Keep constant tension on your drive with these sprockets that press against your metric ISO roller chain to take up slack and reduce wear and vibration. They rotate freely on built-in ball bearings, which are double sealed to keep dirt out, and are for use with roller chain tensioners. All come with a finished bore that fits directly onto your shaft—no need for machining. These sprockets meet ISO 606, which is an international standard for dimensions and materials.

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.
Bushing-mount pulleys grip the shaft more securely than press-fit pulleys, but require a quick-disconnect (QD) bushing (not included).
