JOHN KING M series has become the most universally used European standard. This ISO chain is available from JOHN KING at 20 kN with 40 mm pitch through to 900 kN with 600 mm pitch. The series will therefore cater for most mechanical handling requirements encountered. This chain, although comparable to DIN 8165, is not interchangeable with other precision roller chain standards. Available with standard, large or flanged rollers it is also commonly used in its bush form notably in timber transport.
