Browning 730031 4-bolt Flange Bearing 2-15/16 in Bore

Product Description

The BROWNING 730031 is a Type E 4-bolt flange-mount bearing housing fitted with a tapered roller insert designed for heavy radial and thrust load applications in industrial and commercial equipment. The housing is cast iron with a maximum bore diameter of 2-15/16 inches and an overall length of 7-3/4 inches. The bearing secures to the shaft via a set screw lock and requires periodic lubrication to maintain service life. Maximum operating speed is 1500 RPM. This unit is a direct-mount solution for rotating shaft assemblies where rigid, bolt-down support is required on machinery frames, conveyor systems, or process equipment.

The 730031 is suited for heavy-duty industrial installations where a tapered roller insert is needed to handle combined radial and axial loads. The 4-bolt flange pattern with 6-inch center-to-center bolt hole spacing allows secure mounting to flat structural surfaces. The 3/4-inch bolt size and cast iron housing construction make this bearing appropriate for demanding environments including agricultural equipment, manufacturing lines, and material handling systems. Installation is typically performed by millwrights or industrial maintenance technicians.

Installation Notes

Installation should be performed by a qualified millwright or industrial maintenance technician. Disconnect and lock out all power to the machine before mounting or servicing the bearing. Ensure the mounting surface is flat and clean before torquing flange bolts, and verify shaft diameter is within the specified bore range before securing set screws. Lubrication is required at initial installation and at regular service intervals per equipment maintenance schedules.
