The Essential Guide to Flange Bearings

Flange bearings provide a simple, lightweight solution for many applications. They are cost-effective, long-lasting, and require minimal maintenance. This article will explore the essentials of flange bearings, and provide some tips on how to select the right type for your application.

What are Flange Bearings?

Flange bearings are essentially a combination of a bearing and a mounting component. They provide a sturdy connection between two parts, such as a motor and a drive shaft. The bearings are usually made from flexible plastic or metal, and contain internal lubrication to reduce heat and friction.

Types of Flange Bearings

There are a variety of flange bearings available for different applications. Some of the most common include:

  • Radial Bearings: These bearings are typically used to support rotating shafts and provide radial rigidity. They come in a variety of sizes and materials.
  • Roller Bearings: These are excellent for applications with high loads, and can support heavier weights than other types of bearings.
  • Thrust Bearings: These are designed to handle axial loads and can be used in applications such as conveyors and motors.
  • Oil-impregnated Bearings: These bearings are designed to handle high speeds and temperatures, and are often used in motors and compressors.

Selecting the Right Flange Bearing

When selecting the right flange bearing for your application, there are a few key factors to consider:

  • Load: Consider the amount of weight that the bearing needs to support. This will determine the type and size of the flange bearing.
  • Speed: The speed at which the bearing will operate will also affect the selection. Choose a bearing type capable of withstanding the stresses of the intended operating speed.
  • Cost: Consider the total cost of the bearing, taking into account factors such as materials, installation, and maintenance.


Flange bearings are a great choice for many applications. By understanding the different types available and carefully considering the load, speed, and cost, you can ensure you make the right selection for your application.
