Understanding their uses and benefits

Flanged ball bearings play a crucial role in many industrial applications, thanks to their unique design and versatile functionality.

Bearings with a flange on the outer ring are easier to mount in a housing than standard bearings because they reduce reliance on housing tolerance for secure placement. This flange works as a stabilising feature, ensuring the bearing remains firmly in position even under axial loads or during vibrations.

 

Key advantages

Although flanged ball bearings are initially more expensive than their non-flanged counterparts, they offer significant advantages. This type of bearing is often favoured for its stability, reliability and ease of mounting:

  • Prevents movement: The primary function of the flange is to prevent movement in the axial direction. This feature is particularly beneficial in environments where bearings are subjected to fluctuating forces or continuous vibrations

  • Handles temperature fluctuations: The flange compensates for changes in housing fit because of thermal expansion. When temperatures fluctuate, materials expand or contract, potentially loosening a standard bearing. However, a flanged bearing remains secure, making it an ideal choice for applications with temperature variability

 

Types of flanged bearings

Deep groove flanged bearings

Deep groove ball bearings are among the most common types of bearings, known for their ability to handle radial and axial loads. When a flange is added, these bearings become even more versatile, providing added stability in demanding applications. Deep groove flanged bearings are particularly useful in machinery requiring high-speed rotation.

 

Applications of flanged bearing

Automation and robotics

In automation systems, precise movement and stability are critical. Flanged bearings are commonly used in robotic arms and conveyor systems to ensure smooth and reliable operation.

Aerospace and automotive

In aerospace and automotive industries, flanged bearings provide stability and resistance to vibrations, ensuring critical components perform reliably under demanding conditions.

Manufacturing and processing machinery

Flanged bearings are used extensively in manufacturing environments, from packaging machines to assembly lines. Their ability to handle axial loads and maintain alignment under stress makes them invaluable.

 

Materials and coatings

Flanged bearings are available in various materials to suit specific applications. Common options include:

  • Stainless steel: Resistant to corrosion, making it ideal for food processing or marine environments.

  • Ceramic: Lightweight and capable of withstanding high temperatures, suitable for aerospace applications.

  • Plastic: Lightweight and corrosion-resistant, often used in environments requiring hygienic conditions.

 

Maintenance and longevity

Proper maintenance is essential to maximise the lifespan of flanged bearings. Regular lubrication is critical to minimise friction and prevent wear. Inspecting the bearing for signs of wear, such as noise or vibration, can help identify issues early and avoid costly downtime.

 

Flanged bearings vs. standard bearings

Ease of installation

Flanged bearings simplify the installation process by reducing the need for precision housing fits. The flange ensures the bearing stays in position, even in less-than-ideal conditions.

Stability under axial loads

Standard bearings can shift or become misaligned when exposed to axial forces. Flanged bearings prevent this movement, providing superior stability.

Cost versus performance

While these bearings can be more expensive upfront, their performance advantages often outweigh the initial cost, particularly in applications requiring long-term reliability.
