Chain of ideas

Looks at a new environmentally‐friendly roller chain. Describes the make‐up and qualities of the three models EFC1, EFC2 and EFC3 and examines some of their common features. The chains do not need lubrication in use and they are relatively small and light. The absence of lubrication means dirt and debris are not attracted to the chain. Concludes that the development of these chains is part of a larger project to develop an environmentally‐friendly transmission system primarily for bicycles but their eventual application could be much wider including use in the food and pharmaceutical industries, office equipment and washing machines.
