Types of mounted bearings

Mounted bearings, also known as bearing units or housed bearings, are complete assemblies that consist of a bearing and a housing. These assemblies are ready for installation and are designed to simplify the mounting process. Mounted bearings are commonly used in various industrial applications where ease of installation, maintenance, and space-saving are important factors. Here are some key features and types of mounted bearings:

1. Pillow Block Bearings:

  - Pillow block bearings are mounted in pillow-shaped housings and are typically used to provide support for a rotating shaft. The housing can be bolted to a support structure, and the bearing inside accommodates radial loads.

2. Flange Bearings:

  - Flange bearings have a flanged housing, allowing them to be easily attached to a surface. These bearings are suitable for applications where space is limited or axial positioning is crucial.

3. Take-Up Bearings:

  - Take-up bearings are designed to allow for the adjustment of the bearing's position to accommodate changes in tension in conveyor systems or other applications.

4. Cartridge Bearings:

  - Cartridge bearings are pre-assembled units that include both the bearing and the housing. They are designed for easy replacement and maintenance.

5. Hanger Bearings:

  - Hanger bearings are used to support a rotating shaft in applications such as conveyor systems. They are mounted from a beam or overhead structure.

6. Flange Cartridge Units:

  - Combine the features of flange bearings and cartridge bearings. They have a flanged housing and a pre-assembled cartridge bearing.

7. Two-Bolt and Four-Bolt Flange Units:

  - These units have housings with either two or four mounting bolts, providing stability and support. They are common in applications where precise mounting is required.

8. Round Flange Units:

  - Round flange units have a circular flange for easy mounting and positioning. They are often used in applications where a square flange might be less practical.

9. Eccentric Collar Locking Bearings:

  - Bearings with an eccentric collar that can be rotated to grip the shaft tightly, providing a secure locking mechanism.

10. Adapter Sleeve Bearings:

   - Bearings with an adapter sleeve that facilitates easy mounting and dismounting by adjusting the position of the bearing on the shaft.

Mounted bearings can incorporate various types of rolling elements, including ball bearings, roller bearings, or other specialty bearing types. The choice of mounted bearing depends on factors such as load requirements, speed, environmental conditions, and ease of maintenance. These bearings find applications in industries such as agriculture, mining, construction, and manufacturing, contributing to efficient and reliable machinery operation.
