L Series Quick-Disconnect Timing Belt Pulleys
Carry heavy loads without slippage—pulleys mount with quick-disconnect (QD) bushings (sold separately) for a more secure grip on the shaft than set screws. Bushing is not included. Pulleys are L series (light) and have trapezoidal teeth. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

Plastic 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 plastic, they run quieter than metal gears and have good corrosion and chemical resistance. They’re 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.
For components to mesh correctly, they must have the same pressure angle and pitch.
