Longwei Transmission manufacture custom spur gears which is based on your 2D engineering drawings, 3D models, worn parts and samples. We will make it 42crmo, 40Cr or #45 steel, or we will take your sample gear and test to determine the material and hardness. Either way, you will receive a custom spur gear meet your ends.

Spur gears are designed to run on parallel shafts to transfer motion and power; it is commonly used for motive slewing bearings.

Spur gears are the most popular form and most efficient gear device when transmitting power and uniform rotary motion from one parallel axis to another, but the cost is high. Within the limit of the center distance, the spur gear provides forward constantly speed drive. The speed can be increased or decreased by increasing or decreasing the number of teeth in the driving gear, it is called gear ratio. But they must have the same radial pitch and pressure angle.
