Cam Followers

What is a Cam Follower?

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.

What are the different types of cam follower?

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.

What is the difference between a studded cam follower and a roller follower?

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.

How do I Choose the Correct Cam Follower?

To choose the correct cam follower, follow these steps:

1. Understand the application: Determine the specific requirements of your application, such as load capacity, operating conditions (speed, temperature), and environmental factors (dust, moisture).
2. Identify the cam type: Different cam followers are designed for specific cam types, such as flat, radial, or crowned cams. Determine the type of cam you are using to ensure compatibility.
3. Consider load capacity: Calculate the maximum load that the cam follower will experience during operation. Choose a cam follower with a load capacity that exceeds this value to ensure reliability and longevity.
4. Select the appropriate size: Consider the cam follower's diameter, length, and stud size to ensure it fits within the available space and aligns correctly with the cam.
5. Evaluate lubrication requirements: Determine whether the cam follower requires lubrication or if it operates in a self-lubricating manner. Consider the lubrication method and intervals to ensure proper maintenance.
6. Check sealing options: Depending on the application, you might require a cam follower with appropriate sealing mechanisms to protect against contaminants or retain lubrication.
7. Consider special features: Some cam followers offer additional features, such as eccentric or adjustable studs, high-temperature resistance, or corrosion resistance. Assess whether any special features are necessary for your application.
8. Consult technical resources: Refer to manufacturers' catalogues, datasheets, or technical support to gather detailed information about different cam follower options, including specifications and performance data.
9. Compare alternatives: Evaluate multiple cam follower options based on their suitability, quality, availability, and cost. Consider factors such as durability, reputation of the manufacturer, and compatibility with other components.
10. Seek expert advice if needed: If you're unsure or have specific requirements, consult with an engineer, supplier, or industry expert who can provide guidance and help you make an informed decision. Email us at sales@taperedrollerbearings.co.uk for any technical questions.
