Browning 767417 4-bolt Flange Bearing 1-11/16 in Bore

Product Description

The BROWNING 767417 is a VF4S-227 series 4-bolt flange bearing unit designed for shaft support and radial load transfer in industrial rotating equipment. It features a 1-11/16 inch bore with a set screw lock style insert, making it suitable for fixed-shaft mounting applications where precise positional control is required. The cast iron housing provides durability in moderate industrial environments. With a static load capacity of 5,139 pounds and a dynamic load capacity of 7,901 pounds, this unit handles significant radial loads. Licensed HVAC and mechanical technicians, millwrights, and industrial maintenance technicians commonly install this bearing in fan assemblies, conveyor drives, and similar rotating machinery.

The BROWNING 767417 is suited for use in industrial and commercial applications involving belt-driven or direct-coupled rotating shafts. It is commonly found in blower assemblies, material handling equipment, and light industrial machinery where a secure 4-bolt flange mount is required. The 4-bolt mounting pattern with 4-1/8 inch center-to-center spacing allows for rigid, stable installation on equipment frames and mounting plates. Maximum operating speed is rated at 3,000 RPM. Lubrication is required during installation and as part of ongoing maintenance intervals.

Key Features

• 1-11/16 inch bore accommodates standard shaft diameters in industrial blower and conveyor applications
• Set screw lock type insert provides positive shaft retention without a locking collar
• 52100 steel bearing insert offers high hardness and fatigue resistance under cyclic loading
• Cast iron housing withstands mechanical shock and moderate environmental exposure
• 5,139 pound static and 7,901 pound dynamic load ratings support demanding radial load applications
• 4-bolt flange pattern with 4-1/8 inch mounting hole centers for stable, rigid installation

Compatibility

Designed as an OEM-style replacement or direct-installation 4-bolt flange bearing unit for industrial rotating equipment requiring a 1-11/16 inch bore, 4-bolt flange mount, and set screw shaft lock in the VF4S 200 series configuration.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician familiar with bearing mounting practices. Power down and lock out all energy sources to the driven equipment before handling. Apply grease to the bearing insert before mounting, and ensure the shaft is clean and free of burrs before pressing or sliding the bore onto the shaft. Torque all four mounting bolts evenly in a cross pattern to secure the housing without distorting the flange.
