Understanding the Fundamentals of Flange Bearing Technology

Flange bearings are a type of an angular contact bearing that is used in a vast number of industrial applications. Every flange bearing consists of two flanges that hold a bearing together. The two flanges are connected to each other via four fasteners that keep the bearing together. The bearing is then bolted onto the component that needs to rotate.

Benefits of Flange Bearing Technology

Flange bearings provide a number of perks including:

  • Easy Installation: Flange bearings are relatively easy to install as they can be easily bolted onto the equipment. This makes them a preferred choice for many industries.
  • High Durability: Flange bearings are made from the highest quality materials and are designed to be durable and reliable.
  • Noise Reduction: Flange bearings produce minimal noise which makes them ideal for use with sensitive components.
  • Low Maintenance: The robust design of flange bearings means they require minimal maintenance.

How Do Flange Bearings Work?

Flange bearings are composed of an inner and outer ring with two adjoining races or flanges. The inner ring is secured to the shaft with a locking nut and the outer ring is bolted to the component or equipment that needs to rotate. As the component rotates, the inner raceway will rotate similarly.


Flange bearings are a type of angular contact bearing that offers a wide range of benefits, including easy installation, high durability and low maintenance. They are composed of two adjoining races and are secured to the component or equipment needing to rotate. Flange bearings are commonly used in a variety of industries due to their robust design and reliability.
