Acetal and aluminum construction makes these pulleys useful in weight-sensitive applications. All are XL series (extra light) and have trapezoidal teeth. Select a pulley with a maximum belt width that’s the same or larger than your timing belt width.

The current industry standard, these 20° pressure angle gears have thicker, stronger teeth than 14½° pressure angle gears. 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/module.

Acetal gears are best suited for use in light duty machines or for prototyping.

Acetal gear racks absorb less water than nylon racks, so they’re less likely to swell.

These plastic gears are lighter and quieter than metal gears—pair them with metal worms for lubrication-free operation. Worm gears use screw threads to make large reductions to shaft speed while transmitting motion at a right angle. They transmit motion from worm to gear and cannot be reversed. For gears and worms to mesh correctly, they must have the same pressure angle, pitch/module, number of thread starts, and thread direction.

Speed ratio is the ratio by which output shaft speed is reduced. As speed decreases, torque increases.

Acetal gears are lightweight, and resist corrosion and chemicals. They absorb less moisture than nylon gears, so they’re less prone to dimensional changes. They’re best suited for light duty applications, such as prototyping.

Connect two shafts at a right angle without changing shaft speed or torque. Made of plastic, these gears run quieter than metal gears and have good corrosion and chemical resistance.

For two gears to mesh correctly, they must have the same pressure angle, pitch/module, and number of teeth.

Acetal gears absorb less moisture than nylon gears and are less prone to dimensional change. They’re best suited for use in light duty applications such as prototyping.

Conveyor chain is made of plates that flex on their connecting hinges. Also known as sprocket-driven conveyor belting.

Side-flex belts have tabs on the bottom that keep the belt from lifting off the track when traveling through curved sections of conveyor.

Acetal plastic belts are FDA compliant.
