Grid couplings from jbj Techniques reduce vibration by as much as 30%, and cushion shock loads to safeguard your driving and driven equipment.

The flexible nature of the spring-like grid absorbs impact energy by spreading it out over time, thus reducing the magnitude of the peak loads. This is possible because of the progressive contact that occurs between the curved profile of the hub teeth and the flexible grid. Therefore, as the load increases, more of the tooth comes into contact with the grid, thus supplying superior protection and supreme performance.

jbj Techniques have a coupling for most mechanical power transmission applications and the technical knowledge and machining capabilities to create custom couplings for the more unusual applications. View the full range at
