How are flange mount bearings used for different applications?

2 Bolt Flange Bearing:

The holes for mounting the bearing maintain a straight axial line that runs directly through the bearing axis. The smaller, two-bolt designs are most commonly referred to as flangettes. Generally a wing or diamond shape, it is used to lend mechanical equipment support to intermediate load sizes and shaft speeds for mounting surface and shaft that are perpendicular.

3 Bolt Flange Bearings: 

It can be aligned and moved for accommodating longer shafts and intended for light to medium loads within the auto, conveyor, agriculture, and industrial fields. Though there are various other variations, the most common design is a circular flange mount with three mounting holes that are spaced equally.

4 Bolt Flange Bearings: 

This flange mount bearing typically is a housing that is square or round. The four hole mount pattern is radial around the axis of the bearing. They’re used frequently with a mounting surface perpendicular to the shaft, and handle rotating or linear movement. Four bolt designs feature a solid base with a wide inner ring for more heavy-duty applications.
