Browning 767817 Pillow Block Bearing 1.5 in Id Cast Iron

Product Description

The BROWNING 767817 is a cast iron pillow block bearing in the VPS 200 series, designed to support rotating shafts in industrial and mechanical drive applications. It accepts a 1.5-inch straight bore shaft and uses a ball bearing insert made from 52100 bearing steel secured with a set screw lock. The housing spans 7.125 inches overall in length and stands 4 inches tall, with a base-to-center height of 2 inches. Static load capacity is 4,467 pounds and dynamic load capacity is 7,340 pounds. Maximum rated speed is 3,500 RPM. This unit is installed by millwrights, maintenance mechanics, and mechanical contractors in conveyor, pump, fan, and general power-transmission systems.

The 767817 is suited for residential and light commercial mechanical equipment as well as industrial machinery where a two-bolt pillow block mount is required. The 5.375-inch center-to-center bolt hole spacing fits standard mounting patterns. The 1.5-inch bore accommodates common shaft sizes found in blower assemblies, conveyor drives, and pump shafts. The bearing insert width of 1.9375 inches provides stable lateral support across a range of load conditions.

Installation Notes

Installation is typically performed by a millwright or maintenance mechanic. De-energize and lock out all power to the driven equipment before removing or installing this bearing. Align the shaft carefully before tightening set screws to avoid inducing preload or misalignment stress on the insert. Verify bolt hole pattern matches the mounting surface before final installation, and apply appropriate fastener torque per the equipment manufacturer's guidelines.
