Precision Gears

Ondrives manufactures fine pitch gears in inch and metric from AGMA 8 to AGMA 14 quality. Higher quality Ground gears or commercial grade gears are also available. We offer standard or custom Spur, Helical, Bevel, Miter, Worm and Worm Wheel gears.

Shaft Couplings

Misalignment shaft couplings are necessary to compensate for the subtle and sometimes extreme angular, radial and axial misalignment between mating shafts. Without the proper coupling, severe stress is sent back to the bearings or other components and premature failure can result. Ondrives offers the broadest range of misalignment shaft couplings. Our experienced engineers will assist you in finding the proper one for your application.
