Browning 767388 4-bolt Flange Bearing 2-3/16 in Bore

Product Description

The BROWNING 767388 is a 4-bolt flange bearing unit from the VF4E 200 series, designed for industrial shaft support applications in HVAC equipment, conveyor systems, fans, and other rotating machinery. The unit features a 2-3/16 inch bore with an eccentric lock collar, a cast iron housing, and a 52100 steel ball bearing insert. Static load capacity is 6,601 pounds and dynamic load capacity is 9,752 pounds, making it suitable for moderate-to-heavy radial load applications. Lubrication is required for proper operation. The unit is installed by millwrights, mechanical contractors, and equipment service technicians working on industrial or commercial drive systems.

This flange bearing unit is used in commercial and industrial settings where a rigid, 4-bolt mounting configuration is required. Common applications include belt-driven fan assemblies, blower shafts, pump drives, and conveyor head shafts. The 4-bolt pattern and cast iron housing provide stable, vibration-resistant mounting on structural steel or equipment frames. Maximum operating speed is 2,500 RPM. The VF4E 200 series is intended for installations requiring a standard 2-3/16 inch shaft bore with an overall flange envelope of 6-3/8 inches in both length and height.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Isolate and lock out all power to the drive system before removing or installing any bearing unit. Align the shaft carefully before tightening the 4-bolt flange hardware to avoid preloading the bearing. Seat the eccentric lock collar in the direction of shaft rotation and secure before returning the unit to service. Lubricate per manufacturer interval recommendations before initial startup.
