Whether dealing with heavy loads or high-speed precision, understanding the different types of bearings is necessary to keep operations running smoothly. Here are six common bearing types and their unique roles across various industries.

Modern industry relies on various bearing types to keep machinery running smoothly. From mining and manufacturing to transportation and agriculture, bearings ensure the reliable performance of heavy-duty equipment. Bearings are critical in facilitating movement and handling mechanical loads across multiple sectors.

In this article, we will explore six common bearing types and their specific applications, from traditional ball bearings to advanced roller designs, demonstrating how they contribute to the efficient operation of industries worldwide.

What are bearings, and how do they work?

Bearings are critical components in a wide range of industrial equipment. Thousands of essential items could not function without them. Bearings are tribological components, defined as interacting surfaces involved in relative motion. Other examples include seals, piston rings, and electrical brushes.

Design elements

Bearings come in many shapes and sizes and are designed to support a specific type of motion. Depending on the wider system and its loading and movement demands, they are confined to limited degrees of freedom. Bearings are used for different applications and have several standard design features.

• They have three parts, with a rolling element between the inner and outer rings.
• The ring arrangement is called a “raceway”, and rolling elements include either balls or rollers.
• Along with these central components, bearings also include a cage, which retains the rolling element to prevent unwanted impacts and movement.

The elements are designed with a very specific purpose: to reduce friction and support loads. They prevent direct metal-to-metal contact between elements in relative motion, reducing wear and tear and energy consumption.

They also affect weight distribution, moving the load to the housing instead of the rotating element.

Types of uses: Where bearings are found

Bearings are found in a wide range of products. There are thousands in railway stock, aircraft engines, and wind turbines. Bearings are extremely common in industrial machinery, from motors and gearboxes to pumps and conveyors. They are central in numerous machinery classes and are used daily across multiple industry sectors.

Manufacturing, oil and gas, construction, and marine industries rely on heavy-duty machinery. Depending on the application, various bearing designs are suitable for these sectors. For example:

• Thrust ball bearings provide rigidity to sustain higher axial loads.
• Tapered roller bearings are also standard, especially for commercial vehicle applications.
• Hydro-static bearings are another example, and this design can support heavy loads by limiting relative motion.

Applications of bearing types in various industries

Depending on the type of structure and surrounding machinery, bearings offer many benefits. Industries use proven designs to support specific use cases and operating environments.

When the right bearings are selected for the task at hand, operators can expect the following benefits:

• Enhanced operational efficiency
• Increased equipment lifespan
• Reduced maintenance costs

Along with these general benefits, there are also industry-specific advantages:

• Mining: Bearings support high loads and extreme operating conditions.
• Manufacturing: Bearings enable design precision and promote durability.
• Oil and gas: Bearings can be used in high-pressure environments.
• Construction: Bearings enable heavy-duty performance in all conditions.
• Agriculture: Bearings are durable in harsh environments and weather.
• Wind energy: Bearings can be used in extreme operating conditions.

The six bearing types you need to know

Different bearing types are designed to support different applications. While the basic configuration of each bearing is the same, the rolling element and ring structure can be designed in various ways. The following bearing types are common:

Ball bearings

The most familiar is the ball bearing type, with a row of balls used as the rolling element. The balls are trapped between metal pieces known as races, with the outer race stationary and the inner race free to rotate. Ball bearings provide very low friction, so they are ideal for centrifugal pumps and railroad axles, among other applications.

There are many types of ball bearings, including deep groove ball bearings, thrust ball bearings, self-aligning ball bearings, and angular contact ball bearings.
