Browning 765626 2-bolt Flange Bearing 1 Inch Id Air Handling

Product Description

The BROWNING 765626 is a 2-bolt flange bearing unit in the VF2S 200 series, designed for air handling applications in HVAC and mechanical systems. It features a 1-inch inside diameter bore with a set screw lock and is housed in cast iron for durability under continuous load. The bearing insert is made from 52100 steel and is rated for a static load capacity of 1,651 pounds and a dynamic load capacity of 2,801 pounds. With a maximum operating speed of 5,500 RPM, this unit suits demanding fan shaft and blower applications. Lubrication is required during installation and as part of routine maintenance. HVAC mechanics and industrial maintenance technicians are the typical installers.

This flange bearing is suited for residential and commercial air handling units, blower assemblies, and fan shaft support applications where a compact 2-bolt mounting footprint is needed. The cast iron housing provides rigid support in both horizontal and vertical mounting orientations. The set screw lock design allows secure shaft engagement on 1-inch diameter shafts. With an overall length of 4-7/8 inches and an overall height of 2-3/4 inches, the unit fits within the space constraints common to AHU and fan coil installations. Mounting hole centers are spaced 3-57/64 inches apart, using 7/16-inch hardware.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical maintenance professional. Disconnect and lock out all power to the air handling unit before removing or installing the bearing. Ensure the shaft is clean and free of burrs before seating the bore and tightening the set screws. Apply appropriate grease at installation and follow the equipment manufacturer's recommended lubrication intervals for ongoing service.
