Compared with plastic sprockets of the same size, metal sprockets operate well and have good dimensional stability when temperature and humidity change. But compared with metal materials, plastics have many advantages in cost, design, processing and performance.
Compared with metal forming, the inherent design freedom of plastic forming ensures more efficient sprocket manufacturing. Plastic can be used to shape internal gears, gear sets, worm gears and other products, but it is difficult to use metal materials to shape them at a reasonable price. Plastic sprockets have wider application fields than metal sprockets, so they promote the development of gears to bear higher loads and transmit greater power. Plastic chain wheel is also an important material to meet the requirements of low silent operation, which requires the appearance of high-precision, new chain wheel and materials with excellent lubricity or flexibility.
Sprocket made of plastic generally do not need secondary processing, so compared with metal sprockets made of stamping parts and machine parts, the cost is reduced by 50% to 90%. Plastic sprockets are lighter and more inert than stainless steel sprockets, and can be used in environments where metal sprockets are prone to corrosion and degradation, such as the control of water meters and chemical equipment.
Compared with the metal sprocket, plastic sprocket can deflect and deform to absorb impact load, and can better disperse local load changes caused by shaft deflection and staggered teeth. The inherent lubrication characteristics of many plastics make them ideal gear materials for printers, toys and other low load operating mechanisms, excluding lubricants. In addition to operating in a dry environment, the sprocket can also be lubricated with grease or oil.

Advantages of using plastic sprockets
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.

Sprockets and Idler Wheels for 820-831-LBP831 Chain
Plastic sprockets are commonly used as an alternative to metal sprockets in power transmission and roller chain applications. Manufactured from cast oil-filled nylon, they offer a wide range of benefits over traditional metal counterparts, such as self-lubricating properties and a reduced coefficient of friction. This helps reduce wear on the plastic chain and noise levels of the application. Other benefits include better resistance to corrosion, increased impact strength, and lighter weight than metal alternatives. Split sprockets can also be supplied for applications whereby the machinery is not able to be dismantled. They are provided in two halves and can be assembled around the installation, removing the need for equipment to be taken apart.
