These bearings consist of an outer ring, a needle roller or cylindrical roller set, a stud, and a thick-walled outer ring.
The stud of a cam follower bearing is typically threaded and can be easily mounted onto the application. The outer ring of the bearing is designed to ride along a cam or track, providing linear motion to the application.
Cam follower bearings are commonly used in applications where linear motion is required, such as in printing presses, conveyor systems, and packaging machinery. They are also used in cam-driven machines, where they follow the contour of the cam and transfer motion to the machine.
One of the key advantages of cam follower bearings is their ability to handle high radial loads and moderate axial loads. This makes them suitable for applications where there are high loads and the need for linear motion. Additionally, they are available in a variety of sizes and configurations, making them suitable for different applications.
Cam follower bearings are also designed to operate with minimal noise and vibration, which improves the overall performance and efficiency of the system. They are also highly customizable, with options for stud length, thread size, and lubrication.
Overall, cam follower bearings are a reliable and versatile solution for providing linear motion in a wide range of applications. They offer high-load capacity support, low noise and vibration, and are highly customizable to meet the specific needs of each application.
There are several benefits to using a cam follower bearing, including:
1). High load capacity: Cam follower bearings are designed to handle high radial loads and moderate axial loads, making them suitable for applications where there are high loads and the need for linear motion.
2). Versatility: Cam follower bearings are available in a variety of sizes and configurations, making them suitable for different applications. They are highly customizable, with options for stud length, thread size, and lubrication.
3). Low noise and vibration: Cam follower bearings are designed to operate with minimal noise and vibration, which improves the overall performance and efficiency of the system.
4). Easy installation: Cam follower bearings are easy to install and can be easily mounted onto the application using the threaded stud.
5). Long service life: Cam follower bearings are designed to provide long service life, even in high-load and high-cycle applications.
6). Low friction: Cam follower bearings provide low friction, which reduces wear and improves the efficiency of the system.
Overall, the benefits of using a cam follower bearing make them an ideal choice for providing linear motion in a wide range of applications. They offer high-load capacity support, low noise and vibration, versatility, easy installation, long service life, and low friction.
There are several different types of cam followers, each designed for specific applications. Here are some common types of cam followers:
Standard cam followers: These are the most common type of cam follower and are available in a range of sizes and designs, available in both metric and imperial. They have a thick-walled outer ring and a stud.
Roller followers: These have a cylindrical roller between the cam and the follower, which allows them to handle high radial loads.
Eccentric cam followers: The CFE series cam followers have an eccentric collar on the stud, which allows for adjustment of the radial clearance and can be used to adjust the preloading force, however the CFES series cam followers have a solid eccentric stud which allows for the same adjustment.
Miniature cam followers: These are small-sized cam followers, often used in delicate and precision applications.
The type of cam follower to use depends on the specific application requirements, such as load, speed, temperature, and environmental conditions.
A studded cam follower and a roller follower are two types of cam followers, and the main difference between them is the shape of the contact surface that engages with the cam.
A studded cam follower, also known as a yoke-style cam follower, has a flat, disc-like surface that makes contact with the cam. This surface is attached to a stud, which allows the follower to be mounted onto a surface using a threaded connection. Studded cam followers are commonly used in applications where the follower needs to be bolted onto a machine or where the follower needs to be adjustable.
On the other hand, a roller follower has a cylindrical or conical roller that makes contact with the cam surface. The roller rotates as it moves along the cam, reducing friction and wear. Roller followers are commonly used in high-speed and high-load applications, such as automotive engines, where the smoother operation and reduced wear of the roller provide a significant advantage.
In summary, the main difference between a studded cam follower and a roller follower is the shape of the contact surface that engages with the cam. A studded cam follower has a flat, disc-like surface, while a roller follower has a cylindrical or conical roller.

We've answered some of the most frequently asked questions about cam followers below:
A cam follower is essentially a roller or needle bearing used to follow a rotating cam's profile. The thick outer ring is effective in moderating the edge load due to mounting errors. Typically, they're known as cam followers but can also be referred to as needle bearings; crowned steel or stainless steel versions are also available. Their purpose is to provide accurate and consistent motion for machinery components such as cams, pumps, and valves.
To fit a cam follower, follow these steps:
Remember to consult the specific instructions provided by the manufacturer for your particular cam follower and engine model, as the installation process may vary slightly.
