| Product Description | Move belts forward and backward or stop and start them in precise positions, especially in areas where rust is a concern. The curved teeth on these high-torque drive (HTD) pulleys have more surface contact with belts than traditional trapezoidal teeth, which allows you to apply more torque without damaging belts. These teeth fit together seamlessly to prevent backlash, or unwanted movement of the belt on the pulley, for a smooth, quiet cycle. These pulleys are often used in 3D printing, machine tool drives, robotics, and other applications where precision is essential. They are also known as curvilinear belt pulleys. Pair pulleys with an HTD timing belt that has the same pitch. The width of your belt should not be larger than the maximum belt width listed. Stainless steel pulleys can be wetted repeatedly without rusting or staining. |
