The load carrying capacity of designed self-centring permanent magnet based vibro-isolating support is analysed in the article. COMSOL Multiphysics modelling software was used for nu-merical simulation. Results are presented as repulsion force ver-sus support cap displacement graph as well as magnetic flux density distribution graphs. Repulsion force was also measured experimentally. It is established that differences between numeri-cally and experimentally obtained force values are only about 2–8%. It is established that maximum normal load force of the support can’t exceed 150 N. It is also established that near-zero stiffness of the support is achieved in case of approximately 70 N normal load force.
