What Are Mounted Bearings Used For?

Mounted bearings play a crucial role in various machinery and equipment. These versatile components support a rotating shaft and are essential for a wide range of applications across different industries. In this article, we'll explore the types of mounted bearings and their uses. Learn why they are essential for both heavy-duty applications and precision tasks.

Understanding the types and functionality of mounted bearings helps you select the right one for your needs. This knowledge prevents premature bearing failure and ensures the longevity and efficiency of your machinery. 

Types of Mounted Bearings

Before we discuss the uses of mounted bearings, it's important to understand the different types available.

Pillow Block Bearings

Also known as plummer blocks, these are the most common type of mounted bearing units. They are typically mounted in a clean environment on a surface parallel to the shaft axis. Pillow blocks are made of cast iron or steel and provide support for rotating shafts.

Flange Block Bearings

Flange mounted bearings come in various forms, including square, oval, or round, with two, three, or four mounting holes. They are used when the shaft axis is perpendicular to the mounting surface. Flange block bearings include mounting flanges that secure the unit to the surface.

Flange Block Bearing 

Bearing Inserts

These are replaceable components that fit inside the housings of pillow block and flange block bearings. Mounted bearing inserts allow for easy replacement and maintenance without needing to replace the entire mounted unit.

Applications of Mounted Bearings

Mounted bearings are used in various applications, ranging from simple conveyor belts to complex machinery. Their ability to different tasks makes them valuable in many sectors, including heavy-duty applications.

Manufacturing Equipment

Mounted bearings are extensively used in manufacturing equipment such as conveyors, motors, and various machinery. They provide support and reduce friction, enhancing the efficiency and lifespan of the equipment. Their ease of maintenance and ability to handle high loads make them ideal for manufacturing settings.

Agricultural Machinery

In agriculture, like agricultural bearings, mounted bearings are found in tractors, combines, and other equipment. They are favored for their durability and ability to withstand harsh conditions like dirt, moisture, and heavy loads. The simplicity of replacing these bearings in the field reduces downtime and maintenance costs.

Construction Equipment

Construction machinery, such as cranes, loaders, and excavators, relies on mounted bearings. These bearings help manage heavy loads and ensure operation in rugged environments. These bearings ensure the reliability and safety of the equipment by providing robust support and reducing wear and tear.

Food Grade Industry

In the food processing industry, mounted bearings must meet strict hygiene and safety standards. They feature an easy-to-clean design and often come with special seals and bearing lubricants to prevent dirt.

Mounted bearings are made from stainless steel or other corrosion-resistant materials. They ensure smooth and efficient operations in production lines, packaging machines, and other equipment while meeting health standards.

Conveyor Systems

Mounted bearings are integral to the operation of conveyor systems. They support the rotating shafts that allow belts and rollers to move products efficiently through a facility.

Medical Equipment

Mounted bearings are crucial in medical equipment such as diagnostic machines and patient handling devices. They demand high precision and reliability to ensure the safe and effective operation of medical devices. These bearings help maintain accuracy and performance over time.

Fans and Blowers

Fans and blowers rely on mounted bearings to ensure stable operation and to support the shaft that holds the fan blades or blower wheels. These bearings must be able to handle varying loads and speeds while maintaining precise alignment.

Medical Equipment

Mounted bearings are crucial in medical equipment such as diagnostic machines and patient handling devices. They demand high precision and reliability to ensure the safe and effective operation of medical devices. These bearings help maintain accuracy and performance over time.

Marine Applications

Marine environments pose unique challenges, including exposure to saltwater and high humidity. Mounted bearings used in boats and marine engines are designed to resist corrosion and withstand these harsh conditions. Their application ensures the longevity and reliability of marine equipment.

Preventing Premature Bearing Failures

Understanding how to properly install and maintain mounted bearings is key to preventing premature failures. Here are a few tips to keep in mind:

Correct Bearing Fitting

Improper fitting can lead to excessive vibration, heat, and wear. Ensuring the correct fit between the bearing and the shaft is critical for optimal performance and longevity.

Regular Maintenance

Routine inspections, proper lubrication, and cleaning can significantly extend the life of mounted bearings. Neglecting maintenance can result in bearing failures and costly downtime.

Environmental Factors

Environmental conditions such as dust, moisture, and corrosive materials can lead to bearing degradation. Selecting the right type of bearing and housing material, along with appropriate seals, can mitigate these risks.

Selection Criteria for Mounted Bearings

When selecting mounted bearings for your application, consider the following factors:

Load and Speed Requirements

The bearing must be able to handle the expected loads and rotational speeds without compromising performance or safety.

Shaft Size and Configuration

The bearing's inner diameter must match the shaft's diameter, and the mounting configuration should align with the machine's design.

Operating Environment

Select materials and bearing seals that can handle your operating environment's specific conditions. Consider factors like extreme temperatures, dirt, and moisture.

Maintenance Access

Select bearing units that can be easily accessed for maintenance, lubrication, and replacement to minimize downtime.

Conclusion

Mounted bearings are vital for smooth and efficient machinery operation, from heavy industrial loads to precise medical devices. Understanding the types, uses, and proper maintenance ensures reliability and longevity. Whether for high-speed shafts or food-grade applications, there's a mounted bearing to meet your needs.
