Browning U0-4-3 4 Split Taper Bushing

Browning U0-4-3 4 Split Taper Bushing is a U0-series split-taper bushing designed to join a hub to a shaft in power-transmission assemblies with a self-locking taper. This version features a 4.000 in bore, a 4.9375 in length through the bore, and an 8.375 in outer diameter, and it is offered in ductile iron or gray iron. The taper is 3/4 inch per foot on diameter, providing a secure torque transfer when installed in compatible Browning hubs. The U0 family is designed for high-torque, high-precision mounting in industrial equipment, and bushings in this series are commonly used to retrofit or assemble pulleys, gears, and sprockets to shafts. This 4-inch bore model is one of Browning's standard through-bore configurations, enabling straightforward replacement and compatibility with a range of standard hub bore sizes across machinery like conveyors and milling equipment.
