Browning 765660 2-bolt Flange Bearing Air Handling

Product Description

The BROWNING 765660 is a 2-bolt flange bearing designed for air handling applications. It accepts a 1-3/16 inch shaft and secures in place with a set screw lock. The bearing insert is manufactured from 52100 steel and housed in cast iron, delivering durability in demanding HVAC and air handling system environments. With a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds, this unit is built for sustained mechanical loads. Measured at 5-9/16 inches overall length and 3-1/8 inches overall height, it installs with a 7/16 inch bolt size. Licensed HVAC mechanics and millwrights are the typical installers on equipment where this bearing services fan shafts and blower assemblies.

This bearing is suited for use in air handling units, commercial and industrial blower assemblies, and fan shaft applications where a standard 2-bolt flange mount is required. The 4-19/32 inch distance between mounting hole centers matches common bolt patterns found in AHU fan decks and similar equipment. Its cast iron construction holds up in environments with moderate vibration and continuous duty cycles typical of commercial air handling systems.

Installation Notes

Installation is typically performed by licensed HVAC technicians or millwrights. De-energize and lock out the equipment before removing the existing bearing or installing this unit. Ensure the mounting surface is clean and flat before torquing the flange bolts, and verify set screws are tightened against the shaft per standard mechanical fastening practice. Consult applicable OSHA lockout/tagout procedures and local mechanical codes before beginning any bearing replacement work.
