Industrial S1-2-5/8 Taper Lock Bushing

The Industrial S1-2-5/8 Taper Lock Bushing is a double split taper mounting hub that securely attaches pulleys, sprockets, and sheaves to a 2-5/8 in shaft, delivering precise concentricity and strong holding power for high-torque power transmission applications. It uses a conventional split-taper mounting with a finished bore, three 1/2 in screws, and a 5.375 in bolt circle on a flange outer diameter of 6.375 in; overall dimensions include a 4.375 in through bore length, a large-end barrel of 4.625 in and a small-end barrel of 4.418 in. The bore is 2-5/8 in, with a keyway of 5/8 x 5/16 in, and the bushing is offered in materials such as sintered steel or ductile iron depending on manufacturer. Commonly used in conveyors, pumps, fans, compressors, mixers, crushers, and other industrial drive systems where pulleys, sheaves, or sprockets must be securely mounted to a shaft.
