Browning 767641 Pillow Block Bearing 1-3/16 in Id Cast Iron

Product Description

The BROWNING 767641 is a cast iron pillow block bearing designed to support rotating shaft applications in industrial and mechanical drive systems. It carries an inside diameter of 1-3/16 inches and uses an eccentric lock type to secure the shaft. The bearing insert is made from 52100 steel and delivers a static load capacity of 2,567 pounds and a dynamic load capacity of 4,381 pounds. The overall assembly measures 6-3/16 inches in overall length and 3-5/32 inches in overall height. Millwrights, maintenance mechanics, and industrial equipment technicians install this type of unit bearing in conveyor systems, fan shafts, pump drives, and general power transmission applications.

This pillow block bearing is suited for use in light to medium-duty industrial machinery where shaft diameters of 1-3/16 inches are specified. The eccentric locking collar provides a straightforward method of securing the bearing to the shaft without requiring adapter sleeves. Mounting hole centers are spaced 4-5/8 inches apart, and the base-to-center height is 1-9/16 inches, making it compatible with standard mounting plates and fabricated frames in typical industrial installations.

Compatibility

Designed as an OEM-style replacement pillow block bearing for industrial shaft applications requiring a 1-3/16 inch bore with eccentric locking collar and cast iron housing.

Installation Notes

Installation should be performed by a qualified millwright or maintenance mechanic. De-energize and lock out all power to the equipment before removing or installing any bearing. Ensure the mounting surface is clean and flat before torquing fasteners, and verify shaft diameter tolerance matches the bearing bore specification before assembly. Follow applicable machinery safety standards and manufacturer alignment procedures during installation.
