Browning 767405 Tapped Base Bearing Insert Cast Iron

Product Description

The BROWNING 767405 is a tapped base bearing unit in the VTBS 200 series, designed to support rotating shafts in fixed-mount industrial and mechanical drive applications. It accepts a 0.625-inch straight bore shaft and houses a 52100 bearing steel ball insert secured by a set screw. The cast iron housing provides rigid support with a static load capacity of 1,444 pounds and a dynamic load capacity of 2,611 pounds. Rated to 7,500 RPM, this unit handles moderate-speed shaft applications found in HVAC fan assemblies, conveyor drives, and light industrial equipment. Licensed mechanics and millwrights are the typical installers.

This tapped base bearing is suited for applications where a two-bolt, low-profile mount is required on a flat surface. The 2-inch center-to-center bolt spacing and 1.3125-inch base-to-center height make it a compact solution for belt-driven blower shafts, pump mounts, and similar rotating equipment in both commercial and light industrial settings. It is part of the VTBS 200 series, which uses standardized insert geometry for consistent replacement across drive system rebuilds.

Compatibility

Designed as an OEM-style replacement or new-install tapped base bearing unit for rotating shaft assemblies requiring a 0.625-inch straight bore and two-bolt flat-surface mount in the VTBS 200 series configuration.

Installation Notes

Installation should be performed by a qualified mechanic or millwright with the drive system fully de-energized and locked out per applicable LOTO procedures before mounting. Align the shaft carefully before tightening the set screw to avoid preloading the bearing. Verify bolt hole alignment and surface flatness before torquing the mounting hardware. Consult equipment OEM documentation for any application-specific lubrication requirements prior to commissioning.
