Which Flange Bearing Is the Best?

 

The flange bearing is a specialized type of bearing that has a lip on one side. Like all bearings, a flange

bearing functions to reduce friction between two parts. Bearings come in a wide range of sizes, shapes,

and materials and they may bear force, load, or a combination of the two, but the flange bearing is one

of the most frequently used varieties.

What Is a Flange Bearing?

A flange bearing is built differently than other bearings because one end is straight, while the other has a lip (or flange). 


Also known as a flanged bushing, a flange bearing provides more stability in an application. The flanged side secures the bearing while it’s being used, preventing it from falling, shifting, or slipping. This is critical in applications that involve axial push or load and when shafts are perpendicular to the mounting surface of the bearing. Without the flange end, an application would quickly malfunction because the bearing would slip out of position.


Flanged bearings also serve to minimize shaft flexing, vibration, and axial overload when heavy loads or high speeds are involved. Because a flange bearing is secured in place, it has the ability to withstand high temperatures that cause thermal expansion, which would compromise other types of bearings.

Determining the Best Types of Flange Bearings

Which flange bearing is best? There’s really no one-size-fits-all answer to this question. The best flange bearings are the ones that meet the needs of your application.


Although all flange bearings are similar in design, with flanges on one end, the similarities end there. There are several types of flange bearings, starting with the number of bolts needed to secure them in place:

  • Two-Bolt Flange Bearings are best used for machinery with intermediate shaft speeds and load sizes. They have a wing or diamond shape.

  • Three-Bolt Flange Bearings are the bearing of choice for industrial, agricultural, and automotive applications with light-to-medium loads. The flange-end is usually circular. 

  • Four-Bolt Flange Bearings have a great deal of stability, making them ideal for applications with rotating or linear movements or when a mounting surface is perpendicular to the shaft. They are square or circular in shape.

Beyond the bolt number and configuration, flange bearings can be differentiated by the materials used to make them. Oil-impregnated flange bearings release lubrication when under pressure and reabsorb it once the pressure is released, which is why they’re the preferred choice for applications that must be maintenance-free. You might find flange bearings mounted in thermoplastic, stainless steel, or cast iron housing. Each of these materials is suitable for different types of surfaces, machinery, and applications.


We offer a wide range of flange bronze bearings, including plain, graphite-plugged, and oil or grease grooved.

The Differences Between Copper and Bronze


There’s quite a bit of overlap in the qualities and uses of copper and bronze, but there are also some

significant differences you should be aware of if you’re choosing between the two metals for your

application. What’s the difference between copper and bronze? Which one is the best choice for

your needs? We answer these questions below.

Understanding Copper

Copper is one of the earliest metals used by human populations. Best known for its reddish hue, copper is the term used for both pure copper and any copper alloy that has at least a 99.3 percent copper content. You’ll find copper in sculptures, architecture, and fixtures, but behind the scenes, it’s also commonly used for heating and electrical applications because of its superior conductivity.


There are other reasons to choose copper for your application besides conductivity, though. Copper is resistant to corrosion and valued for its strength. It’s highly formable, which is likely why it was such a widely used material by early humans. Copper is antimicrobial, making it suitable for many healthcare and medical uses. Architects, sculptors, and other artists appreciate copper because it can be given different lusters and textures when it’s buffed and polished.

Understanding Bronze

Bronze is a metal alloy that is made mostly with copper, but not enough to be considered a copper alloy. In addition to copper, other metals like iron, zinc, and tin are added to impart different qualities on the resulting metal. Like copper, bronze is often used in statues, sculpture, and architecture. Its industrial uses include pump parts, bearings, gears, and valves because bronze is valued for its resistance to wear and low friction. Many musical instruments are also made with bronze.


Bronze cast alloys, like those available from Atlas Bronze, are manufactured in three different ways: sand casting, centrifugal casting, and continuous casting. Different casting methods are used for different types of products and parts.

Copper vs. Bronze: What Makes Them Different?

Here are some of the notable qualities of copper and bronze, and differences between the two metals.


  • Bronze is a dull gold in color, while copper is more of a reddish-orange.

  • Copper is more commonly used in wiring and pipes, while bronze is a popular choice for bushings and bearings.

  • Bronze alloys are resistant to corrosion and known for their strength, while copper is malleable and easily soldered.

  • Copper can be an alloy and also a natural element, while bronze is always an alloy.

  • Bronze has low friction, which makes it an excellent choice for moving parts.

  • Copper has antimicrobial properties, which makes it ideal for high-touch surfaces and healthcare settings.
