Martin 2012 1 Taper Bushing, Sintered Steel, Inch, 1" Bore, 2.75" OD, 1.25" Length

This Martin 2012 taper bushing is made of sintered steel and is used for mounting a taper bushed pulley, sheave, or sprocket on a drive shaft. It is flush mounted for reduced mounting width and has a split taper for a tight clamp to shafts. The bushing is made of sintered powder steel for greater strength and wear resistance than plain carbon steel. It is keyed to the shaft to prevent the shaft from rotating in the bushing, and it is interchangeable with taper bushings from various manufacturers. This 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.
