Flange mounts have bearings that are mounted inside of a flanged housing, and provide both the flange and the bearing in a single unit. These mounts are used when the mounting surface is perpendicular to the axis of the shaft, and have a round shape with three mounting holes.

Emerson Bearing provides 2-bolt flange mounts with set screws or eccentric locking collars. Options include Thermoplastic, cast iron, stainless steel, and nickel plating for the housing and collar. Each of these materialsmore
