Enhancing Industrial Efficiency with Housed Bearing Units

In the world of industrial machinery and equipment, there are countless components that work together to ensure smooth and efficient operation. One such vital component that often goes unnoticed but plays a critical role in ensuring the reliability of these systems is the housed bearing unit

Let's explore what housed bearing units are, their types, their applications, and why they are essential for various industries.

What Are Housed Bearing Units?

Housed bearing units, often referred to as bearing housings or pillow blocks, are assemblies that consist of a bearing and a housing. The housing provides a secure and protected environment for the bearing, allowing it to operate efficiently and with a longer lifespan. This combination of a bearing and housing simplifies the installation and maintenance of bearings, making them a popular choice in industrial settings.


There are several types of housed bearing units, each designed to meet specific application requirements. The most common types include:

Pillow Block Bearings

These are the most popular types of housed-bearing units. They are designed with a pillow-shaped housing that is easy to install and maintain. Pillow block bearings are used in a wide range of industries, including agriculture, manufacturing, and material handling.

Flange Bearings

Flange bearings are designed with a flange-shaped housing that allows them to be easily bolted to a surface. They are commonly used in applications where space is limited or where precise positioning is required.

Take-Up Bearings

Take-up bearings are designed to allow for axial adjustment. This makes them ideal for applications where the distance between the shaft and the mounting surface can change, such as conveyor systems.

Cartridge Bearings

Cartridge bearings are pre-assembled units that are often used in high-speed applications. They are designed for easy installation and provide excellent sealing, reducing the risk of contamination.

Applications of Housed Bearing Units

Housed bearing units from Bolton Engineering Products find application in a wide range of industries due to their versatility and reliability. Some common applications include:


In the agriculture sector, housed bearing units are used in machinery such as tractors, combines, and ploughs, ensuring reliable and efficient operation.


The manufacturing industry relies heavily on housed bearing units for conveyor systems, material handling equipment, and various machinery.


In the mining industry, these units are used in crushers, conveyors, and other equipment that operates in harsh and demanding conditions.

Food and Beverage

Housed bearing units are essential in food and beverage processing equipment, where hygiene and precision are paramount.


Automotive manufacturing and assembly lines use housed bearing units in robots, conveyors, and other machinery.


Housed bearing units are found in construction equipment, including cranes, excavators, and concrete mixers.

Advantages of Housed Bearing Units

The use of housed bearing units offers several advantages for industrial applications:

Easy Installation

Housed bearing units come pre-assembled, making installation straightforward and reducing downtime.


The housing protects the bearing from contaminants, moisture, and physical damage, extending the bearing's lifespan.

Reduction in Maintenance

Housed bearing units are designed for durability and require less frequent maintenance, contributing to lower operating costs.


With various types available, housed bearing units can be customized to suit specific application requirements.

Increased Efficiency

Reliable housed bearing units contribute to smoother machinery operation and increased overall efficiency.

Choosing the Right-Housed Bearing Unit

Selecting the right housed-bearing unit is crucial for the success of an application. To make an informed choice, consider factors such as load capacity, speed, environmental conditions, and required maintenance.

Load Capacity

Ensure that the housed bearing unit can handle the anticipated loads without compromising performance or bearing life.


Different housed bearing units are designed for different speeds. Choose one that matches your application's speed requirements.

Environmental Conditions

Consider the operating environment, including temperature, moisture, and the presence of contaminants. Choose a unit with appropriate sealing and protection features.

Maintenance Needs

If your application demands minimal maintenance, opt for housed-bearing units designed for durability and reduced upkeep.


Some applications may require specialized designs. In such cases, work with a bearing supplier to find or customize the right housed bearing unit for your needs.


Housed bearing units are indispensable components in various industries, providing reliable support for rotating shafts and reducing maintenance efforts. By understanding the different types, applications, and advantages of housed bearing units, you can make informed decisions when selecting the right unit for your machinery. Choosing the right housed bearing unit from Bolton Engineering Products not only ensures efficient operation but also contributes to the longevity and productivity of your equipment.
