What are the different types of flange bearings and what are they used for?


Flange ball bearings which are mounted in cast iron housing, thermoplastic and stainless steel, are used in conjunction with various other bearing types. The flange design is intended to help with the operating, mount and position of miniature bearings, other types of bearings, and instruments. Flange bearings can reduce issues such as axial overload, shaft flexing and vibrating problems.


Flange bearings are frequently supportive of ball, roller and needle roller bearings. They're also used with plain bearings as well. Here's the different versions:


2 Bolt Flange Bearings: Usually incorporates a wing or diamond shape. The holes for mounting the bearing maintain a straight axial line that runs directly through the bearing axis. It's uses are mostly to lend mechanical equipment support to intermediate shaft speeds and load sizes that use a mounting surface and shaft that are perpendicular.


3 Bolt Flange Bearings: The most common design is a circular flange mount with three mounting holes that are spaced equally. There are other variations that use offset mounting holes depending on the application. This version also uses bearings that can be aligned and moved for accommodating longer shafts. Their uses are intended for light to medium loads within the auto, agriculture, conveyor and industrial fields.


4 Bolt Flange Bearings: This design 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.


Which flange bearing types you need mostly depends on what you need it for. Contact us for a quote if some of the flange ball bearing you need.
