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.
Type A – Bush type
Type B – Small roller
Type C – Large roller
Type D – Flange roller

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
