Browning 730022 Type E 4-bolt Flange Bearing 1-1/2 in Bore

Product Description

The BROWNING 730022 is a Type E 4-bolt flange bearing with a mounted tapered roller design, built for industrial and commercial power-transmission applications. It accepts a maximum bore diameter of 1-1/2 inches and has an overall length of 5-3/8 inches, with mounting hole centers spaced 4-1/8 inches apart. The housing is cast iron, providing the rigidity and load capacity required in demanding shaft-support installations. This bearing is installed by millwrights, maintenance mechanics, and industrial service technicians working on rotating equipment in manufacturing, HVAC drive systems, conveyor lines, and similar machinery.

The 730022 suits applications where a rigid, flange-mounted tapered roller bearing is required to handle combined radial and axial loads. Its 4-bolt mounting pattern distributes clamp load evenly across the housing, making it appropriate for moderate to heavy-duty shaft support in both new installations and direct replacement service. The cast iron housing handles typical industrial environments and is compatible with standard 1/2-inch mounting hardware at each bolt position.

Key Features

• Type E 4-bolt flange configuration for stable, even mounting on flat surfaces
• Mounted tapered roller bearing supports combined radial and thrust loads
• 1-1/2 inch maximum bore diameter accommodates standard industrial shaft sizes
• 4-1/8 inch distance between mounting hole centers for consistent bolt pattern layout
• Cast iron housing provides rigidity and durability under continuous load
• 1/2-inch bolt size for compatibility with widely available fastener stock

Compatibility

Designed as an OEM-style replacement or new-installation flange bearing for industrial rotating equipment requiring a Type E 4-bolt mounted tapered roller bearing with a 1-1/2 inch bore and 5-3/8 inch overall length.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician familiar with shaft alignment and bearing seating procedures. Degrease the shaft and bore before installation and verify shaft diameter tolerance against the bearing bore specification. Torque all four mounting bolts evenly in a cross pattern using the fastener size and grade appropriate for the application per applicable machinery standards. Never apply impact force directly to the bearing races during installation or removal.
