John King welded steel chains have become North Americas preferred choice in many materials handling applications. The simple and robust construction offers a superior method of conveying most materials. These chains employ an offset side plate and circumferentially welded bush. The pin is a high interference fit into the plate retained with a heavy hot rivet or cotter. The standard KING specification is uprated over the industry standard with the proven IBR designation. This incorporates standard through hardening, but with additional surface induction hardening of both the bush and pin. The end result is a chain offering maximum toughness and high abrasion resistance for optimum performance in high duty applications.

Add IBR for fully heat treated parts plus induction hardened barrels and rivets.
John King offer a series of welded steel chains specifically designed for high impact and abrasing resistance as encountered in timber decks and high duty timber applications. The chain includes fully heat treated chain parts with the addition of induction hardened barrels and rivets. Chains are primarily riveted construction with extra large formed rivet head to ensure maximum integrity.

Add IBR or fully heat treated parts plus induction hardened barrels and rivets.
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.
