Expansion of the robust SP3 metal bellows coupling with external clamping ring
The range of SP3 metal bellows couplings has been expanded to include new models. The welded design is capable of transferring torques of between 800 and 10,000 Nm. Previous models of the SP3 with external clamping ring were available for torques of between 60 and 500 Nm.
The coupling can be installed via the external clamp taper socket without axial or radial forces in the bellows body. As a result, the hubs and bellows body are barely deformed and the clamp taper socket remains unaffected in terms of its safety function.
The special metal bellows coupling is extremely robust thanks to its high-tensile steel construction. This makes it a reliable partner for applications involving high temperatures.
