Machines with exposed rotating shafts typically require mounted bearings. Mounted bearings are mechanical assemblies that have a bearing mounted inside a housing for convenience of installation and added support. Mounted bearings, also known as bearing units or bearing blocks, offer ways to support rotating shafts and reduce friction between the shafts and stationary machine parts. In applications where the shaft is perpendicular to the unit, mounted bearings are face or surface mounted. In an existing bearing housing, bearing inserts are utilised to replace worn or damaged bearings. At the ends of conveyors, mounted bearings serve as take-up units, while at intermediate points, they serve as flanged units. The bearing configurations can be rolling-element or journal bearing.
- • Have long service life.
- • Quick and easy to mount.
- • Reduced vibration and noise levels.
- • Accommodate any initial misalignment.
Examples of Types of Mounted Bearing
1. Pillow block bearings (Plummer block bearings)
Pillow block bearings, also known as plummer block bearings, are the most prevalent type of mounted bearing that have a housing and an insert bearing, which are usually self-aligning. Pillow block bearings are often designed for lighter loads and less rigorous applications. Typically, pillow blocks come with a bearing installed, and to make bearing replacement and disassembly simple, split housing designs by FEIKEN are also offered. Pillow block bearings can be used on inclined, horizontal, or vertical surfaces. They safely permit rotation of the inner ring while keeping the outer ring stationary.
2. Flanged bearings
Flanged bearings, a type of mounted bearing, usually mounted on vertical surfaces with the shaft making a right angle through the machine frame, are often used in light-duty applications. They are used for conveyors, baggage systems, food processing machinery, and several other light-duty industrial applications. This type of bearing consists of a cylindrical cartridge with a flange at one end for better mounting and support.
