Machinable-Bore Sprockets for ANSI Roller Chain
For a custom fit on your shaft, these sprockets can be machined to your exact specifications. They come machined to the shaft diameter size listed and are machinable up to the maximum shaft diameter size.
Split-Tapered Bushing-Bore Sprockets for ANSI Roller Chain
Since these sprockets grip bushings more tightly than taper-lock sprockets, they’re often used in high-torque applications. The same sprocket can be used with different shaft diameters; choose a compatible split-tapered bushing with the bore size you need.
Sprockets for P1- and Q1-Style bushings have a keyway that fits a matching key on the bushing.

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.
