The current industry standard, gears with a 20° pressure angle have thicker, stronger teeth than gears with a 14½° pressure angle.

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.

Reduce speeds where noise, corrosion, and frequent lubrication are a concern. Compared to metal gears, these nylon gears run more quietly, won't rust, and don't need to be lubricated.

Made of nylon, these sprockets are lightweight, quiet, and corrosion resistant.

Made from polycarbonate, these pulleys are useful in applications with weight constraints.

These pulleys spin freely on built-in ball bearings to maintain tension for reduced wear and vibration.
