Track bearings for underwater vehicles

Track Bearings for Underwater Vehicles

Track bearings play a crucial role in the smooth operation of underwater vehicles. These specialized bearings are designed to withstand the harsh underwater conditions and provide reliable support for the vehicle’s track system. In this article, we will explore the various aspects of track bearings and their importance in underwater vehicles.

1. Understanding Track Bearings

Track bearings, also known as track rollers, are mechanical components that support and guide the movement of the vehicle’s tracks. They are typically cylindrical in shape and consist of an outer ring, inner ring, rolling elements, and a cage. These components work together to ensure smooth and efficient track operation.

Track bearings are designed to handle both radial and axial loads, making them ideal for underwater vehicles that operate in challenging environments. They are often made of high-quality materials such as stainless steel or corrosion-resistant alloys to withstand the corrosive effects of saltwater.

2. Types of Track Bearings

There are various types of track bearings available for underwater vehicles, each with its own unique characteristics and advantages. Here are some commonly used types:

2.1. Stud Type Track Bearings

Stud type track bearings are designed with a stud that extends from the outer ring, allowing for easy installation and removal. They are commonly used in underwater vehicles where frequent maintenance or replacement is required.

These bearings are highly durable and can handle heavy loads, making them suitable for demanding underwater applications. They are available in different sizes and configurations to meet specific vehicle requirements.

2.2. Yoke Type Track Bearings

Yoke type track bearings feature an inner ring with a hardened raceway that provides a smooth rolling surface for the vehicle’s tracks. They are designed to handle both radial and axial loads and are commonly used in underwater vehicles that operate in rough terrains.

These bearings are known for their high load-carrying capacity and durability. They are available in various designs, including sealed and unsealed versions, to suit different environmental conditions.

3. Advantages of Track Bearings

Track bearings offer several advantages for underwater vehicles. Here are some key benefits:

3.1. Enhanced Durability

Track bearings are built to withstand the harsh conditions of underwater environments. They are resistant to corrosion, impact, and wear, ensuring long-lasting performance even in challenging situations.

3.2. Smooth Operation

By providing reliable support and guidance to the vehicle’s tracks, track bearings enable smooth and efficient movement. This helps minimize friction and energy loss, resulting in improved overall performance.

3.3. Increased Load Capacity

Track bearings are designed to handle heavy loads, making them suitable for underwater vehicles that require robust support. They distribute the load evenly, reducing stress on individual components and enhancing the vehicle’s carrying capacity.

4. Application of Track Bearings

Track bearings find extensive use in various underwater vehicle applications. Some common examples include:

4.1. Remotely Operated Vehicles (ROVs)

ROVs are unmanned underwater vehicles used for various purposes, such as underwater inspection, exploration, and maintenance. Track bearings are essential components in ROVs, providing reliable support and maneuverability.

4.2. Autonomous Underwater Vehicles (AUVs)

AUVs are self-propelled vehicles used for underwater surveys, mapping, and scientific research. These vehicles rely on track bearings to ensure precise control and smooth movement in challenging underwater conditions.


In conclusion, track bearings are essential components in underwater vehicles, providing reliable support, smooth operation, and increased load capacity. Their durability and performance make them integral to the efficient functioning of underwater vehicles in various applications.
