Browning 767683 Pillow Block Bearing 1-15/16 in Cast Iron

Product Description

The BROWNING 767683 is a cast iron pillow block bearing designed to support rotating shafts in industrial and commercial power transmission applications. It accepts a 1-15/16 inch shaft bore and uses a set screw locking mechanism to secure the shaft in place. The insert is manufactured from 52100 steel, a high-carbon chromium bearing steel chosen for its hardness and fatigue resistance. With a static load capacity of 5,216 pounds and a dynamic load capacity of 7,889 pounds, this unit is suited for moderate-to-heavy radial load conditions. Maintenance technicians, millwrights, and mechanical contractors install this type of bearing in fan assemblies, conveyor systems, pumps, and similar rotating equipment.

This pillow block is used in both new installations and replacement applications across industrial, agricultural, and commercial mechanical systems. It mounts to a flat surface using two fasteners spaced 6-3/16 inches apart on center. The overall assembled height of 4-9/16 inches and base-to-center height of 2-1/4 inches determine shaft centerline elevation from the mounting surface, which is critical for drive alignment. It is appropriate for indoor and protected outdoor environments where a two-bolt pillow block configuration is standard practice.

Key Features

• 1-15/16 inch bore accommodates standard fractional shaft sizes
• 52100 steel insert for high hardness and fatigue resistance under radial load
• Set screw lock type for straightforward shaft retention without adapter sleeve
• Static load capacity of 5,216 pounds and dynamic load capacity of 7,889 pounds
• Cast iron housing for rigidity and vibration dampening in fixed-mount applications
• Two-bolt base with 6-3/16 inch mounting hole center-to-center spacing

Compatibility

Designed as an OEM-style replacement or direct-fit pillow block bearing for two-bolt mounting configurations accepting a 1-15/16 inch shaft bore.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Disconnect and lock out all power to the drive system before removing or installing bearings. Ensure the mounting surface is flat and clean before torquing fasteners to prevent housing distortion. Verify shaft alignment and check set screw engagement after initial run-in per standard mechanical maintenance practice.
