Browning 767433 4-bolt Flange Bearing 0.75 in Id Cast Iron

Product Description

The BROWNING 767433 is a 4-bolt flange bearing unit in the VF4S 200 Series, designed for shaft support in industrial and mechanical drive applications. It features a 0.75-inch inside diameter bore with a set screw lock and is housed in a cast iron body, making it suitable for demanding environments. The bearing insert is made from 52100 steel and requires lubrication. Static load capacity is 1,444 pounds and dynamic load capacity is 2,611 pounds. Maximum operating speed is 6,500 RPM. Licensed HVAC, mechanical, and millwright technicians install this unit in belt-drive systems, fan assemblies, and conveyor applications.

The VF4S-212 is used in residential and commercial mechanical systems where a robust, bolt-down flange mount is required. Typical applications include fan shaft support in air handling units, blower assemblies, and light-duty conveyor or drive systems. The 4-bolt mounting pattern provides a stable, square footprint that resists torque and misalignment under load. The 2.5-inch bolt hole center-to-center spacing and 3/8-inch bolt size make it compatible with standard industrial mounting plates and frames.

Installation Notes

Installation is performed by qualified mechanical or millwright technicians. Shut down and lock out all power to the drive system before mounting or removing the bearing unit. Align the shaft carefully before tightening set screws to avoid premature bearing wear. Apply appropriate grease to the bearing insert at initial installation and at regular service intervals per the equipment maintenance schedule.
