Sprockets and Idler Wheels for 812/815/881M/820/ 802/805/881BEVEL/881TAB 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.Plastic Sprocket TypesThe standard styles of a plastic roller chain sprocket are A-plate style, meaning 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, a plain unfinished hole in the center of the sprockets. The finished bore is a specific 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, advise the shaft size, and we provide the bore with proper clearance to idle on the shaft.
