Browning R2-1 3 4 Split Taper Bushing Keyed Bore

Browning R2-1 3/4 Split Taper Bushing with Keyed Bore is an R2-series mounting bushing designed to couple a hub or driven member to a shaft with a smaller diameter while preserving concentricity and a keyed drive. This 1-3/4 in bore bushing measures 4 7/8 in long overall and uses a 4 5/8 in bolt circle; it features a 3/8 x 3/16 in keyseat and accommodates three cap screws sized 3/8 in diameter with a 1 3/4 in length. The through-bore length is 4.88 in, and the flange has a thickness of 5/8 in. The bushing employs a 3/4 in per foot taper on the barrel to create the self-locking engagement between the shaft and the mounted member, while the solid flange and double-split barrel help maintain concentricity. Construction materials are listed as sintered steel or ductile iron, providing robust wear performance in industrial applications. Typical uses include fans, blowers, conveyors, pumps, mixers, crushers, conveying equipment, shaker and sorters, and saws, where a reliable, keyed drive is required to transfer torque from the shaft to the connected component.
