Synchronous Pulley

H Synchronous Pulley

The synchronous pulley consists of a closed ring tape with equal spacing teeth on the inner perimeter surface and the corresponding belt pulley. Synchronous pulley generally refers to steel, aluminum alloy, cast iron, brass, and other manufactured materials. They are widely used in automobiles, textiles, printing and packaging equipment, sewing equipment, office equipment, laser engraving equipment, tobacco, financial tools, stage lighting, communications food machinery, medical machinery, steel machinery, petrochemicals, instrumentation, a variety of precision machines tools and other fields.

As one of the synchronous pulley manufacturers, suppliers, and exporters of mechanical products, We offer synchronous pulley and many other products. Please get in touch with us for details.
