Newly Re-designed P-Series Gearbox improves Backlash, Corrosion Resistance and Center Distance between Input and Outputs! 

Precision Gears

Precision gears are critical mechanical components used in devices ranging from watches to the drive wheels of tanker ships. Some precision gear configurations also change the direction of rotation, while others can change the angle of axis. Virtually any ratio reduction can be achieved with the right combination of precision gears. Please note that, when selecting any style of precision gear, the pitch and pressure angles of mated gears must be identical.  

Precision Gears for All Applications

Ondrives.US has decades of experience as a precision gear manufacturer, producing fine pitch and coarse pitch gears in inch and metric sizes to meet AGMA (American Gear Manufacturers Association) standards and in styles and configurations to meet any application and performance requirements. We offer spur gears, worm gears, helical gears, and much more, including modified and custom precision gears that are tailored to your unique needs. Are you looking for a specific part?

Precision Gears: Metric Series

We also offer precision gears in metric sizes. Our Metric Series precision gear lineup includes spur gears, spur pinion shafts, and spur gear racks, helical gears, straight cut bevel gears, worms and wormwheel gears, and more.

Precision Ground Gears

The process used to create precision ground gears gives them a more precise finish than cut or machined gears, making ground gears better suited to use with smaller components and in high precision applications. We offer a full line of ground precision gears, including spur gears, splined spur gears, and spur gear racks, 15° helical gears and 19°31’ helical gears, worms and wormwheel gears, and more.

Modified & Custom Gears 

Most of our precision gears can be modified to fit your unique application and performance requirements. We can also provide completely custom gears that are manufactured to your exact specifications. Contact us to specify the modified or custom gears you need.
