<div class="full-description"> <p><strong>Material</strong></p> <ul> <li><strong>Body</strong>: Anodised Aluminium alloy (A2017).</li> <li><strong>SetScrews</strong>: SCM435 black oxide coating.</li> <li><strong>Sleeve</strong>: Polyurethane.</li> <li><strong>Sleeve Durometer Hardness (Shore A)</strong>: 98 (Red disc - RD), 92 (White disc - WH), 80 (Blue disc - BL).</li> <li><strong>Operating temperature Range</strong>: -20°C to +60°C.</li> <li>Rated and max. torque capacities are decreased in case of use in high ambient temperatures. If ambient temperature exceeds 30°C, adjust torque capacity.</li> </ul> <p><strong>Features</strong></p> <ul> <li>For use with stepper motors and some servo and general purpose motors.</li> <li>Excellent flexibility - torsional vibration can be absorbed as well as parallel and angular misalignments.</li> <li>Excellent resistance to oil, and electrical insulation.</li> <li>Can transmit generally higher torque than metallic spring couplings.</li> <li>Compression type coupling assembled by pressing an elastic polyurethane sleeve into hubs on both sides for zero backlash in low torque application.</li> <li>Can be used as a flexible coupling in a high torque applications.</li> <li>Identical clockwise & anti-clockwise rotational characteristics.</li> <li>Finished bore product - models with two different end bores also in stock.</li> <li>Setscrews supplied. Bores of 3 or 4mm only have 1 setscrew.</li> <li>Recommended tolerance on shaft diameters is h6 and h7.</li> <li>Complete absorption of eccentricity, angularity and end-play by spring actions.</li> </ul> <p><strong>Ordering:</strong></p> <p>The MJT coupling can be bored out, but not keywayed.<br /> MJT-K Keywayed couplings can be ordered as specials, but a minimum order quantity may apply.</p> <p>† Moment of inertia and mass figures are based on maximum shaft bores.</p> </div>
