Ils permettent d\u2019accompagner les mouvements oscillatoires et les d\u00e9salignements angulaires, contribuant \u00e0 la pr\u00e9cision et \u00e0 la durabilit\u00e9 de l\u2019application, m\u00eame lors de la transmission de charges de traction et de compression.<\/p>

La gamme MBI comprend diff\u00e9rentes configurations, s\u00e9lectionn\u00e9es en fonction du r\u00e9gime de charge, de l\u2019environnement de travail et des besoins de maintenance.
