Its hollow structure lets cables, air lines or shafts pass through the center, and its zero-play tooth engagement keeps backlash within 20 arc-seconds. It is a good fit for robot joints, rotary tables, small positioners and any precision axis that needs a high ratio in a compact, single stage. Supplied and supported by Robot3T, with engineering help to integrate it into your design.<\/p>\n<a href=\"\/en\/contact\/\" class=\"button primary\" style=\"border-radius:99px;\">\n\t\t<span>Request

\/>Ratio 100 gives the most torque and the finest resolution; ratio 50 gives higher output speed. Tell us your load, speed and motor and we will recommend one.<\/p>\n<p><strong>Can you supply it with a motor, encoder and brake as a complete joint?<\/strong><br \/>Yes. We can match G3TS-20 with a servo motor and driver, or build a complete robot joint module for your project.<\/p>\n<p><strong>Can you modify the flanges or hollow bore?<\/strong><br \/>For volume orders, custom flange and interface designs are possible. Send us your drawing or requirements.<\/p>\n<p><strong>Do you ship outside Vietnam?<\/strong><br \/>Yes.
