COMMUNIQUÉ  ON  
TS ISO 529 1 BELT DRIVE – GRO OVED PULLEYS FOR CLASSICAL COMBİNED 
V BELTS  - GROOVE PROFILE  AJ, BJ, CJ AND DJ  (EFFECTIVE SYSTEM)  FOR 
THE ASSEMBLIES  STANDARD  
(COMMUNIQU É NO: MSG – MS – 2018  / ) 
 
 
  
Purpose  
ARTICLE 1  – (1) The purpose of this Communiqué is to identify issues related to the 
implementation of application  of TS ISO 5291 (August  2015) ‘‘Belt Drive  – Grooved Pulleys 
for Classical Combined  V-Belts  - Groove Profile  AJ, BJ, CJ and DJ  (effective system) ’’ 
standard.  
 
Scope  
ARTICLE 2  – (1) This standard covers the main characteristics of grooved  pulleys 
(groove profile  AJ, BJ, CJ and DJ) designed for combined  classical V-belts intended for 
industrial power transmission drive systems.  
(2) The effective width of a groove is considered as the main dimension of 
standardization for grooves that are evaluated as a whole and corresponding combined  V 
belts . 
(3) The pitch  line position can only be approximated . The approximate pitch diameter 
of a pulley  can be calculated by the following equation.  
dp = de - 2be
