This Martin Q3 MST split taper bushing is made of ductile iron and is used for mounting a split taper bushed pulley, sheave, or sprocket on a drive shaft. It has a solid flange, and the barrel is split in two places to improve concentricity and provide strong clamping on the shaft. The bushing is made of ductile iron for greater strength than gray cast iron and resistance to wear, galling, and corrosion. It is keyed to both the shaft and the drive component to provide higher torque carrying capacity and the ability to hold if the fasteners become loose, and it is interchangeable with split taper bushings from various manufacturers. This split taper bushing is used in automobiles, construction equipment, agricultural machinery, and home appliances, among others.Bushings are cylindrical parts used to mount pulleys, sheaves, sprockets, or other components to drive shafts for the transmission of mechanical power. Most bushings are split and have a tapered outside surface so they will clamp to the shaft when tightened against the tapered bore of the driven component. They are made of durable metals such as cast iron and steel. Bushings are used in automobiles, construction equipment, and machine tools, among others.Martin Sprocket & Gear manufactures power transmission and conveying products. The company, founded in 1951 and headquartered in Arlington, TX, provides tools that meet American National Standards Institute (ANSI), National Aerospace Standard (NAS), and Deutsches Institut für Normung (DIN) standards.
