<div class="full-description"> <p><strong>Material</strong></p> <ul> <li><strong>Body</strong>: A2017</li> <li><strong>Screw</strong>: SCM435 Socket head cap screw, black oxide coating</li> </ul> <p><strong>Features</strong></p> <ul> <li>Backlash less pulley. Backlash per tooth is 0.</li> <li>Ideally suited to small precision instruments.</li> <li>A socket head cap screw comes with all pulleys.</li> <li>Recommended dimensional deviations for pitch diameter are h6 and h7.</li> <li>Bore and keyway modifications are available on request.</li> </ul> <p><strong>Notes:</strong><br /> 1) Moment of inertia is based on the maximum shaft bore<br /> 2) Please ensure the torque rating of the smallest pulley is greater than your required operating torque</p> </div>
