Chain drive is the most common power transmission device used in machines of industry and transportation. Without it we would still be using gears and shafts.

Though Hans Renold is credited with inventing the roller chain in 1880, sketches by Leonardo da Vinci in the 16th century show a chain with a roller bearing.

Hans Renold Limited was formed as a private limited company in 1903. It merged with The Coventry Chain Company Limited and was registered as a public limited company named Renold and Coventry Chain Company Limited in 1930. It was renamed Renold Ltd. in 1967, and later became Renold PLC. Nowadays the company still bears his name.

Renolds still produces quality motorcycle drive chain in half a dozen countries.
