What Is Bearing Housing?

 


Where there is a bearing, there will always be a bearing housing. It is as important in rotating machinery as the bearing itself. It plays a huge role in large and extra large equipment.

While the bearing supports rotating shafts and reduces friction, the housing that holds them ensures proper alignment and support for bearings. It also handles composite loads like radial and axial forces and maintains optimal performance under varied stresses.

In this blog, we primarily look at the significance of a bearing housing and its types.

Why Is Bearing Housing Important?

No bearing housing would mean inviting damage to the bearing.

After all, the housing protects bearings from contaminants like dust and moisture. It prevents bearing misalignment and keeps it safe from mechanical damage.

Moreover, it also reduces vibration for smoother operation. As a result, it significantly reduces maintenance costs, downtime, and extends the service life of bearings.

So, where can one see bearing housings more commonly? They can be seen in machines with rotating parts like motors, fans, conveyors, and pumps where they help reduce friction and wear between moving components.

Types of Bearing Housing

Bearing housings come in different types depending on applications and conditions.

  • Pillow Block Housing: This one is the most widely used housing type. Its bottom has mounting holes, which make installation easier. It is mounted on a surface and is  commonly used in general industrial machinery.
  • Split Housing: The design of split housing has two halves, making assembly and maintenance smoother, especially in large machinery.
  • Flanged Housing: This particular type comes with a flat or round flange that allows mounting on walls or frames.
  • Take Up Housing: It is commonly found in conveyor systems where the bearing position needs to be adjusted.

The selection of a housing type depends on factors like space, load direction, speed, and environmental conditions.

Thermoplastic Bearing Housings

In recent years, various industries have been opting for thermoplastic bearing housings.

Thermoplastic housings use high quality plastic materials. Contrary to traditional metal material, thermoplastic is lighter and eliminates extra weight from equipment. To enhance thermoplastic housing’s strength, some manufacturers mix stainless steel with the material.

Additionally, it offers impressive corrosion resistance. It is easy to clean and comes with a long service life. And it does not require maintenance all the time.

With these many benefits, industries like pharmaceuticals, food processing, and chemical manufacturing prefer thermoplastic bearing housings over traditional metal ones.

When it comes to choosing between thermoplastic and metal housings, the decision should be made after considering factors like operating environment, load requirements, and cost; since these factors affect their suitability for specific applications.

Conclusion

In short, a bearing housing with robust design is essential for reliable machinery operation. It provides protection, alignment and support for bearings across various applications.

The Role of Bearings in the Aviation Industry

Image
  Though small in size, bearings are the backbone of many industries that involve rotary machines and equipment. The aviation industry is no exception. However, this industry demands bearings that can handle extreme heat and immense pressures. They should be able to operate efficiently in corrosive environments. In this blog, we look at a few important applications of bearings in this aviation industry. Key Applications of Bearings in Aviation Bearings offer frictionless, smooth rotational, and linear motion between moving parts in the aviation sector. Commonly, in aircraft components, they are used in engines, flight control systems, and auxiliary power units. Flight Control Bearings Control bearings are specially designed to ensure smooth and responsive aircraft maneuvering. But how do these bearings help? Basically, they minimize friction and enable precise movement of control surfaces like ailerons, elevators, and rudders. For example, flight control linkages rely on spherical ...

Types of Main Bearings Used in Marine Industry

Image
  Lead Bronze, Bi-Metal, and Tri-Metal bearings: These three types of bearings play a huge role in the marine industry. They are utilised to support rotating shafts and reduce friction to ensure smooth rotations. These bearings come with distinct benefits such as high load-bearing capacity, wear and corrosion resistance. Let us explore what these three bearings are made of, how many layers they have, and what they are used for. Lead Bronze Bearing Flash layer: This topmost layer is composed of tin and lead. It is 0.035mm thick. This layer’s job is to protect the bearing from getting corroded and dust when not being used. It flashes off when a bearing is running. Nickle Barrier: This 0.02mm thick layer - made of nickel - helps prevent corrosion and avoid diffusion of tin into bearing metal. Lead Bronze: The third layer comes with an anti-seizing property. It is made of lead bronze. This layer is great at preventing parts from sticking together. In the setup, it is the main part th...
