Browning 730021 Type E 4-bolt Flange Bearing 1-7/16 Bore

Product Description

The BROWNING 730021 is a Type E 4-bolt flange bearing designed to mount tapered roller bearing assemblies in industrial and mechanical drive applications. With a maximum bore diameter of 1-7/16 inches and an overall length of 4-5/8 inches, this unit provides a rigid, bolt-down mounting solution for rotating shaft assemblies. The cast iron housing delivers durability under load and resists deformation in demanding service environments. Installation is handled by maintenance technicians and millwrights working on conveyor systems, blower assemblies, and similar equipment requiring reliable shaft support.

This bearing is suited for use in light-to-medium industrial applications where a 4-bolt flange mount is required for positive housing retention. The 3-1/2 inch distance between mounting hole centers and 1/2 inch bolt size allow straightforward alignment to standard bolt patterns on equipment frames and mounting plates. The tapered roller design accommodates combined radial and axial loads. Typical install scenarios include conveyor drive shafts, fan shaft assemblies, and general power transmission equipment in commercial and industrial facilities.

Key Features

• Type E 4-bolt flange configuration for positive, rigid shaft mounting
• Maximum bore diameter of 1-7/16 inches accommodates common shaft sizes
• Cast iron housing provides strength and resistance to deformation under load
• 3-1/2 inch center-to-center mounting hole spacing for standard bolt pattern alignment
• 1/2 inch bolt size for secure fastening to equipment frames
• Overall length of 4-5/8 inches with a width of 3-5/64 inches for compact envelope fit

Compatibility

Designed as an OEM-style replacement or direct-mount flange bearing for industrial shaft assemblies requiring a Type E 4-bolt flange configuration with a 1-7/16 inch bore.

Installation Notes

Installation is typically performed by a qualified millwright or maintenance technician. Shut down and lock out all power to the equipment before removing or installing the bearing assembly. Ensure the mounting surface is flat and clean, and verify shaft diameter and bolt pattern dimensions before mounting. Do not over-torque the mounting bolts; follow the equipment manufacturer fastener specifications for proper clamping force.
