What is sprocket (Sprockets Category)?
Basically, a sprocket(Category) is a groove wheel with teeth that mesh with links to transfer motion between one wheel and another. Wheels are apply to machinery to convey heavy loads.
- They come in different designs and sizes and we can use a variety of materials to produce.
- They are available in single strand, double strand, and triple strand.
- We can make a single piece or a hub. They are usually flat or curvy.
The most common type of sprocket is the roller chain sprocket. This type is typically apply to transmission equipment. It operates along chains apply by rollers that are interconnecte by pins. Each pin forms a gap which allows the teeth of the sprocket to move. We often manufacture the sprockets from cast iron, mild steel, or stainless steel.
Someone design sprockets for multi-strand chains which drive higher torque. These sprockets’ applications: in power transmission equipment, agriculture equipment, and bicycles. They are also apply to conveyor systems.
These sprockets are usually bolt-on back together to make installation easier. The sprockets’ typically materials: 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.

FU Scraper Conveyor Cast Sprockets
The chain sprocket of scraper has high strength, wear resistance, can withstand pulse combination and impact load, and has certain toughness; The design of tooth size parameters is accurate, the processing precision is high, and the chain is well matched.
At present, the number of sprocket teeth is generally 6-8.
80 Chain Sprockets
80 Chain Sprockets are manufactured in accordance with ANSI B29.1 Standards and are made for 1″ pitch 80 and heavy-duty 80H roller chains. Being manufactured to The American National Standards Institutes dimensions means that these sprockets directly interchange with other manufacturers. Up to 30-teeth, our 80 sprockets feature hardened teeth for a dynamic performance factor increase and increased sprocket longevity.
120 Roller Chain Sprockets
120 Roller Chain Sprockets (120 sprockets) are manufactured for 1.5″ pitch ANSI 120 Roller Chains and are available in a wide array of configurations and tooth counts. Our 120 roller chain sprockets are supplied with hardened teeth as a standard for tooth counts 30 and below, are made from a high-strength steel, and are typically black oxided for corrosion resistance. We also supply a slew of custom 120 chain sprockets and can usually have them done within a day or two.
Split Sprockets and Injection Idler Wheels
Our plastic sprockets have a much greater tooth deflection than a standard steel sprocket. This means that several teeth will bear the load of the roller chain. With several teeth in contact, the sprocket’s load capacity will match approximately the full working load of the chain. Some of the main benefits of using a plastic chain sprocket are that they run quieter and produce a much better wear life on the roller chain. These sprockets are also highly anti-corrosive, extremely lightweight, and have high impact resistance.
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 in order 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 |
