All About Bronze Flanged Bearings

Flanges feature a projecting rim over the edge of another part, a collar to secure connecting pieces together, or a ring to provide pressure to holds components in place. They enable part fabricators to customize the function of end products for customers.

Ultimately, flanges provide strength and stiffness at more vulnerable areas of a part and facilitate the connection of diverse components. They are also useful in mounting and positioning static items. When paired with bearings on the external housing of a device, flanges increase the ability of the end product to effectively handle radial and thrust loads.

Flanges are one of the most popular types of bearings requested by our clients at Bunting Bearings. This introduction to bronze flanged bearings will help readers understand what they are and what they can do for industrial manufacturing and assembly projects.

The Benefits of Bronze

Bronze alloys predominantly consist of copper and tin. Additional metals are added to the mix – i.e. aluminum, manganese, nickel, or zinc – to achieve the desired metallurgy. This results in a bronze material with ideal physical properties to suit the needs of the end application. For example, bronze can be tailored to have a specific physical appearance and offer better protection for end components against corrosion and surrounding conditions like moisture.

Bronze bearings and bushings are made to be rigid and tough. In comparison to those made of brass, bronze parts last longer and hold their shape better under repeated use. Bronze greatly improves resistance to:

  • Impact
  • Shock
  • Corrosion
  • Mechanical wear-and-tear

This means that bronze bearings last longer than their softer and more malleable brass counterparts. Bronze also causes less friction when brought in contact with other metal parts, which helps to extend the life of the bearing.

Applications and Advantages of Bronze Flanged Bearings

The versatility of bronze flanged bearings makes them an ideal fit for a number of industrial applications. Bronze flanged bearings are known for their low-maintenance durability. Heavy-duty industrial operations that rely on low-speed, high-load processes are particularly good candidates for bronze flange bearings, which hold up well under immense and repeated pressure.

Bronze flanged bearings are often found in equipment used in:

  • Iron and steel manufacturing
  • Food processing
  • Injection molding
  • Automotive equipment
  • Earth movers
  • Industrial pumps

The additional metal alloys that make up the bronze impart beneficial characteristics to the resulting material. Some of the common alloys used for bronze flanges include:

  • Oil is infused into the alloy via powder metallurgy. Depending on its composition, SAE841 can accommodate for a wide range of speeds and temperature ranges. It is often used in food-grade applications.
  • Aluminum, tin, and silicone. Marine manufacturers value the high corrosion-resistance of copper, but must alloy the copper with other materials to improve its strength. Copper alloyed with aluminum, tin, or silicone creates a bronze that enables manufacturers to create water-tight vessels without excessive weight.
