What is BS 6613 – resilient shaft couplings sourcing guide about? 
Resilient shaft couplings are generally introduced into transmission systems to provide a degree of protection from shock or to tune out vibrations.
BS 6613 is an International Standard that specifies the information to be supplied by users and manufacturers of resilient shaft couplings in order to facilitate communication and understanding between users and manufacturers.
Note 1: BS 6613 does not apply to:
- Rigid flange or sleeve couplings
- Torsion-ally stiff couplings for alignment purposes, such as toothed or diaphragm couplings.
- All types of slip couplings
Note 2: BS 6613 does not give dimensional requirements for either shafts or couplings.
Who is BS 6613 – resilient shaft couplings sourcing guide for?

Why should you use BS 6613 – resilient shaft couplings sourcing guide?
When sourcing resilient shaft couplings, clear communication with the manufacturer or vendor affects whether the couplings meet your needs or not. BS 6613 functions as your handy communication guide when sourcing or supplying resilient shaft couplings.
The introduction of a resilient shaft coupling into a transmission system affects its torsional, axial, rotational and alignment characteristics. BS 6613 recommends that the choice of a coupling for complex transmission systems be based upon a comprehensive analysis of the complete system.
Some couplings can also accommodate misalignment. However, misalignment is considered in BS 6613 only in so far as it affects the operation of the couplings.
BS 6613 guides you with information to be supplied by the user as well as information to be supplied by manufacturers. BS 6613 guidelines help you to facilitate clear communication between users and manufacturers of resilient shaft couplings.
