Browning 767850 Pillow Block Bearing 1-1/4 in Cast Iron

Product Description

The BROWNING 767850 is a cast iron pillow block bearing designed for industrial shaft support applications. It uses a ball bearing insert made from 52100 bearing steel and accepts a 1-1/4 inch straight bore shaft secured with a set screw lock. The housing mounts on two bolts with 4-5/8 inches between mounting hole centers. Static load capacity is 2,567 pounds and dynamic load capacity is 4,381 pounds, making it suitable for moderate-to-heavy radial load conditions. Part of the VPS 200 Series, this unit is installed by millwrights, maintenance mechanics, and industrial technicians in conveyor, fan, pump, and general power transmission applications.

The 767850 is intended for use in industrial and commercial machinery where a two-bolt pillow block mount is required. It fits horizontal shaft installations requiring a 1-1/4 inch bore. The overall height is 3-9/32 inches and the base-to-center height is 1-11/16 inches, which determines shaft centerline elevation from the mounting surface. Overall length is 6-3/16 inches. The bearing insert width is 1-3/4 inches and bearing length is 1-1/2 inches. Maximum rated speed is 4,500 RPM.

Installation Notes

Installation is typically performed by a qualified millwright or maintenance mechanic. Shut down and lock out all power to the drive system before removing or installing any bearing assembly. Align the shaft carefully before tightening set screws to avoid premature bearing wear. Follow OSHA lockout/tagout procedures and applicable machinery safety standards during service.
