Flange Block Bearings

Flange mounted bearings are used when the shaft axis is perpendicular to the bearing mounting surface.  They incorprate a sealed bearing that is preassembled into a flanged housing.  The housing contains a precision ground surface perpendicular to the bearing axis and two, three or four mounting holes, depending on the style.  The bearing can be unbolted and removed, which makes bearing replacement easier and faster than traditional rotary beairngs that must be press fit into a housing.  Flange mounted bearings can also support heavy loads, which protects the shaft from deflection, which could cause vibration or other damage.

The size of the bearing is important to consider when making a selection.

  • Shaft size specifies the maximum diameter of the shaft or the bore diameter of the bearing.

  • Height above mounting surface is important to take into consideration for low clearance applications.
