Browning 765813 Pillow Block Bearing 1-15/16 in Air Handling

Product Description

The BROWNING 765813 is a cast iron pillow block bearing designed for air handling applications in HVAC and industrial fan systems. Built on the VPS 200 Series platform, it accepts a 1-15/16 inch straight bore shaft and uses a set screw lock type to secure the shaft in position. The bearing insert is manufactured from 52100 bearing steel and is rated for a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds. With an overall length of 8 inches and an overall height of 4-9/16 inches, this unit is sized for fan shafts and blower assemblies found in commercial and light industrial air handling equipment.

This pillow block is suited for installation on blower assemblies, air handling units, and fan decks where a two-bolt, base-mounted bearing housing is required. The VPS 200 Series is commonly found in commercial air handling units, industrial ventilation fans, and HVAC blower sections. The 6-3/16 inch distance between mounting hole centers and a base-to-center height of 2-1/4 inches accommodate standard fan deck mounting configurations. Maximum operating speed is rated at 3,000 RPM, making it appropriate for most belt-driven HVAC fan applications.

Installation Notes

Installation is typically performed by licensed HVAC mechanics or millwrights. Disconnect and lock out all electrical power to the fan or air handling unit before removing or installing bearing assemblies. Ensure the mounting surface is flat and clean before torquing the base bolts, and confirm shaft alignment before final tightening of set screws. Refer to applicable ANSI and OSHA lockout/tagout procedures when servicing rotating equipment.
