Eccentric cam followers, also known as eccentric track rollers or eccentric stud-type cam followers, are a specific type of cam follower bearing designed with an eccentric collar or stud. These cam followers are used to transmit motion in mechanical systems where the follower's position needs to be adjusted or changed along the cam profile.

The key feature of eccentric cam followers is the eccentric collar or stud, which allows for fine adjustments of the follower's position relative to the cam or track. This eccentric feature enables changes in the radial position of the cam follower, allowing for precise control of motion or clearance adjustments.

Here are some important characteristics and applications of eccentric cam followers:

Eccentric Collar or Stud: The eccentric collar or stud is typically positioned off-center relative to the bearing axis. By rotating the eccentric element, the position of the cam follower can be adjusted, altering its radial position.

Adjustability: Eccentric cam followers are used when the follower's position needs to be fine-tuned along the cam profile. This adjustability is beneficial for applications where accurate alignment or clearances are crucial.

Applications: Eccentric cam followers find applications in various industries, including packaging machinery, printing equipment, conveyor systems, material handling equipment, and more. They are used in situations where precise alignment or tensioning is required.

Load Capacity: The load capacity of eccentric cam followers depends on factors such as the design, size, and materials used. Proper selection is essential to ensure that the cam follower can handle the specific loads and forces in the application.

Lubrication: Like other cam followers, proper lubrication is important for the smooth operation and longevity of eccentric cam followers.

Mounting: Eccentric cam followers are typically mounted using the stud or shaft end, and they may include flanges or other mounting features.

Eccentric Collar Locking: Eccentric cam followers can have an eccentric collar that locks the bearing onto the shaft by tightening a locking nut or set screw. This locking mechanism secures the cam follower in place after adjustments are made.

It's important to consult the manufacturer's specifications and guidelines when selecting and using eccentric cam followers, as their features and applications can vary between different models and manufacturers. Eccentric cam followers are chosen based on specific requirements for adjustability, load capacity, environmental conditions, and other factors within the intended application.
