    • 4 Bolt Flange Bearing Units

    At Bearings Direct we are proud to offer a variety of 4 bolt flange bearing units.  4 bolt flange bearings are mounted within a flanged bearing housing and are preferred when the bearing mounting surface is perpendicular to shaft access.  4 bolt flanged ball bearing units have a square shape with four holes for mounting.  The four hole design accommodates higher loads than a two or three bolt flange.  For more information about 4 bolt flange bearing units, contact us today!
