Browning 767739 Pillow Block Bearing 1 Inch Cast Iron

Product Description

The BROWNING 767739 is a VPLS 100 series pillow block bearing designed for industrial shaft support applications. It features a 1 inch straight bore and a cast iron housing with a ball bearing insert made from 52100 bearing steel. The two-bolt block measures 5.5 inches overall length and 2.6875 inches overall height, with a set screw locking mechanism to secure the shaft in place. With a static load capacity of 1,651 pounds and a dynamic load capacity of 2,801 pounds, this unit handles moderate to heavy radial loads in rotating equipment. Licensed HVAC, mechanical, and industrial technicians install this type of bearing in fan assemblies, conveyors, pumps, and blower shafts.

This pillow block bearing is suited for use in light to medium industrial equipment where a two-bolt mounting configuration is required. The VPLS 100 series is commonly found in HVAC blower systems, agricultural equipment, material handling conveyors, and general-purpose rotating shaft assemblies. The 4.125 inch center-to-center bolt spacing and 1.313 inch base-to-center height allow for straightforward mounting on standard equipment frames. Maximum rated speed is 3,500 RPM, making it appropriate for most belt-driven fan and pump applications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright familiar with rotating equipment service. Shut down and lock out the equipment at the power source before removing or installing any bearing assembly. Ensure the mounting surface is flat and clean before torquing bolts, and align the shaft carefully before tightening set screws to avoid premature bearing wear. Consult the equipment manufacturer's documentation for shaft tolerance and lubrication requirements specific to the application.
