Coupling is a core component that transmits power and motion
from the driving shaft to the driven part while absorbing misalignment
and any possible factors that could reduce efficiency of machines
(e.g. vibration, noise, electric current, etc.)

REACH (Registration, Evaluation, Authorization and Restriction of Chemicals)

  • REACH is a regulation of the European Union, adopted to improve the protection of human health and the environment from the risks that can be posed by chemicals, while enhancing the competitiveness of the EU chemicals industry. It also promotes alternative methods for the hazard assessment of substances in order to reduce the number of tests on animals.
  • Registration is the process of identifying substances that are produced or used in the EU. It applies to substances directly as well as substances in mixtures and in articles (parts). For substances in articles, a registration must be submitted if: The substance is produced or imported at a weight greater than 1 ton per year AND has a mixture or concentration greater than 0.1% by weight AND meets requirements of Article 57.
  • Sung-il Machinery has completed the SVHC evaluation on all the coupling products based on 2012/12 standard. If it is requested to conduct any additional SVHC evaluation, please feel free to contact Sung-il Customer Service team.
