Track roller single-row bearings, also known as track roller bearings, are specialized rolling-element bearings designed for use in track-type or linear motion systems. These bearings are used in a variety of applications where linear or rotational motion is required along a defined track or rail. They typically consist of an outer ring with a track or rail on which the rollers run, and they can be categorized into two main types: cam followers and yoke-type track rollers.

1. Cam Followers: Cam followers have a stud or shaft that extends from the center of the bearing. The outer ring of the bearing has a groove or track that the rollers follow. Cam followers are used in applications where the bearing needs to rotate about its own axis while following a track. They are available with different designs, including stud-type and eccentric stud cam followers, to suit various applications.
2. Yoke-Type Track Rollers: Yoke-type track rollers have a yoke or stud that extends from the outer ring, and they are designed to follow a track or rail while maintaining a fixed orientation with respect to the track. They are commonly used in applications where the bearing remains stationary relative to the track, and the track itself moves. Yoke-type track rollers come in various configurations, including with an eccentric bushing or a hexagonal socket for ease of installation.

Key features and characteristics of track roller single-row bearings include:

• High Load-Carrying Capacity: These bearings are designed to handle both radial and axial loads.
• Durable Construction: Track roller bearings are constructed to withstand the rugged conditions and repetitive linear or rotational motion of track-type applications.
• Sealed and Shielded Options: Many track roller bearings come with seals or shields to protect against contamination and retain lubrication.
• Maintenance-Free Options: Some track roller bearings are designed to be maintenance-free, reducing the need for relubrication and servicing.

Track roller single-row bearings are used in a variety of applications, including:

• Material Handling Equipment: In conveyor systems, linear motion guides, and lifting equipment.
• Agricultural Machinery: In farm equipment such as harvesters, balers, and plows.
• Packaging Machinery: In packaging and filling equipment, as well as labeling and sorting machines.
• Printing Machinery: In printing presses and paper transport systems.
• Automated Manufacturing: In robotic systems, CNC machines, and linear actuation systems.
• Textile Industry: In textile machinery for thread guiding and tension control.

When selecting track roller single-row bearings, it’s important to consider factors such as the load requirements, speed, temperature, and environmental conditions of the application to ensure that the bearing meets the desired performance criteria.
