Browning 767390 Pillow Block Bearing 2-3/16 in Cast Iron

Product Description

The BROWNING 767390 is a cast iron pillow block bearing designed for shaft support in industrial and commercial mechanical drive applications. It accepts a 2-3/16 inch inside diameter shaft and uses an eccentric locking collar to secure the bearing to the shaft without set screws cutting into the shaft surface. The unit measures 8-13/16 inches overall length and 4-31/32 inches overall height, with a base-to-center height of 2.5 inches. Static load capacity is 6,601 pounds and dynamic load capacity is 9,752 pounds. The 52100 steel insert provides durability under continuous rotational loads. Licensed millwrights, industrial maintenance technicians, and mechanical contractors typically install this bearing in conveyor, fan, pump, and drive shaft assemblies.

This pillow block is suited for mounting on flat surfaces in industrial, agricultural, and commercial mechanical systems where shaft support and alignment are required. Mounting hole centers are spaced 6-15/16 inches apart, making hardware layout straightforward on standard channel or plate frames. The cast iron housing resists deformation under sustained radial and thrust loads. It is commonly installed in belt-driven conveyor lines, blower assemblies, pump skids, and material-handling equipment requiring reliable, serviceable bearing support at mid-span or end-of-shaft positions.

Key Features

• 2-3/16 inch bore accommodates standard mid-range industrial shaft diameters
• Eccentric lock collar secures bearing to shaft without damaging shaft surface
• 6,601 pound static load capacity and 9,752 pound dynamic load capacity for demanding applications
• 52100 steel insert delivers high hardness and fatigue resistance under rotational load
• Cast iron housing provides rigidity and dimensional stability at mounting surface
• 6-15/16 inch between mounting hole centers for straightforward bolt pattern layout

Compatibility

Designed as an OEM-style replacement pillow block bearing for industrial and commercial mechanical drive systems requiring a 2-3/16 inch bore eccentric-lock cast iron housing unit.

Installation Notes

Installation is typically performed by licensed millwrights or qualified industrial maintenance technicians. De-energize and lock out all power to the drive system before removing or installing any bearing unit per OSHA lockout/tagout procedures. Ensure the mounting surface is flat and clean before torquing mounting fasteners, and verify shaft alignment across both bearing positions before final tightening. Do not use the eccentric collar to force a misaligned shaft into position.
