Browning B 1-15 16in Split-Taper Bushing

The Browning B Series Split Taper Bushing, model B 1, is a high-torque, double-split bushing designed to mount a 1-inch bore shaft in pulleys, sprockets, and other belt-drive components. It features a double-split barrel for true concentricity and positive shaft clamping, a 3-1/8 in bolt circle, and a 1/4 x 1/8 in keyway for a secure drive. The bushing measures 1-15/16 in in overall length with a through-bore length of 1.94 in and a taper dimension (T) of 1-7/16 in, enabling a robust self-locking grip on the shaft (3/4 in per foot). It is offered in sintered steel or ductile iron, and rated for 192 in-lbs wrench torque. Three cap screws (5/16 x 1-1/4 in) are included for installation, with a large diameter of 2-5/8 in and a small diameter of 2.5567 in, weighing approximately 3.03 lb. This Browning bushing is part of the B Series and is suited for high-torque power transmission tasks in belt-drive hubs and pulleys, providing secure mounting for 1 in bore components in industrial applications such as conveyors, fans, and other driven machinery.
