AT3 belt sizes in truly endless technology. Truly endless timing belts have no weld zone and the belt tension member is uninterrupted for approximately 100% increased tensile strength compared with a spliced and welded timing belt. AT3 truly endless timing belts are available in belt widths of 6, 10, 16, 25, and 32 mm. The minimum belt length is 720 mm and the maximum belt length is 1,701 mm. The tension member is available in steel or stainless steel. The allowable tensile strength varies from 190N to 1400N, depending on the belt width. AT3 pitch timing belts are ideal for small power drives requiring a high tooth sheer strength and are suited for high-speed applications. AT3 also comes with optional nylon facing on the tooth side for reducing the coefficient of friction. Zero backlash pulleys are available for bidirectional belt drives.
