Browning 767903 2-bolt Flange Bearing 1-15/16 in Id

Product Description

The BROWNING 767903 is a 2-bolt flange bearing unit from the VF2E 20 series, designed to support rotating shafts in industrial and commercial mechanical drive systems. It combines a cast iron housing with a 52100 steel ball bearing insert, secured to the shaft via an eccentric lock collar. The bore measures 1-15/16 inches in diameter, the overall length is 7-7/16 inches, and the overall height is 4-9/16 inches. Static load capacity is 5,216 pounds and dynamic load capacity is 7,889 pounds. This unit is installed by millwrights, maintenance technicians, and industrial mechanics in fan, conveyor, pump, and blower applications.

This flange bearing is suited for light to medium industrial duty applications where a two-bolt footprint is required for mounting to frames, panels, or structural members. The 6-3/16-inch center-to-center bolt spacing and 9/16-inch bolt size accommodate standard structural fasteners. With a maximum rated speed of 3,000 RPM, it fits moderate-speed rotating equipment. Lubrication is required during installation and at regular service intervals. Typical applications include HVAC fan shaft support, agricultural equipment, material handling systems, and general power transmission machinery.

Key Features

• Cast iron housing provides rigidity and resistance to deflection under load
• 52100 steel ball bearing insert rated for 5,216 lb static and 7,889 lb dynamic load capacity
• Eccentric lock collar secures the insert to the shaft without a set screw keyway
• 2-bolt mounting pattern with 6-3/16-inch hole center-to-center spacing
• Maximum operating speed of 3,000 RPM suits moderate-speed fan and conveyor shafts
• Grease fitting included — lubrication required for proper operation and service life

Compatibility

Designed as an OEM-style replacement or new-installation 2-bolt flange bearing for 1-15/16-inch diameter shafts in industrial and commercial rotating equipment. Compatible with standard 9/16-inch mounting hardware per the VF2E 20 series envelope dimensions.

Installation Notes

Installation is performed by qualified millwrights or mechanical maintenance technicians. De-energize and lock out all power to the drive system before removing or installing the bearing unit. Ensure the shaft is clean and free of burrs before seating the bore. Torque mounting bolts to the structural fastener specification for the mounting surface, and apply grease through the fitting before initial startup. Do not operate the unit without lubrication in place.
