Flange bearings are essential components in many industries. They play a key role in holding machines, engines, and mechanical systems together. In order to ensure optimal performance, it is important to understand how flange bearings work and the various types available. This guide will provide an overview of flange bearings and help you make the right choice for your application.

What Is a Flange Bearing?

A flange bearing is a type of bearing that is designed to hold rotating objects in place. It consists of an inner ring, an outer ring, and a set of balls between the two rings. The inner and outer rings are mounted to the parts they are holding in place and the balls provide an easy way for the outer ring to turn with respect to the inner ring.


There are several types of flange bearings available, each designed for specific applications. These include:

  • Split Flange: A split flange bearing is composed of two rings that are clamped together, making it easy to install and remove.
  • Slide Flange: This type of bearing uses a sliding motion rather than balls to hold the two rings together. This makes it ideal for applications that require a lot of rotation or tilting.
  • Plain Flange: Plain flange bearings are the most common type and consist of two flat rings that are connected by bolts and screws.
  • Roller Flange: These bearings feature two rings connected by rolling elements, providing both high loads and low-friction movement.


When choosing a flange bearing, it is important to consider the application and the type of environment it will be used in. Some key factors to consider include:

  • Load requirements
  • 環境条件
  • Appropriate size and dimensions
  • 料金

By considering these factors, you can make sure you have the right type of flange bearing for your application and won’t have to worry about sacrificing performance or quality.


Flange bearings are essential parts of many rotating assemblies. They provide support and enable a wide range of movements. Understanding how flange bearings work and the different types available will help you make the right choice when selecting a bearing for your application.
