Browning 767933 4-bolt Flange Bearing 1-3/16 Inch Bore

Product Description

The BROWNING 767933 is a 4-bolt flange bearing unit designed for industrial and mechanical drive applications requiring a secure, rigid shaft mount. Built around a 1-3/16 inch bore and a cast iron housing, this unit uses a set screw lock to fix the shaft in position. It carries a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds, making it suitable for moderate to heavy radial loading in rotating equipment. The 52100 steel insert provides wear resistance at the bearing surface. Mechanical contractors, millwrights, and HVAC equipment installers commonly fit this style of bearing to fan shafts, blower assemblies, and conveyor drives.

This flange unit fits residential and light commercial equipment as well as industrial machinery where a 4-bolt mounting pattern is specified. The overall length and height are each 4-5/8 inches, with mounting hole centers spaced 3-5/8 inches apart, conforming to standard bolt patterns for fan and blower shaft support. The 1/2 inch bolt size is common across most field installations. Applications include belt-driven blower shafts, air handling unit fans, and general power transmission assemblies where a rigid flange mount is required.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit flange bearing for equipment using a 1-3/16 inch shaft diameter and a 4-bolt flange mount pattern in HVAC, blower, and general power transmission applications.

Installation Notes

Installation is typically performed by a licensed millwright, mechanical contractor, or HVAC technician. Disconnect and lock out all power to the equipment before removing or installing the bearing unit. Ensure the shaft is clean and free of burrs before seating the bore, and tighten set screws in accordance with standard mechanical assembly practice. Verify mounting surface flatness and bolt torque to prevent housing distortion and premature bearing wear.
