A sprocket or sprocket-wheel is a profiled wheel with teeth or cogs that mesh with a chain, track or other perforated or indented material. The name “sprocket” applies generally to any wheel upon which are radial projections that engage a chain passing over it. It is distinguished from a gear in that sprockets are never meshed together directly, and differs from a pulley in that sprockets have teeth and pulleys are smooth.
We have many sizes of sprockets in British Standard design in stock. Please email us with your requirements. Special sprockets with non standard teeth pitch can be manufactured as per drawings and specifications.
