Bob Wellsbury, MD, explains: “Our standard roller chain products are extremely popular and we have developed a strong customer base of distributors and OEMs in the UK over the last seven years. To help our customers market these products more effectively, we have decided to group them within ‘Standard’ and ‘Standard Plus’ brands.”

“All of our roller chain products are made to the highest standards irrespective of which of the new brands customers choose. There are, however, some application advantages versus pricing benefits associated with each which we felt could be made clearer.”

Donghua’s Standard Roller chain products incorporate a split bush and solid roller, whereas its Standard Plus Roller chain uses a solid bush and solid roller which improves wear life and reduces elongation. Other variants are also available such as Chromised pin chains. Both Standard and Standard Plus chains are available in ANSI and BS.
