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

Custom Gears

Custom made gears are designed and manufactured to meet the needs of power transmission applications. These unique power transmission gears are manufactured from metal or plastic, including spur gears, helical gears, bevel gears, Miter gears, and worm gears.

Ondrives.US has been designing, engineering, and manufacturing gearsgearboxes, sprockets, timing pulleys, and other motion transfer components for decades. If our standard gear options do not meet your application requirements, we can produce custom power transmission gears that meet your specifications. We can work from your part prints, reverse engineer a sample part, or work with you to develop a custom gear design that delivers the performance you need.

Custom Made Precision Gears Designed to Your Project Specifications

When creating a custom gear design, selecting the correct pitch, pressure angle, face width, number of teeth, and material is essential. These features control the center distance to the mating gear and the drive system's weight, strength, and longevity.  

Advantages of Working with a Custom Power Transmission Gear Manufacturer

There are times when stock gears and components cannot meet power transmission requirements, such as an older piece of equipment with obsolete parts or custom-built machinery that requires unique components. Or equipment or machinery that is not performing as needed despite using the appropriate size gears. In these cases, a custom gear design will allow your power transmission equipment to operate reliably at its maximum potential.

Precision Quality for Instrumentation Applications or Commercial Quality for Power Transmission

Our custom options deliver a product that meets your exact power, speed, and torque requirements. You don’t have to worry about limited tooth form, pitch, angle, hub shape, size, or material options. A.G.M.A. high precision quality up to Q14.

Custom gears allow you to achieve unique center-to-center distances and customize the angles, face width, tooth width, and hub size to increase performance. Depending on your design's complexity and the production run's size, custom gears can also save time and money over trying to modify stock parts.
