Traditional sprocket manufacturing process
metal forming – This process usually involves the use of a die to form the circumferential teeth. Powder Processing – The sprockets in this method are made from metal powder. This process has 3 steps: powder mixing – pulverization; die compaction; and sintering.

What material are the sprockets made of?

Sprocket material

cast iron The most common and economical flat wire belt sprocket material, they are precision cast from high quality iron. Other diameters are available by special order. All plastic sprockets are fully machined to meet USDA and FDA food contact guidelines.

What are motorcycle sprockets made of?

The two most commonly used materials for motorcycle sprockets are aluminum and steel. While steel is the material of choice for many OEM sprockets, aluminum has some properties that make it more attractive to certain types of performance-oriented riders, track fans and racers.

How are sprockets calculated?

Calculate the sprocket ratio

The sprocket ratio is simple The number of teeth on the driving sprocket (T1) divided by the number of teeth on the driven sprocket (T2). If the front sprocket on the bike has 20 teeth and the rear has 80 teeth, the sprocket ratio is 20/80 = 1/4 = 1:4 or simply 4.
