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 M series (DIN 8167) and FV series (DIN 8165) John King offer an uprated version to improve performance within more demanding applications. This comes under the Scandinavian standard SFS2380. Dimensionally as M and FV series, but with pin and bush welded to the side plates. This has the immediate and positive effect of increasing breaking strength by up to 50% as well as improving impact resistance, shock loading and general service performance.
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
