Gears

Compared to nylon gears, these metal ratchet 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.

Hardened—Gears with hardened teeth are more wear resistant than gears with teeth that are not hardened.

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.
