What Are Flange Bearings?

Bearings are for industries what cells are for our bodies. The majority of the machinery shall be rendered useless if the necessary bearings are absent or flawed. For a tool of this importance, it is also pertinent to be tailored to specific uses. Likewise, bearings, as a product, have multiple variants ranging from ball bearings to roller bearings.

Furthermore, to accommodate specific uses in the fields of automobile and textile, bearing manufacturers have developed a design variant. And it is known as Flange Bearings.

Let's understand the characteristic of Flange bearing in detail:


 

Design:

Generally, bearings have a symmetric shape to maintain stability and work effectively. Unlike them, flange bearings have two different ends. They have one straight end and another end with a lip or what the bearing manufacturing company calls — a flange.

The durability of flange bearings is high, courtesy of the fact that they are mounted. These bearings are mounted with two, three, or even four bolts. This provides the flange bearings with the ability to support heavy loads.

Flange bearings are designed to support the load when the shaft axis is perpendicular to the mounting surface. In this direction, flexing of the shaft and severe vibration are common. If left unattended, this spells doom for the entire machine.

To solve this, flange bearings are installed to support the shaft. Adding on, flanges also solve the problem of improper positioning of the bearing. By aligning the bearing during installation, locks the bearing and prevents it from any axial movement.

Alongside the prime objective of reducing friction, flange bearings help the machines in several ways. It secures the machine’s stability while allowing it to run seamlessly for a longer period.

 

Types:

By standard, flange bearings are three inches or slightly less in diameter. Yet, there are a few shapes in which flange bearings can be produced. In the application of flange bearings, there is no one-size-fits-all answer.

Hence, bearings and bushes suppliers produce flange bearings in three major types. These are based on the number of bolts used to mount the bearings.

 

  • Two-bolt flange bearings

These generally come in a diamond shape and are tailored to bear intermediate loads. The two-bolt flange bearings are designed with a substantial volume tolerance. Hence, machines that accommodate medium loads at a consistent volume are ideal for the installation of these bearings.

  • Three-bolt flange bearings

Flange bearings with three-bolt are pretty common. These bearings are used extensively in industries like automotive and agriculture. Usually, they are in a triangular or circular shape. The three-bolt flange bearings are not known for supporting heavy loads. But, for machines with light to medium loads, these are ideal even at high volume.

  • Four-bolt flange bearings

One of the sturdiest amongst bearings and bushings, the four-bolt flange bearings can handle heavy loads. Generally, they are produced in round or square shapes. Adding on, they provide a very stable base for machines with rotating or linear movements.

The automobile industry employs the four-bolt flange bearings at a large scale.

 

Materials:

The alloys and materials used to produce flange bearings are several. They are usually selected based on the bearings’ application. To add perspective, here are three common materials used to produce flange bearings.

 

  • Bearing Bronze

This material encompasses a variety of alloys and elements. The majority i.e. nearly 85% of this material is copper. Alongside, lead and tin are some notable elements found in bearing bronze.

Despite the varying alloying elements, the density of bearing bronze remains consistent. Bearing bronze has an incredible capacity to resist heat, making them almost non-responsive to heat treatment.

Flange bearings used for light to medium load applications are best suited to be made using bearing bronze.

 

  • Metal Polymer

This material is used for flange bearings that can operate in dry conditions. They offer top-standard anti-friction resistance while reducing wear and tear.

They have a metal-dominant structure with a sintered layer of bronze. To further the efficacy of the bearings, thermoplastic is overlaid. This overlay increases the fatigue strength of the bearings by a fair margin.

Since this material is customized, it is flexible enough to manage various loads and volumes.

 

  • Aluminum Bronze

These are copper-based alloys made of iron and nickel. Yet, aluminum is used as the major alloying element. This composition makes the aluminum bronze material — one of the best performing materials.

They are stronger than low alloy steels, whilst being resistant to corrosion. Aluminum bronze material is also known for its longevity.Flange bearings used in high-load applications are ideally made of aluminum bronze.

 

Conclusion:

If you are looking for flange bearings, don’t look any further. With Hi-Bond, you are investing in the pioneers of bearing manufacturing. All bearings and bushes produced are tailored to your needs.
