John King offer a unique range of welded steel chains dimensionally equivalent to M Series bush chains according to DIN8167. The chain offers all the benefits of the “offset” sidebar welded construction and can be offered as a direct replecement in existing conveyors and operate on same sprockets. This allows the user a unique opportunity to improve reliability and service life without major alteration.

Key Features:

  • Direct replacement with Metric standard DIN 8167,
  • Increased ultimate tensile strength of up to 65% as compared to standard M series chain,
  • Welded bush for increased shock resistance,
  • Best specification with all parts through hardened and surface induction hardening on pins and bushes,
  • Crank link design as US standard ISO DP6972. A beneficial construction with maintenance advantages,
  • Option to induction harden sliding surfaces,
  • Grease lubrication can be included if required,
  • Ease of maintenance with an option to remove one offset link not two as with straight sidebar chain.
