Series 52Download PDFCatalogue No.:UT-52 | Revision 00

Series 52 are high speed as well as high torque capacity couplings. The costruction is in spacer design with central spacer member being removable without having to shift either driving or driven machine. The discs are loose ( not unitized) . The couplings have comparatively low moment of Inertia & high torsional stiffness.
