Sprockets for Miniature Roller Chain
Often used in electronic equipment, instrumentation devices, printers, and other compact machinery, these sprockets are made for use with our miniature roller chain.
Stainless steel sprockets are corrosion resistant for use in harsh environments. Mount them onto your shaft and secure with a set screw.

MXL Series Lightweight Timing Belt Pulleys
Made from polycarbonate, these pulleys are useful in applications with weight constraints. All are MXL series (miniature extra light) and have trapezoidal teeth. The teeth match up with the grooves along the inside diameter of a timing belt in order to move components forward or backward. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

Plastic Gears and Gear Racks—14 1/2° Pressure Angle
A former industry standard, 14½° pressure angle gears are often found on older machinery. Made of plastic, they run quieter than metal gears and have good corrosion and chemical resistance. They’re 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.
For components to mesh correctly, they must have the same pressure angle and pitch.

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.
A pawl is required to prevent backward motion.

Plastic Ratcheting Gears
A light duty alternative to metal, these plastic ratcheting gears run quieter than metal gears and have good corrosion and chemical resistance. Used to prevent unwanted motion in spools, clocks, and printers, ratchet gears have sloped teeth that allow motion in one direction and prevent it in the other.
A pawl is required to prevent backward motion.
