There are 3 main types of mounted units: pillow block, flange block, and hanger bearings. These units are used to support and stabilize the external rotating shaft. They can be in solid or split housing and come in tapered or cylindrical bore designs. They are self-aligning and are available in standard-duty and heavy-duty styles.
The Pillow Block Mounted Bearing is a type of mounted bearing that uses mounting holes perpendicular to the shaft. These bearings are commonly used in industrial applications. This type of mounted bearing can handle a variety of dynamic load ratings and lubrication requirements. They can be constructed of cast iron, pressed steel, or aluminum. While these are a common choice for many businesses in the construction, timber, aggregate, mining, and cement industries, they are also useful for large-scale, stationary manufacturing and processing applications.
A Flange Block Mounted Bearing is a type of mounted bearing that uses a flanged housing with a ball bearing insert. These are available in 2, 3, and 4-hole configurations. The housing protects the bearing and provides a mechanism for the bearing to be secured while it’s in use. It also helps prevent contaminants from entering the bearing. These types of bearings are commonly used in light-duty industrial applications, such as conveyors, material handling, and HVAC systems. They’re also popular in light-duty food processing machinery, textile machines, and baggage systems.
The Hanger Bearing Mounted Bearing is a type of mounted bearing that mounts to the shaft of an industrial screw-conveyor assembly. It is also used in automotive, aircraft, and marine drive shaft assemblies. The hanger bearing is an ideal choice for screw conveyors that convey abrasive bulk materials such as grains and wood fibers. Unlike ball-bearing mounted hanger bearings, this type of mounted bearing is more flexible to accommodate airframe deflections and assembly variations. Additionally, this type of bearing can reduce unequal operating angles between universal joints, thereby reducing vibration and stress.
