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. Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear’s teeth increases its wear resistance.
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.
