<h2>Overview</h2>
<p>The <strong>Martin 2012 1 1/2 taper bushing</strong> is a precision shaft-mounting component engineered for reliable mechanical power transmission. 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. Standard bore type with minimum bore size of 1.5″ and maximum bore size of 2″, this taper lock bushing accommodates flexible bore requirements across a range of drive applications.</p>
<h2>Key Features</h2>
<ul>
<li>Made of sintered powder steel for greater strength and wear resistance than plain carbon steel</li>
<li>Taper lock style bushing with no flange, ideal for flush mounted applications</li>
<li>Split taper provides tight clamp to shafts</li>
<li>Two mounting cap screws for secure component installation</li>
<li>Keyed to the shaft to prevent rotation in the bushing</li>
</ul>

<h2>Typical Applications</h2>
<p>This taper bushing is used in automobiles, construction equipment, agricultural machinery, and home appliances, wherever cost-effective, split-taper component mounting is required. 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.</p>
