Q19. What are flanged ball bearings?

Many ball bearings have flanges as options to their configurations. The flange is designed to aid in mounting and positioning.  This is especially true for miniature and instrument bearings but applies to other ball bearing types.  To see various types of flanged ball bearings (non-mounted), please visit the links below:

Flanges are also used with bearings on external housings used to mount a bearing unit. A mounted bearing unit acts as a system to position the bearing securely for reliable operation. To learn more about flanged mounted bearing units, please visit Pillow Blocks, Flanges, Take Up Units, and Bearing Inserts.
