Sprockets for Metric Roller Chain
Designed to meet ISO 606 and DIN 8187 international dimensional standards, these sprockets are for use with compatible ISO and DIN roller chain. They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size.

High-Strength Corrosion-Resistant HTD Timing Belt Pulleys
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.
Aluminum pulleys will not rust in damp or humid environments, but water left on the surface will cause them to corrode.

Metal Gears and Gear Racks—20° Pressure Angle
The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. Compared to plastic gears and racks, they’re better for high-load, high-speed, and heavy duty applications. Also known as spur gears.
Combine gears with different numbers of teeth to change speed and torque in your assembly. Combine a gear and rack to convert rotary motion into linear motion. To minimize your footprint, mount one or more standard gears inside of an internal gear.
For components to mesh correctly, they must have the same pressure angle and pitch/module.
Carbon steel components have hard, strong, and wear-resistant teeth, although they will rust when exposed to moisture and corrosive chemicals. They're best for high-torque machines, like lifting equipment, and heavy duty applications, such as rock crushing. Gears with teeth that are not hardened can be hardened to fit your application.
Stainless steel gears and racks resist rust in damp and wet environments, so they're commonly used in food-processing plants and other areas with frequent cleaning. Gears with a clamping bore have a built-in clamp that securely grips shafts without marring them. Use the included clamping screw to tighten or loosen the grip.

Metal Ratcheting Gears
Compared to plastic gears, these metal ratcheting gears are better for high-load, high-speed, and heavy duty applications. Used to prevent unwanted motion in jacks, tie downs, clutches, and winches, ratchet gears have sloped teeth that allow motion in one direction and prevent it in the other.
Gears with hardened teeth are more wear resistant than gears with teeth that are not hardened.
