Gearboxes & Speed Reducers
Ondrives offers a huge selection of all types of gearboxes and speed reducers manufactured in Freeport, NY or Chesterfield, UK. These include Worm & Wheel, Cross Axis Helical, Right Angle Bevel or Miter, Rack and Pinion, Offset Parallel Spur and In-Line speed reducers and speed increasers. Ondrives is especially capable of manufacturing unique gearboxes to fit your exact need.

Precision Gears
Ondrives manufactures fine pitch precision 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 Gears, Helical Gears, Bevel Gears, Miter Gears, Worm Gears 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.

Precision Fasteners
Ondrives produces precision grade Shoulder Screws in both 303 stainless steel and 416 RC26-32 stainless steel. Our Tipped Set Screws are available with tips in Nylon, Brass or Silver Solder. Use these precision fasteners to prevent damage to expensive shafts. We make stainless steel Thumb Screws with diamond knurled heads or with plastic heads.

Ground Shafts and Dowel Pins
Ondrives manufactures precision ground shafts and dowel pins to 0.0002 inch tolerances in both inch and metric diameters. A wide range of standard lengths are available for same day shipment. Contact our sales staff for a prompt quote on custom diameters, lengths and materials. Our most common materials are 303 stainless steel, 316 stainless steel, 17- 4PH stainless steel, 416 stainless steel and alloy steel.

Custom Mechanical Components
If you can't find the right option for your application among our standard gearboxes, gears, speed reducers, couplings, clutches, and other mechanical components, Ondrives.US can produce custom components to meet your unique requirements.

With a fully-equipped production facility, advanced manufacturing equipment, and comprehensive fabrication capabilities, Ondrives.US can produce parts and components that match your design drawings and deliver the performance and reliability you need.
