What is a Sprocket?
Basically, a sprocket is a grooved wheel with teeth that mesh with links to transfer motion between one wheel and another. These wheels are used in machinery to convey heavy loads.
They come in different designs and sizes and can be fabricated from a variety of materials. They are available in single strand, double strand, and triple strand. They can also be made of a single piece or a hub. They are usually flat or curved.
The most common type of sprocket is the roller chain sprocket. This type is typically found in transmission equipment. It operates along chains formed by rollers that are interconnected by pins. Each pin forms a gap which allows the teeth of the sprocket to move. These sprockets are often manufactured from cast iron, mild steel, or stainless steel.
Some sprockets are designed for multi-strand chains which drive higher torque. These sprockets can be found in power transmission equipment, agriculture equipment, and bicycles. They are also used in conveyor systems.
These sprockets are usually bolted back together to make installation easier. They are typically made from cast iron, graded stainless steel, or mild steel. The chain sprockets are characterized by high tensile strength and high wear resistance.
Some sprockets have a hub that helps to keep the sprockets from being overhung on the equipment. They are also available in a variety of tooth counts and diameters.
The chain sprockets are available in a variety of sizes, including smaller ones for ash-handling applications. They can also be installed by slackening the chain. Custom-made sprockets are also available a Powertrans, one of the experienced China sprocket suppliers and manufacturers.

How to Select Sprocket Material?
The sprocket material shall ensure that the teeth have sufficient strength and wear resistance, so the sprocket tooth surface is generally heat treated to achieve a certain hardness
The following table shows the heat treatment methods and applicable conditions of different materials.
Materials | Heat treatment | Tooth surface hardness | Applicable conditions: |
15#, 20# | Carburizing, quenching, tempering | 50-60 HRC | Z ≤ 25 sprocket with impact load |
35# | normalizing | 160-200HBS | Z > sprocket |
45#, 50#, ZG310-570 | quenching, tempering | 40-45HRC | Sprocket wheel without severe impact, vibration and wear resistance |
15Cr, 20Cr | Carburizing, quenching, tempering | 50-60HRC | High power drive sprocket with Z < 25 |
40Cr, 35SiMn, 35CrMo | quenching, tempering | 40-50HRC | Important sprocket requiring high strength and wear resistance |
A3, A5 | welding annealing | 140HBS | Large sprocket with medium-low speed and medium power |
≥HT200 Grey cast iron | quenching, tempering | 260-280HBS | Sprocket with Z > 50 |
