What Are the Different Types of Flange Bearings?

In the simplest terms, bearings are used to reduce friction between two mating parts. They do this by bearing force, load, or both typically on to a shaft of plate. Bearings come in a variety of shapes, sizes, and materials; as different applications require different types of bearings. One specialized type of bearing is the bronze flange bearing.

Flange Bearing Design

What sets flange bearings (sometimes known as flanged bushings) apart from other types of bearings is that at least one end is flanged, while the other may be straight. When it’s a single flange bearing, its shape resembles that of a top hat.

The flange (or lip) of the Flange Bearing holds the bearing in place to prevent shifting, slipping, or falling while the bearing is in use. This is particularly important when there is axial push or load being applied and when shafts run perpendicular to the bearing’s mounting surface. Flanged bearings are used to reduce issues from vibration, shaft flexing, and axial overload due to high speeds and heavy loads. Another benefit of a flange bearing, as opposed to other types of bearings, is that their design allows them to withstand high temperatures because they are held in place by the flange even when thermal expansion is occurring.

Without the lip on the end of a flange bearing, the machinery would stop working shortly after starting, as the bearing would fall out of place. Although a flange may seem inconsequential, it is actually a critical component of the design of these types of bearings.

Types of Flange Bearings

Flange bearings have at least one flange on an end of the sleeve, but beyond this, they are made from many different types of metals and plastics because they all have specific qualities, depending on the application. For instance, Flange Bearings made from Oil-impregnated Bronze release oil when in operation, making them relatively maintenance-free. Or a flange bearing made from C86300 that has graphite plugs may be used because its self-lubricating and can handle temperatures upwards of 700 degrees.

At Atlas Bronze, we provide a range of flanged bronze bushings from standards that are in stock and off the shelf to custom machined with graphite-plugs, or machined with groove used for oil and grease lubrication.

Choosing which flange bushing can be complicated. But we can help.
