What Is A Pillow Block Bearing Used For？
Pillow block bearing is a type of bearing that is used to support a rotating shaft. They are typically used in applications where the shaft is subjected to high loads or where there is a need for low friction. Pillow block bearing is available in a variety of sizes and styles to suit different applications.
Pillow Block Bearing Is Composed Of Two Main Parts:
- The inner race: This is the part of the bearing that contacts the shaft. It is typically made of a hard material, such as steel or bronze, and is machined to a precise tolerance.
- The outer race: This is the part of the bearing that contacts the housing. It is typically made of a softer material, such as bronze or nylon, to help absorb shock and vibration.
Between the inner and outer races is a layer of rolling elements. These elements can be made of a variety of materials, including steel, bronze, or nylon. The type of rolling element used will depend on the application.
Pillow block bearing is available in a variety of styles. The most common style is the single-row pillow block bearing. This type of bearing has a single row of rolling elements and is typically used in applications where the loads are light to moderate.
For applications where the loads are heavier, a double-row pillow block bearing can be used. This type of bearing has two rows of rolling elements and can support more weight than a single-row bearing.
Pillow block bearing can also be used in a variety of configurations. The most common configuration is the vertical configuration. In this configuration, the shaft is mounted vertically and the bearing is located at the bottom of the shaft.
For applications where the shaft is mounted horizontally, a horizontal pillow block bearing can be used. This type of bearing is typically used in applications where the shaft is subjected to high loads or where there is a need for low friction.
Pillow block bearing is a versatile type of bearing that can be used in a variety of applications. They are available in a variety of sizes, styles, and configurations to suit different needs.
Benefits Of Pillow Block Bearing
Pillow block bearing offer a number of benefits over other types of bearings, including:
- Low friction: Pillow block bearing has a low coefficient of friction, which means that they can operate efficiently even under heavy loads. This can save energy and reduce wear and tear on the bearing.
- High load capacity: Pillow block bearing can support high loads without sacrificing efficiency. This makes them ideal for applications where the shaft is subjected to heavy loads.
- Long life: Pillow block bearing is designed to last for many years, even under heavy loads. This makes them a good investment for applications where reliability is important.
- Easy to maintain: Pillow block bearing is relatively easy to maintain. They can be lubricated with a variety of different lubricants, and they can be replaced quickly and easily if necessary.
Applications For Pillow Block Bearing
Pillow block bearing are used in a wide variety of applications, including:
- Machine tools: Pillow block bearing is used in a variety of machine tools, such as lathes, mills, and grinders. They support the rotating shafts of these machines and help to ensure that they operate smoothly and efficiently.
- Industrial equipment: Pillow block bearing is used in a variety of industrial equipment, such as conveyors, pumps, and fans. They support the rotating shafts of these machines and help to ensure that they operate reliably and efficiently.
- Vehicles: Pillow block bearing is used in a variety of vehicles, such as cars, trucks, and buses. They support the rotating shafts of these vehicles and help to ensure that they operate smoothly and efficiently.
Pillow Block Bearing Vs. Other Types Of Bearings
Pillow block bearing is one of many different types of bearings that are available. Other types of bearings include:
- Ball bearings: Ball bearings are a type of rolling-element bearing that uses balls to support the rotating shaft. Ball bearings are typically used in applications where high speeds and low friction are required.
- Roller bearings: Roller bearings are a type of rolling-element bearing that uses rollers to support the rotating shaft. Roller bearings are typically used in applications where heavy loads and high shock loads are present.
- Sleeve bearings: Sleeve bearings are a type of plain-bearing that uses a sleeve to support the rotating shaft. Sleeve bearings are typically used in applications where low loads and low speeds are present.
Conclusion
Pillow block bearing is used to support rotating shafts in a variety of applications. They are typically made of cast iron or steel and have a cylindrical bore that fits snugly around the shaft. The bearing is then secured to the housing with bolts or nuts. Pillow block bearing can be used in both vertical and horizontal applications. In vertical applications, the bearings are typically mounted on the bottom of the housing. In horizontal applications, the bearings are typically mounted on the sides of the housing. Pillow block bearing is available in a variety of sizes and styles to meet the specific needs of each application.
Pillow block bearing is a versatile and reliable option for supporting rotating shafts. They are easy to install and maintain, and they can be used in a wide range of applications.
