#25 Plastic Sprockets

#25 Plastic Sprockets

We are the premier supplier of plastic power transmission components. We have plastic sprockets available in ANSI sized #25 - #80 and in a UHMW, Nylatron, or Nylon material. Other materials such as Repro and Acetal can be used as well, and we can produce the plastic metric, double pitch, duplex, engineer class, and custom-designed sprockets. Some of the main benefits of using a plastic roller 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, have high impact resistance, and are FDA-approved.Our plastic sprockets have a much greater tooth deflection than a standard steel sprocket does. This means that several teeth will bear the load of the roller chain. With several teeth in contact, this means that the load capacity of the sprocket will match approximately to the full working load of the chain.

Plastic Sprockets Material

The material that is selected to make plastic sprockets can vary depending on the intended application. Most often, acetal is used, which offers a high impact strength as well as good abrasion resistance. It is also a good choice for close-tolerance applications. Nylon is another popular type of plastic. Oil-filled nylon is a great alternative, as it has a low coefficient of friction and excellent abrasion resistance. Other options include PTFE (Teflon), polypropylene and urethane.

Applications of Plastic Sprockets

Applications for plastic sprockets include dusty or gritty environments, food applications requiring frequent wash-downs, and areas where a quieter chain drive is needed.

The Benefits of Plastic Chain and Sprocket

Plastic chain and sprockets are used in many industries and applications. They are made of durable polymer materials that offer wear and corrosion resistance as well as noise reduction benefits. These components are typically utilized in industries such as food and beverage, packaging and waste water treatment. Some plastic chains and sprockets are USDA/FDA approved. This allows manufacturers to meet the specifications of their customers, and helps reduce procurement costs.One of the best features of plastic chain and sprockets is that they are relatively lightweight. This allows them to be mounted on a wide variety of applications. They offer less weight and a lower coefficient of friction compared to metal sprockets. Another benefit is that they are non-magnetic. In addition, they are self-lubricating, meaning that there is no need to add lubrication to the sprocket. Although they require some maintenance, their durability makes them a cost-effective option.When using chains and sprockets in dusty or dirty conditions, it may be a good idea to choose a plastic option. This is especially important if there is potential for contamination. Because they are abrasion resistant, plastics can prevent unsanitary conditions caused by toxic lubricants. Additionally, they are also non-conductive, making them ideal for power transmission applications. Plastic chains and sprockets can be designed with additives for self-lubrication. This allows them to perform more efficiently, without requiring lubrication. A self-lubricating sprocket can reduce friction and increase wear resistance. Choosing a plastic chain and sprocket can help reduce the cost of running equipment in a variety of industries. However, these can be difficult to maintain, as they require periodic cleaning. When considering the various types of materials, it's important to consider how much load is being applied to the sprocket. The load capacity should match the amount of weight being carried. Metal inserts can be used to spread the weight over a larger area, which improves the sprocket's load capacity. However, they can be expensive. Instead, a metal roller bearing can be fitted to the hub of a plastic sprocket, increasing its operating speed and load capacity.

Plastic Sprocket Types

The standard styles of a plastic roller chain sprocket are A-plate style meaning that there is no hub on either side of the sprocket, B-hub style which has a hub on one side; and C-hub style, which has a hub on two sides.Standard bore styles for plastic sprockets are a stock bore, which is a plain unfinished hole in the center of the sprockets. Finished bore, which is a certain bore size that includes a key-way and two stainless steel set screws. Idler sprocket, which we can supply bearing idler plastic sprockets, bronze bore idler sprockets or plain bore style, just advise the shaft size and we supply the bore with proper clearance to idle on the shaft.
