Browning 730034 Type E 4-bolt Flange Bearing 3-7/16 in Bore

Product Description

The BROWNING 730034 is a Type E 4-bolt flange bearing designed to support mounted tapered roller bearing applications in industrial and mechanical drive systems. With a maximum bore diameter of 3-7/16 inches and an overall length of 9-1/4 inches, this unit is built for heavy-load shaft mounting where secure, multi-point flange attachment is required. The cast iron housing provides durability in demanding operating environments. Installation is typically performed by millwrights, maintenance mechanics, or industrial equipment technicians working on conveyors, fans, pumps, and similar rotating equipment.

This flange bearing is suited for use in industrial facilities, manufacturing plants, and commercial mechanical systems where large-bore tapered roller bearing mounts are specified. The 4-bolt mounting pattern with 3/4-inch bolt holes and a 7-inch distance between mounting hole centers makes it a direct fit for standard Type E flange configurations. The 5-1/4-inch width accommodates the tapered roller bearing assembly within the housing. Applications commonly include heavy conveyor drives, aggregate handling equipment, and industrial blower shafts.

Installation Notes

Installation should be performed by qualified millwrights or maintenance mechanics. De-energize and lock out all associated drive equipment before mounting or removing bearing units per OSHA lockout/tagout procedures. Ensure mounting surfaces are flat and clean before torquing fasteners, and verify shaft alignment after securing the flange to prevent premature bearing wear. Do not apply force directly to the bearing rollers or housing during installation.
