Browning 767619 4-bolt Flange Bearing 1-3/8 in Id Cast Iron

Product Description

The BROWNING 767619 is a 4-bolt flange bearing unit in the VF4S 100 series, designed to support rotating shafts in industrial and commercial mechanical drive applications. The cast iron housing accepts a 1-3/8 inch bore and measures 4-5/8 inches in overall length and 4-5/8 inches in overall height. The bearing insert is 52100 steel with a set screw lock and carries a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds. Maximum operating speed is 2,500 RPM. This unit is installed by millwrights, maintenance mechanics, and HVAC or industrial equipment technicians wherever shaft support and load management are required.

The VF4S-122 is suited for use in conveyor systems, fan and blower assemblies, pump drives, and other industrial or commercial mechanical equipment requiring a rigid 4-bolt flange mount. Mounting hole centers are spaced 3-5/8 inches apart, with a bolt size of 1/2 inch. The hub diameter is 3-5/8 inches and the base-to-center distance is 0.859 inches, making this unit compatible with standard VF4S 100 series mounting layouts. Lubrication is required during installation and as part of routine service intervals.

Installation Notes

Installation is performed by qualified millwrights or maintenance mechanics. Shut down and lock out all power to the drive system before removing or installing any bearing unit. Align the shaft carefully before tightening set screws to avoid premature wear, and ensure the mounting surface is flat and clean before bolting down. Apply appropriate grease to the bearing insert prior to initial startup and follow the equipment manufacturer's recommended re-lubrication intervals.
