Standard Flanged Ball Bearings

Standard flanged ball bearings feature an integrated flange that simplifies mounting and ensures precise alignment in various applications. These bearings are widely used in conveyor systems, robotics, and small-scale machinery.

The Accuracy of Flange Ball Bearings

It’s crucial to differentiate a standalone flange ball bearing component from a complete mounted housing bearing unit. While the former is the bearing itself (a ball bearing with flange), terms like flange block bearing, pillow block flange bearing, or flange pillow block typically describe an assembly where a bearing insert is pre-installed into a separate flanged housing.

TFL provides both the individual flanged ball bearings and these complete housed unit solutions.

Common Mounting Configurations: 2 Bolt and 4 Bolt Flange Bearings

Flanged ball bearings are available in several mounting styles to suit different load and stability requirements.

The most prevalent are the 2 bolt flange bearing (also known as a two bolt flange bearing) and the 4 bolt flange bearing (or four bolt flange bearing). These designations refer to the number of bolt holes integrated into the flange itself, allowing direct attachment to a machine frame or panel.

Generally, the 4 bolt flange configuration offers enhanced stability and load distribution compared to the two-bolt version.

Applications and Sizing for Flange Ball Bearings

The ease of mounting makes flange ball bearings ideal for applications across various industries, including conveyor systems, automation, packaging machinery, and light-duty power transmission where precise shaft location is needed without complex housing designs.

TFL offers these versatile bearings in a wide array of standard inch and metric sizes, including common requirements like the 1 inch bearing with flange (or 1 flange bearing), ensuring you can find the right fit for your specific shaft diameter and load needs.

FREQUENTLY ASKED QUESTIONS

Are flange block bearing units built for high speeds?

Yes, our flange block bearing designs ensure smooth, high-speed operation for industrial applications.

When should I choose a 4 bolt flange bearing over a 2 bolt one?

Choose a 4 bolt flange bearing when you need greater mounting stability, higher load capacity, or better distribution of forces. The 2 bolt flange bearing is suitable for lighter loads or applications where space for mounting hardware is more limited.

Is a "flange block bearing" just another name for a flanged ball bearing?

No, they are different. A flanged ball bearing is the individual bearing component with an integrated flange. A flange block bearing is a type of mounted housing bearing unit – it consists of a bearing insert (which could be various types, including standard or flanged) inside a separate housing that has a flanged base for mounting.

Are flanged ball bearings available in specific inch sizes like 1 inch?

Absolutely. Flanged ball bearings are manufactured to standard inch and metric dimensions. A 1 inch bearing with flange is a common size readily available from suppliers like TFL, along with many other dimensions to fit various shafts.
