Flange bearings require a special housing called a bearing flange housing. The housing is often affixed to a wall or other support structure and composed of cast iron or steel. Bolts that are threaded through the housing and into the flanged bearing secure the bearing in place inside the housing. The flange bearing is supported by and held in place by the flange bearing housing. The bearing’s housing also serves to shield it from dirt and other debris that may wreak havoc on the bearing’s internals. As a bearing gets hot, the housing can help get rid of that excess heat. When a flanged bearing is required, the flange bearing housing is an integral part of the design. The bearing’s flanged design requires special support, which is provided by the housing. The flange bearing housing does its part to keep the bearing cool by releasing excess heat from the bearing’s internals. Contact Totalbearing for flange bearing housing catalogue.




Machines of all stripes rely heavily on flange bearing housings. They make it simple to install bearings in a housing that can subsequently be fastened to the chassis of a machine or any other type of support structure. There is a wide range of flange bearing housing types and sizes to choose from.

Pillow block and cartridge bearing housings are the two most common varieties of flange bearing housings. The most popular housing design is the pillow block, which is used for bearings with a shaft diameter of up to four inches. For bigger bearings, cartridge housings are a good option, and they may be tailored to your needs.

Cast iron or steel is commonly used for flange bearing housings. Plastic and composite materials are also used in the manufacturing of some enclosures. The housing’s needed strength and stiffness, as well as the working environment, will often dictate the material choice.

To ensure a smooth operation of the bearings they house, flange bearing housings must be precisely manufactured. When bearings are housed in housings that are either too big or too tiny, the former can produce noise while the latter can cause them to bind and overheat, leading to an early failure of the bearings. The application and operating circumstances must be taken into account when choosing a flange bearing housing. The shaft diameter, housing strength and stiffness, operating temperature, and bearing life span are all important variables to think about.

Advantage of the Product

Supporting a spinning shaft is the job of a flange bearing. Bearings are housed in a disk that serves as the flange and is attached to the shaft. Supporting and preventing the shaft from wiggles and jiggles, bearings are often constructed of steel.

Using a flange bearing has many benefits. In the first place, it makes for a more tranquil and vibration-free rotation of the shaft. Because of this, the shaft and bearings may last longer than expected. Second, if a flange bearing ever wears out or gets damaged, it’s simple to replace it. Lastly, flange bearings have several uses, including those requiring high speeds.


The bearings are held securely in place and shielded from debris and other potential hazards by the Flange Bearing Housing. Many varieties of flange bearing housings are available, each with its own special characteristics. Flange bearing housings often have the following characteristics:

  • A flange is a plate that fits onto the bearing housing. This flange has two purposes: it secures the bearings in place and shields them from dirt and other debris that might cause harm.
  • Standard flanges are the most common, however expanded flanges are also common. Smaller bearings normally utilize standard flanges, whereas bigger bearings require extended flanges.
  • The bearings of a flange bearing are held in place by the housing. The housing is usually square or rectangular and composed of steel or aluminum.
  • Steel or ceramic is commonly used for the bearings. Although steel bearings tend to last longer, ceramic bearings may actually function better in specific situations.
  • Seals are included with many flange bearing housings. These seals prevent unwanted particles like dirt and debris from entering the bearings and can even aid in keeping the bearings oiled.

FAQs of the product

A flange bearing housing is defined.

In order to properly support a bearing, a flange bearing housing is typically employed. The bearing is supported and held in place by a flange that projects from the side of the housing. As an added bonus, the flange prevents the bearing from shifting excessively and disrupting machine operation.

Can you explain why a flange bearing housing is advantageous?

Using a flange bearing housing has many advantages. The primary advantage is that the flange provides additional bearing support and stability. The flange’s second advantage is that it aids in limiting the bearing’s motion, which would otherwise interfere with the machine’s performance. Thirdly, the flange may be used to seal the housing, which helps to retain the lubricant within the housing and keeps it clean.

Which flange bearing housing varieties exist?

Bearing housings with flanges can be found in a number of variations. The two-bolt flange housing is by far the most prevalent form of flange bearing housing. The bearing in this housing is held in place by two bolts that protrude from the housing’s side. Flange bearing housings can also take the form of the four-bolt flange housing. The bearing in this style of housing is supported by four bolts that protrude from the side of the housing. The final variant of flange bearing housing is the six-bolt variety. This housing style is distinguished by the six bolts that protrude from the housing’s sides and hold the bearing in place.

Flange bearing housings are installed in what way?
