Browning 766957 2-bolt Flange Bearing 1 Inch Id Cast Iron

Product Description

The BROWNING 766957 is a VF2B 200 Series 2-bolt flange bearing unit designed for industrial and mechanical drive applications. It combines a ball bearing insert made from 52100 steel with a cast iron housing, delivering a static load capacity of 1,651 pounds and a dynamic load capacity of 2,801 pounds. The bore measures 1 inch in diameter with an overall length of 4-7/8 inches and an overall height of 2-3/4 inches. A concentric collar lock secures the bearing insert to the shaft. Licensed HVAC, mechanical, and industrial technicians install this unit in belt-driven and shaft-driven equipment where secure, low-maintenance flange mounting is required.

The 766957 is suited for light-to-medium duty shaft support in residential and commercial mechanical systems, including HVAC fan assemblies, conveyor drives, blower shafts, and agricultural or industrial equipment. The 2-bolt mounting pattern simplifies installation on standard mounting plates and frames. With a maximum operating speed of 5,500 RPM and a base-to-center distance of 0.875 inches, this unit fits a wide range of standard shaft-driven configurations. Lubrication is required for proper operation and service life.

Installation Notes

Installation is typically performed by licensed mechanical or HVAC technicians. Shut down and lock out the drive system before removing or installing the bearing unit per applicable OSHA lockout/tagout procedures. Secure the housing bolts evenly using appropriately sized fasteners through the 7/16 inch bolt holes. This bearing requires periodic lubrication after installation — consult the manufacturer service schedule for lubrication intervals and approved grease types.
