Quick-Grip Screw-Clamp Bushings
Also known as Trantorque bushings, these tighten with a twist of the collar nut—no screws needed. As you tighten the collar nut, the inner sleeve contracts onto the shaft and the outer sleeve expands to hold your sprocket, pulley, or gear.

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.
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.

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.
