British Standard Sprockets
Sprocket, sprocket-wheel or chain wheel are gear-like toothed cogs that mesh with chains, tracks or conveyors to provide motion and are an integral part of any power transmission mechanism.
The British Standard (BS) sprockets are engineered in accordance with ISO 9000, DIN 8187 and ISO/R606 standards and come complete with induction hardened teeth, improving the sprockets resistance to wear and increasing the sprockets working life.
