Browning 767457 4-bolt Flange Bearing 1.25in Id Cast Iron

Product Description

The BROWNING 767457 is a 4-bolt flange bearing unit designed for general industrial shaft support applications. It houses a ball bearing insert with a 1.25-inch inside diameter and is built into a cast iron housing, making it suitable for moderate to heavy radial load environments. The unit carries a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds, with a maximum operating speed of 4,000 RPM. The bearing insert is manufactured from 52100 steel and uses a set screw lock to secure it to the shaft. Licensed HVAC, mechanical, and industrial maintenance technicians commonly install this style of flange unit on fans, blowers, conveyors, and rotating equipment.

This flange bearing is suited for use in residential and commercial mechanical systems, as well as general industrial machinery where a 4-bolt mounting pattern is required. It fits applications where the shaft requires firm, stationary housing support at a fixed point. The overall length and height are each 4.625 inches, and the distance between mounting hole centers is 3.625 inches, making it compatible with standard 4-bolt flange mounting layouts. Lubrication is required during installation and as part of routine maintenance to preserve insert life and load performance.

Compatibility

Part of the BROWNING VF4S 200 series. Designed as an OEM-style replacement or direct-install 4-bolt flange bearing unit for industrial and mechanical equipment requiring a 1.25-inch bore and 4-bolt flange mount configuration.

Installation Notes

Installation should be performed by a qualified millwright, mechanical technician, or maintenance professional. De-energize and lock out all equipment before mounting or removing bearing units, following applicable OSHA lockout/tagout procedures. Ensure shaft surfaces are clean and free of burrs before seating the insert, and torque all four mounting bolts evenly to manufacturer specifications for the fastener size. This unit requires lubrication at installation and on a scheduled basis thereafter.
