Mounted block bearings, also known as housed bearings, are a type of rolling-element bearing that are commonly used in industrial applications. These bearings are mounted inside a housing that is attached to a shaft or other mechanical component, allowing for smooth and efficient operation. In this blog post, we will provide an overview of the different kinds of mounted block bearings, their construction, and their applications.
- Pillow Block Bearings: Pillow block bearings are the most commonly used type of mounted block bearing. They are designed to be mounted on a flat surface and consist of a cast-iron or pressed steel housing with a spherical outer diameter. The bearing insert is typically a deep-groove ball bearing or a spherical roller bearing, and is secured to the shaft using set screws or an eccentric locking collar. Pillow block bearings are commonly used in conveyor systems, HVAC systems, and agricultural equipment.
- Flange Block Bearings: Flange block bearings, also known as flange mounted bearings, are designed to be mounted on a perpendicular surface. They consist of a housing with a flat face and four mounting holes, and the bearing insert is typically a ball bearing or a spherical roller bearing. Flange block bearings are commonly used in conveyor systems, printing presses, and food processing equipment.
- Take-Up Bearings: Take-up bearings, also known as frame mounted bearings, are used to provide tension and support for conveyor belts and other types of linear motion systems. They consist of a bearing insert and a cast-iron or pressed steel housing with an adjustable slot or set screw that allows for easy adjustment of the bearing position. Take-up bearings are commonly used in the mining, construction, and manufacturing industries.
- Cartridge Bearings: Cartridge bearings are a type of mounted block bearing that consist of a bearing insert and a one-piece housing that is factory-sealed and pre-lubricated. They are designed to be easily replaceable, and can be used in a wide range of applications, including conveyor systems, packaging equipment, and material handling systems.
- Hanger Bearings: Hanger bearings are used to support rotating shafts in situations where the shaft is suspended from an overhead structure. They consist of a bearing insert and a cast-iron or pressed steel housing with a hanger bracket that is attached to the overhead structure. Hanger bearings are commonly used in conveyor systems, overhead cranes, and hoists.
In conclusion, there are several different kinds of mounted block bearings, each with their own unique features and applications. Choosing the right type of mounted block bearing for your application is essential to ensure optimal performance and longevity. Whether you need a pillow block bearing for your HVAC system or a take-up bearing for your mining equipment, there is a mounted block bearing available that will meet your needs.
