Sourcing the right mounted components is essential for optimizing machine performance, and our extensive catalog at 3BG Supply offers an unparalleled selection of high-quality flange bearings designed for severe industrial service. A mounted flange bearing (frequently designated as a flange bearing) features a specialized outer housing with a built-in flange that bolts directly perpendicular onto a machine framework or vertical wall support. This perpendicular mounting arrangement ensures uncompromising stability and exact shaft alignment, effectively neutralizing heavy radial and thrust forces. Depending on the mechanical load profiles of your conveyor lines, agricultural equipment, or industrial food processing machinery, you can choose from a robust 4 bolt flange bearing for maximized structural support or a space-saving 2 bolt flange bearing for compact footprints. Our premium inventory features both a classic cast iron flange bearing for everyday dampening capability and an advanced heavy duty flange bearing built to thrive amidst extreme vibration and debris.
3BG Supply Co. offers a broad selection of these helpful products. You can use our helpful search filters to narrow options to the exact width, height, diameter and other configurations you need.

Flange Mounted Bearings
You can use flange bearings to mount objects to perpendicular surfaces. These tools have a cylindrical body with a flange, which is a protruding flat surface that strengthens or maintains an object's position, on one end. The flange makes it easier to mount the bearing during installation, as it locks the bearing into place to prevent it from moving or becoming loose.
All flange bearings are designed to support heavy loads and resist contamination and rust. Many different flange bearings exist, each with specifications for particular applications, and they're commonly used in situations with many vibrations. Flange bearings are often found in:
- Industrial Machinery: All moving parts of machines require bearings to move properly. Flange bearings allow various components to attach to cars and hold them in place.
- Food processing machinery: Flange bearings can also benefit the many components and machines used to prepare or store food products.
- Conveyor belts: These bearings hold inner bushings in place while conveyor belts move, letting them function correctly.
3BG Supply Co. offers flange bearings in a wide range of sturdy materials, including:
- Stainless steel
- Nylon
- Thermoplastic
In addition, we offer different configurations for your needs, such as:
- 2-bolt flange bearing
- 3-bolt flange bearing
- 4-bolt flange beating

FAQs
What is a flange bearing and how does its mounting configuration differ from a pillow block?
A flange bearing consists of an insert bearing pre-installed within a specialized flanged housing designed to mount flush against flat surfaces. The core difference between flange bearings and pillow blocks lies in the orientation of the mounting surface relative to the rotating shaft. A pillow block positions a shaft parallel to its mounting base plate, whereas a mounted flange bearing secures a shaft perpendicular to the mounting frame or bulkhead. This makes flanged configurations the ideal choice for wall pass-through points, structural side frames, and vertical elevator drives.
When should I implement a 4 bolt flange bearing versus a 2 bolt flange bearing?
The decision between a 4 bolt flange bearing vs a 2 bolt flange bearing depends on structural space constraints and applied mechanical loads. A 4 bolt flange bearing features a square or round housing geometry with four mounting holes, providing uniform force distribution and maximum stability under severe radial, shock, or combination loads. Alternatively, a 2 bolt flange bearing features a diamond-shaped housing footprint with just two opposing bolt holes. This diamond layout requires significantly less mounting real estate and simplifies installation, making it highly effective for light to medium-duty applications where structural space is strictly limited.
What environments benefit most from upgrading to a heavy duty flange bearing?
While a standard cast iron flange bearing is excellent for general MRO installations, you should upgrade to a heavy duty flange bearing when dealing with punishing industries such as mining, recycling, forest product processing, and heavy aggregate sorting. Heavy-duty housings are cast from thick-walled ductile iron or premium cast steel rather than standard gray iron, enabling them to resist cracking under intense structural stress. Furthermore, these heavy-duty assemblies incorporate advanced multilayered sealing mechanisms, like taconite or triple-lip contact seals, to completely block grinding dust, abrasive particulate, and water washdowns from destroying the internal rolling elements.
How can I maintain and relubricate a mounted flange bearing to maximize its service life?
To maximize the service life of your mounted flange bearing, establish a strict relubrication schedule using high-grade grease suited for your application's speed and temperature. Most industrial flanged housings include an integrated grease zerk that channels lubricant directly to the outer ring's lubrication groove. Pump grease slowly while the shaft is rotating to distribute it uniformly across the raceways, allowing old grease to purge out safely. Over-greasing can burst the internal bearing seals, so monitor grease volume carefully.
Can standard flange bearings handle heavy axial thrust loads?
While a standard cast iron flange bearing is primarily optimized to support radial loads (forces acting perpendicular to the shaft), the internal ball or roller bearing inserts can accommodate moderate axial thrust loads (forces acting parallel to the shaft) in both directions. However, if your application involves high-thrust continuous loads—such as vertical screw conveyors or heavy mixing blades—it is best to upgrade to a heavy duty flange bearing equipped with spherical or tapered roller bearing inserts, which are structurally rated for multi-directional load strains.
Should I choose a set-screw lock or an eccentric collar for a 2 bolt flange bearing?
For a standard 2 bolt flange bearing or 4 bolt flange bearing, set-screw locking is the most popular choice for uniform, bi-directional shaft rotation because it is simple to install and holds well on standard shafting. An eccentric locking collar is highly recommended for unidirectional rotation where heavy shock loads are present, as the collar naturally tightens itself against the shaft during operation. However, running an eccentric collar in reverse will loosen it. For highly critical or high-speed systems, a concentric adapter sleeve lock provides the most secure 360-degree grip to eliminate shaft marring and vibration.
