Split-Tapered Bushings
The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings. They're for use with split-tapered sprockets and pulleys of the same bushing style. As you tighten the included screws, the bushing grips the shaft and pulls it into the sprocket or pulley.
Bushings with a machine key fit into a matching keyway on a sprocket or pulley for high-torque applications.

Self-Adjusting Spring Bushings
A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit. Made of spring steel, they flex under stress and shock and can handle oscillating or slow rotational motion.

Metal 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 carbon steel, they have high strength and are better than plastic gears and gear racks for high-load, high-speed, and heavy duty applications.
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.
Gears with machinable bore have a large hub diameter so you can machine them to fit your shaft.
Gears with teeth that are not hardened can be hardened to fit your application. Hardening a gear's teeth increases its wear resistance.
