Browning 767687 4-bolt Flange Bearing 1-15/16 in Id

Product Description

The BROWNING 767687 is a 4-bolt flange bearing unit in the VF4E 200 series, designed for industrial shaft support applications requiring a rigid, square-mount housing. It accepts a 1-15/16 inch bore shaft and seats a 52100 steel ball bearing insert secured by an eccentric lock collar. The cast iron housing delivers a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds. Rated to 3,000 RPM, this unit is suited for moderate-speed conveyor, fan, blower, and drive shaft installations. Licensed millwrights, maintenance mechanics, and industrial service technicians are the primary installers.

This flange bearing is used in light-to-medium industrial and commercial applications where a 4-bolt square-flange mount is required on a structural frame, bracket, or equipment panel. Typical installations include conveyor drive systems, agricultural equipment, industrial fans, and pump drive assemblies. The eccentric lock design allows field shaft alignment without requiring a setscrew on the shaft. The unit ships individually and requires periodic grease lubrication at the zerk fitting on the housing.

Key Features

• 1-15/16 inch bore accommodates standard fractional industrial shafting
• 52100 steel ball bearing insert for durability under radial and axial loads
• Cast iron housing resists deformation under high static loads up to 5,216 pounds
• Eccentric lock collar secures insert to shaft without machined grooves
• 4-bolt square flange pattern with 4-3/8 inch center-to-center bolt spacing and 9/16 inch bolt holes
• Grease-lubricated design supports field serviceability and extended service intervals

Compatibility

Designed as an OEM-style replacement or new-installation flange bearing for industrial equipment requiring a 4-bolt square-flange unit with a 1-15/16 inch bore in the VF4E 200 series form factor.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic with the drive system fully de-energized and locked out per OSHA lockout/tagout procedures before mounting. Align the shaft squarely through the bore before tightening the eccentric lock collar in the direction of shaft rotation. Torque all four flange bolts evenly to the equipment manufacturer's fastener specification for the 9/16 inch bolt size. Apply fresh grease to the fitting at initial installation and at regular intervals as required by the operating environment and RPM.
