M Series Chains

John King M series has become the most universally encountered European standard of Engineering class chain. It is available in standard bush series, with small “gearing” roller and large carrier roller with or without flange. The fundamental difference between the John King product is that in employing better materials and heat treatment characteristics we achieve higher strength and better wear performance. John Kings approach is always to seek improvements in specifications and or constructions that, where appropriate will enhance product performance.

Special attention should be applied to options in construction.

John King EXCEL standard SFS2380

For both M (Din8167) John King offer an uprated version to improve performance within more demanding applications. This comes under the Scandinavian standard SFS2380. Dimensionally as M, but with pin and bush welded to the side plates. This had the immediate and positive effect of increasing breaking strength (up to 50%) as well as improving impact resistance, shock loading and general service performance. This up-rated version can also be offered on FV chains .

Sprockets for Metric Chains

Sprockets with split construction are preferred for ease of replacement (Type TS). The tooth form incorporates John Kings unique profile allowing for increased gap angle and bottom line clearance to prevent material packing and reduced wear rate during operation.

Sprockets of segmental construction include bolt on tooth rings for obvious benefit in replacement (Type CS). The tooth form incorporates John Kings unique profile allowing for increased gap angle and bottom line clearance to prevent material packing and reduced wear rate during operation.

Material options: 

  • BS970 080M40 carbon steel suitable for surface hardening to 550Bnh at a minimum effective depth of 2.5 mm 
  • BS EN 10025 S355J2 high strength steel 
  • Other options available on request.
