Browning 767377 VPE-220 Pillow Block Bearing 1-1/4 in Bore

Product Description

The BROWNING 767377 is a VPE-220 series pillow block bearing designed for industrial shaft support applications. It features a 1-1/4 inch straight bore and a cast iron housing with an eccentric lock collar for positive shaft retention. The bearing insert is manufactured from 52100 bearing steel and is rated for a static load capacity of 3,493 pounds and a dynamic load capacity of 5,782 pounds. With a maximum operating speed of 4,000 RPM, this unit suits moderate- to high-speed rotating equipment in manufacturing, agricultural, and mechanical power-transmission systems. Licensed millwrights, maintenance mechanics, and equipment technicians are the primary installers.

The BROWNING 767377 fits applications requiring a two-bolt pillow block in the VPE 200 series footprint. Its overall height of 3-11/16 inches and overall length of 6-3/4 inches make it suitable for retrofits and new installations on conveyor systems, fans, pumps, and other shaft-driven equipment in light to medium industrial environments. The 5-inch center-to-center mounting hole spacing and 1-7/8 inch base-to-center height are key layout dimensions when planning the mounting surface.

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 unit. Ensure the mounting surface is flat and clean before torquing the base bolts to prevent housing distortion. After seating the bearing on the shaft, tighten the eccentric lock collar in the direction of shaft rotation to secure the assembly.
