Browning 2TB70 Two-Groove V-Belt Sheave Pulley

2TB70 is a Browning TB Gripbelt double-groove V-belt sheave crafted in close-grain cast iron with a 7.35-inch outside diameter, designed for A- and B-section belts in industrial belt-drive applications. It is a split-taper bushed pulley that requires a Browning QD bushing (Q1) for shaft mounting, and it features a combination groove that allows running either A or B belts in the same sheave for flexible drive configurations. Bore sizes span from 3/4 inch to 2-11/16 inches depending on the installed QD bushing, enabling compatibility with a wide range of shaft diameters. The 2TB70 is part of Browning’s TB Gripbelt line and is commonly used in machinery and equipment that rely on two-belt transmissions, offering robust cast-iron construction and precise tolerances for reliable torque transfer.
