Bando 669-3M-9 3M HT Timing Belt END CAPS AND TERMINALSBando 669 3M 9 Synchro Link HT (High Torque Synchronous) belts' curvilinear tooth design improves stress distribution to provide high horsepower ratings over a wide speed range and high torque transmission at low speeds. The rounded tooth profile meshes precisely with matching pulley grooves so there is no belt creep or slip to cause speed variation. HT belt drives are 99% efficient, leading to significant energy savings on high horsepower
