KFL08 8mm Pillow Block Flange Bearing Diameter

The insert bearings are the deep groove ball bearings with wide inner rings. Pillow Block Flange Bearing is widely used in various types of machinery, such as machinery and equipment, conveyors, machine manufacturing, etc.

Great alignment support for the screw as it turns to keep your print head or cutter in perfect alignment while moving. What makes these special is you can lock the T8 screw in place while the bearing lets it spin. They can align easily during operation and can be conveniently mounted or dismounted.

The bearing unit is supplied with fully sealed inserts fitted in the oval cast aluminum housing. The bearing inserts that self-align in the housing have 2 grub screws to allow tightening of the shaft once fitted. As required, the supplied insert can be removed from the housings for future replacement.

Applications:

These units are very versatile and can be used in a wide variety of applications. It can range from shafts supported by single to several bearings units. For example:

• Popularly used to support the ends of linear motion assemblies
• Flanged bearings are most commonly used in light-duty applications requiring linear motion or shaft end support
• Used in the mechanism of food processing machinery, conveyors, material handling, belt drives in HVAC, textile machines, baggage systems, medical processing and various other light-duty industrial applications
• Also used in CNC, 3D Printers, Laser Cutting and Plotting Machines in linear assemblies
• Belt drives connecting motors and pumps
• Long shafts connecting motors and industrial gearboxes
• Conveyor belt roller
• Rolling mills
• Ventilation systems
• Paper machines

Why are these types of bearings needed?

Flanged bearings are most commonly used when the application requires the bearing to be locked in place. The design engineer will want to lock the bearing axially, along the shaft, perpendicular to the shaft, or radially, depending on his application. A flanged bearing is used in this instance to help withstand axial thrusting. If there is any axial load or axial push on the bearing, the flange will prevent the bearing from moving axially.

What applications benefit from these types of ball bearings?

Any application that will require a bearing to be mounted in a high-vibration area, as well as any application that requires high axial loads, will benefit from using a flanged bearing.  Automotive applications are a good example; all vehicle components must be able to withstand high vibrations. The design engineer needs to be able to select and assemble a bearing that will withstand vibrations, as well as high temperatures. Therefore, adhesive or interference fit in the assembly of a bearing into an automotive application is often insufficient. To insure the long life and durability of the bearing, the selection comes down to a flanged bearing. A flanged bearing will maintain its position and will survive the hostile environment and vibration within the vehicle. If necessary, the assembly of a flanged bearing can also include a secondary attachment, like a retaining clip.

Very high temperatures will also require the selection of a flanged bearing.  Under the hood applications, where temperatures are often around 180°C and the presence of materials such as those between a ball bearing and a housing or shaft, it will create a different rate of thermal expansion.

For example, a steel bearing is pressed into aluminum housing; the housing may expand earlier than the steel bearing thus losing the interference with the bearing.  The use of a flanged bearing in this application will hold the bearing in place axially – regardless of the imbalance in the expansion rate.
