SH-Style QD Bushing 3SHSB 1-3/8″ Bore Split Taper Industrial Shaft Mount The SH-Style Quick Detachable (QD) Bushing 3SHSB with a 1-3/8″ bore is engineered for secure and efficient mounting of components such as sheaves, pulleys, and sprockets onto shafts in industrial applications. Its split taper design ensures a tight, uniform grip, facilitating both installation and removal. Key Features Material: Constructed from high-strength steel, offering durability and resistance to wear. Bore Diameter: Precisely machined to 1-3/8 inches, ensuring a snug fit on corresponding shafts. Flange Diameter: Measures 2-11/16 inches, providing ample surface area for secure attachment. Barrel Diameter: 1.871 inches, designed for optimal alignment and load distribution. Overall Length: 1-1/4 inches, accommodating various mounting configurations. Keyway Size: 5/16 x 5/32 inches, enhancing torque transmission and preventing slippage. Number of Bolt Holes: Equipped with three bolt holes, facilitating a balanced and secure mount. Screw Size: Utilizes 1/4-20 x 1-3/8 inch screws, standard for ease of replacement and maintenance. Torque Rating: Capable of handling up to 3,500 in-lbs, suitable for demanding industrial applications. Design and Functionality The split-through flange and taper design of the SH-Style QD Bushing provide a true clamp on the shaft, equivalent to a shrink fit. This design ensures a secure hold, minimizing the risk of slippage under load. The bushing’s versatility allows for mounting the same mating part on shafts of different diameters and the mounting of different sheaves on the same shaft using the same bushing. Installation and Maintenance Installation is streamlined with the bushing’s six-hole drilling pattern, making the process quick and straightforward. The precise taper provides proper wedging action, and the saw cut through the flange and taper ensures a true clamp fit. Cap screws are used to secure the bushing to the sheave and to remove the bushing from the sheave, permitting four-way mounting and easy removal when necessary. For optimal performance and longevity, ensure that the bushing is installed according to manufacturer guidelines, and regularly inspect for signs of wear or misalignment.
