2020 Complete Information of Flange Bearings [Quick]

flanged bearing

Flange bearings, also known as flange mounted bearings or flange units. People use flanged bearings to mount ball bearings to a perpendicular surface. The term ‘flange’ refers to a projecting flat rim, collar, or rib on an object, serving for strengthening or attachment or for maintaining position on a rail.

When people use flange bearings, install the sealed bearing inside a preassembled flanged bearing housing. It allows the inner ring to rotate freely within a robust and stable environment.

Flanged Bearings Types

There are many different types of flanged bearings, all engineered for a specific application and all with different designs and cages, as well as load and performance capabilities. All flange bearings, however, have highly robust and resistant to water or contaminants. This makes them ideal for supporting heavy loads such as additional mounted apparatuses with rotary or linear motion.

Flange bearings are also much easier to replace compared to press-fit rotary bearings.  Because people can unbolt and remove the housing.

Materials of Bearings

A bearing seat is a precision grinding surface perpendicular to the axis of the bearing. It comes with two, three, or four mounting holes. Flanged bearings can be diamond, triangle, or square. With so many different variations, it is understandable that flanged bearings have a wide selection of materials.

The most common are cast iron, lightweight die-cast zinc, pressed steel, plastic, nylon, PTFE (polytetrafluoroethylene), acetal polymers, and stainless steel. Each unit has a spring-lid oil cap as well as rubber grommets to reduce noise and vibration.

Flange Bearings Applications

This kind of bearings are used in several different industries but are commonly seen in lighter-duty applications such as automated conveyors, belt drives, machine construction, food industry, medical processing, and some agricultural machines. Their ability to handle heavy loads and resistance to water and chemicals makes them ideal for food industry processes, despite their limited temperature ranges.

Bearings with flanges are durable and versatile units that can be beneficial for many different applications. If you’re in the market, make sure you choose the correct bearing type for your particular application, to avoid unnecessary wear and tear.
