Browning 767312 2-bolt Flange Bearing 1.25 in Id

Product Description

The BROWNING 767312 is a 2-bolt flange bearing unit designed for shaft support in light-to-medium industrial and mechanical drive applications. It houses a 52100 steel insert with an eccentric locking collar that secures directly to the shaft without set screws, providing positive shaft retention under radial load. The bore measures 1.25 inches in diameter. The cast iron housing delivers durability in typical factory, HVAC mechanical room, and conveyor environments. Static load capacity is 2,567 pounds and dynamic load capacity is 4,381 pounds. This unit is installed by millwrights, industrial maintenance technicians, and HVAC mechanical contractors during drive system assembly or bearing replacement service.

The 767312 fits into applications requiring a standard 2-bolt flange mount on shaft diameters of 1.25 inches. Typical installations include belt-driven fan assemblies, conveyor tail pulleys, blower shafts, and light industrial rotating equipment where a compact flange profile is required. The 5.5625-inch overall length and 3.125-inch overall height suit standard mounting footprints in both new construction and retrofit scenarios. Mounting hole centers are spaced 4.59375 inches apart, accommodating common steel channel and plate mounting structures.

Key Features

• Eccentric lock collar provides positive shaft retention without set screws damaging shaft surface
• 52100 steel bearing insert for high radial load capacity in industrial service
• Cast iron housing resists deformation under sustained static and dynamic loads
• 2,567-pound static load capacity and 4,381-pound dynamic load capacity
• 2-bolt mounting pattern simplifies installation on channel, plate, or fabricated steel frames
• Compact flange height of 0.53125 inches keeps the shaft centerline close to the mounting surface

Compatibility

Designed as an OEM-style replacement or new-installation 2-bolt flange bearing for shafts with a 1.25-inch diameter in industrial and mechanical drive systems.

Installation Notes

Installation is performed by qualified millwrights or industrial maintenance technicians. De-energize and lock out all drive equipment before removing or installing the bearing unit per OSHA lockout/tagout requirements. Ensure the shaft is clean and free of burrs before sliding the bearing into position, then tighten the eccentric collar in the direction of shaft rotation. Verify shaft alignment across both flange units before final bolt torque to avoid premature bearing wear.
