In the absence of suitable standard gears to meet your requirements, you can opt for custom-made gears. According to the application, you can customize the gear based on its dimension and material. There are various types of gears available in the market such as bevel gears, crown wheel and pinion, helical gears, miter gears and spur gears.

According to the customers' requirements, gear manufacturers customize different features of gears such as material and dimensions. For example, for under water equipment, custom-made gears made of plastic or polymer are most suitable due to their corrosion resistant properties. For medial equipment, you can use custom gears with high precision.

Some important parameters you must consider before you buy a custom gear are:

1. Forces and torques acting on the gear
2. Power transmission ratio (or gear ratio)
3. Expected life of the custom gear
4. Dimensions of custom gears: pitch, module, pressure angle and diameters

The best contacts and resources to help you get it done

Buy custom spur gears from a reputable custom gear manufacturer

Spur gears are the most common type of gears for a wide range of heavy machineries and transmission systems. For special applications, go to a custom spur gear manufacturer that supplies bolts for specific applications. For example, medical devices require high precision and you need gears of precise specifications.

I recommend: American Precision Gear Company provides you custom spur gears of both fine pitch and coarse pitch. Grob, a reputable manufacturer of cold rolled gears, can provide custom spur gears with high strength, durability and superior surface finish.

Buy specialty or customized bevel gears from a custom gear manufacturer

Bevel gears provide gear motion at various angles. You can select a straight bevel gear or a spiral bevel gear depending on your requirements. For example, for under water application you can opt for custom gears made of non-metals to avoid corrosion.

I recommend: Kleiss Gears manufactures customized gears of molded polymers that are chemically resistant and lightweight with high precision. Atlas Gear is another customized bevel gear manufacturer that can supply bevel gears in different types of materials ranging from plastics to pre-hardened alloys. You can also buy a customized bevel gear at Dalton.

Purchase custom transmission gears from custom gear manufacturers

In addition to custom bevel gears and custom spur gears, you can check out for other types of custom gears according to your requirement.

I recommend: Buffalo Gear, a reputable gear manufacturer for the aerospace, military, marine and automotive industry has custom gear manufacturing capabilities of gears with diameters from 3/8-40 inches. Fairfield Manufacturing Company offers a range of custom gear products such as spur gears, bevel gears, hypoid gears and zerol gears. Milwaukee Gear Company is another custom manufacturer of precision gears and drives.
