Browning 3695103 Type B Sprocket Bushing 1-5/16 in Bore

Product Description

The BROWNING 3695103 is a Type B sprocket bushing designed to mount sheaves and sprockets onto shafts in mechanical power transmission systems. It features a 1-5/16 inch bore with a 5/16 inch keyway width and 5/32 inch keyway depth, providing a secure, keyed connection that resists rotational slippage under load. The outer diameter ranges from 2.557 to 2.625 inches, making it compatible with B5V sheave configurations. This bushing is a standard component installed by millwrights, maintenance technicians, and HVAC mechanics when assembling belt-drive systems on fans, blowers, pumps, and similar rotating equipment.

This bushing is suited for use in industrial and commercial mechanical drive assemblies where B5V sheaves are specified. Typical applications include belt-driven HVAC fan systems, industrial blowers, and pump drive trains where a reliable, removable shaft-to-sheave connection is required. The Type B bushing profile is a widely recognized standard in split-taper and companion bushing systems, allowing straightforward installation and removal without damaging the sheave or shaft.

Installation Notes

Installation should be performed by a qualified millwright or mechanical technician. Always de-energize and lock out the drive system before beginning any bushing or sheave work, following LOTO procedures per applicable safety standards. Ensure the shaft and bore are clean and free of burrs before seating the bushing. Do not over-tighten fasteners without reference to applicable torque specifications provided in the manufacturer documentation supplied with the component.
