Custom Spur Gears

Click here to build spur gear CAD models.™ manufactures custom spur gears based on your 2D drawings,3D models, or old, worn out parts or samples. We will manufacture them out of the material YOU specify or we will take your sample gear and have it tested to determine the material and hardness. Either way you will recieve a custom spur gear manufactured to your custom needs.™ Spur Gears are designed to operate on parallel shafts to transmit motion and power.™ offers the largest selection in industry today.

Spur Gears are the most popular form and the most efficient type of gearing for the cost when transmitting power and uniform rotary motion from one parallel shaft to another. Within the limitations of center distance, spur gears provide a positive, constant speed drive, the speed of which may be increased or decreased by increasing or decreasing the number of teeth in the driving gear.

Spur Gears may be operated in a “gear-train” of two or more gears but they must all be of the same diametral pitch and pressure angle. Gears with 14-1/2° pressure angle will not operate with those cut to 20° pressure angle.™ SPUR GEARS are available in eight materials: STEEL, HARDENED TEETH, CAST IRON, BRONZE, STAINLESS STEEL, ALUMINUM, NYLON, NON-METALLIC PHENOLIC. Gears made of custom materials to customer specifications can be promptly furnished.

Pitch line velocity of metallic gears should not exceed 1200 feet per minute. Where noise is a factor, but higher speeds cannot be avoided it is recommended that a nylon or non-metallic gear be used and operated up to speeds of 2400 feet per minute preventing much of the noise and vibration caused by metal to metal contact.

All critical surfaces of™ SPUR GEARS are precision machined to close tolerances. Change Gears, Pinion Wire, Stem Pinions, Internal Gears and Rack are all spur gears of various types able to operate together since each has the same straight involute tooth form.
