Chain Sprockets and Gears
Sprockets and gears are grooved wheels that operate within a machine, but their functions are different. Gears are generally toothed wheels that connect with the teeth on another gear to transmit movement. Sprockets use their teeth to “bite” into or interact with one or more flexible components, like a chain or conveyor belt. At TSE, we can fabricate a wide variety of these custom sprockets, gear, or conveyor components to meet your specific application needs.
Our custom-made, high-performance UHMW replacement parts are lightweight and won’t rust or corrode. These change parts also lessen noise pollution and can reduce the need for lubricants, and in some cases eliminate them.
Sprocket & Gear Arrangement
We can make several types of engineered plastic sprockets:
Wire Belt | Roller Chain | Wastewater | Mill
Our expertise also covers:
Keyways | Setscrews | A, B, and C Hubs
Considerations
Below are some aspects to consider when you are determining your sprocket or gear. Our Sprocket and Gear Buyers Guide can help.
Chain Type | Set Screws | Number of Teeth | Hub Type
Bore Type & Size | Split or One-Piece | Key Way | Hub Diameter
Nominal Width | Outside Diameter | Length Through Bore (LTB)
Pitch and Pitch Diameter

Material Choices
Although Sprockets and Gears can be machined out of a number of materials like Nylon, Teflon, and Acetal, the most popular is Duro-Glide® UHMW-PE.
