Browning 767654 2-bolt Flange Bearing 1.5 Inch Id

Product Description

The BROWNING 767654 is a 2-bolt flange bearing unit designed for industrial shaft support applications. Identified by model VF2E-224, it accepts a 1.5-inch inside diameter shaft and houses a ball bearing insert made from 52100 steel with an eccentric lock collar. The cast iron housing measures 6.75 inches overall length by 4.125 inches overall height and weighs 4.46 pounds. Static load capacity is 4,467 pounds and dynamic load capacity is 7,340 pounds, making it well suited for moderate-to-heavy radial load duty. Maximum rated speed is 3,500 RPM. Lubrication is required during installation and at regular service intervals.

This flange bearing is used in industrial and commercial mechanical drive systems where a shaft must be mounted to a flat surface using a two-bolt pattern. Typical applications include conveyor drives, blower shafts, pump mounts, agricultural equipment, and general power transmission assemblies. The eccentric lock design allows secure shaft clamping without set screws damaging shaft surfaces. Mounting hole centers are spaced 5.656 inches apart on 0.5-inch bolt hardware. The base-to-center distance is 1.375 inches, and the flange height is 0.625 inches, which aids in planning shaft centerline elevation during equipment assembly.

Key Features

• 1.5-inch bore accepts standard mid-size shaft diameters common in industrial drive trains
• Cast iron housing provides rigid, vibration-resistant support in demanding environments
• 52100 steel ball bearing insert rated to 4,467 lb static and 7,340 lb dynamic load capacity
• Eccentric lock collar secures shaft without requiring machined keyways or set-screw flats
• Maximum 3,500 RPM operating speed suits a wide range of belt and chain drive configurations
• 2-bolt mount pattern with 0.5-inch bolt hardware simplifies installation on standard fabricated frames

Compatibility

Designed as an OEM-style replacement or direct-fit flange bearing for industrial power transmission assemblies requiring a 1.5-inch bore 2-bolt flange unit in the VF2E 20 series.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician familiar with shaft alignment and bearing mounting procedures. De-energize and lock out all power to the drive system before beginning work. Ensure the mounting surface is flat and free of debris before torquing the flange bolts. Apply the specified grease to the bearing insert before startup, and establish a routine re-lubrication interval based on operating speed and load conditions.
