Browning 765805 2-bolt Flange Bearing 1-7/16 in Id

Product Description

The BROWNING 765805 is a VF2S-223 AH series 2-bolt flange bearing designed for air handling applications. It accepts a 1-7/16 inch shaft bore and features a set screw lock for secure shaft retention. The cast iron housing provides durability in industrial and commercial air handling environments. Static load capacity is rated at 3,493 pounds, and dynamic load capacity reaches 5,782 pounds, making it suitable for demanding continuous-duty installations. The ball bearing insert is manufactured from 52100 steel. Maximum operating speed is 4,000 RPM. This unit is installed by millwrights, HVAC mechanics, and maintenance technicians working on fan shafts and blower assemblies.

The BROWNING 765805 is intended for air handling unit (AHU) installations in both commercial and industrial settings. Typical applications include belt-driven blower shafts, fan bearing replacements, and new-construction fan assemblies where a 2-bolt flange mount is specified. The VF2S 200 series is commonly found in rooftop units, makeup air handlers, and industrial ventilation systems. Mounting hole centers are spaced 5-1/8 inches apart, accommodating standard 1/2 inch mounting bolts.

Installation Notes

Installation is typically performed by a licensed HVAC mechanic or industrial millwright. Disconnect and lock out all power to the fan or blower assembly before removing or installing the bearing. Ensure the shaft is clean and free of burrs before seating the bearing; tighten set screws to the fastener manufacturer specification using an appropriate hex key. Lubricate the bearing per the equipment OEM schedule before returning the unit to service.
