Product Details


Product Description

This Boston Gear roller chain sprocket is single strand with one set of teeth around its circumference for use with single strand chains. The teeth of the sprocket help prevent slipping and binding to avoid power loss in assemblies. It is a Type B sprocket with a hub projection encircling the bore on one side, and the bore is pre-bored to a specific diameter to fit a shaft of that size. This sprocket is made of plastic for food handling applications or where high moisture, contaminants, or corrosives are present. It meets International Organization for Standardization (ISO) 9001 for quality assurance. This single strand roller chain sprocket is suitable for use in a broad range of applications involving light to moderate loads and ongoing, high-cycle operations, including vehicle transmission systems, construction and agricultural equipment, conveyors, and factory manufacturing and assembly lines, among others.

A roller chain sprocket is a thin wheel with deep, uniformly spaced teeth ringing its circumference. The distance from the peak of one tooth to the next is called the pitch, and is commonly measured in 1/8-inch increments. The sprocket transfers power and motion by a roller chain that is threaded over the teeth of the sprocket. The alignment of the chain with the sprocket's pitch prevents the chain from slipping so that no power is lost. In the center of the sprocket is the bore (hole) for sliding the sprocket onto a shaft, and a bushing or bearing is often fitted to the sprocket’s hub to custom-fit the sprocket onto a shaft to hold it firmly in place. A hub is a protruding, raised lip encircling the bore of the sprocket. Sprockets with hubs on both sides are Type C, sprockets with hubs on one side are Type B, and sprockets with no hubs are Type A sprockets. For applications requiring sprockets to be swapped onto shafts of different diameters, a sprocket with a bore large enough to fit all shafts can be used, with the gap between the bore and shaft closed with a bushing or bearing. Roller chain sprockets are used in a broad range of applications where the drive power of an engine needs to be transferred into motion, such as in motor vehicles, conveyors, escalators, agricultural, forestry and mining equipment, aeronautics, robotics and space exploration, among others.

Boston Gear manufactures a variety of gear drives, variable speed drives, clutches, and the components that comprise these systems including sprockets and bearings. Their manufacturing designs, production, and inspection meet International Organization for Standardization (ISO) standards for quality assurance. The company, founded in 1877, is headquartered in Charlotte, NC.
