UTMⅢ/UTMⅡ/UTMV are designed to withstand any disturbing stress induced by radial or thrust forces. However, radial/thrust overloads will not only result in measurement error but also heating-up of the bearings and/or irreversible distortion or fracture of UTMⅢ/UTMⅡ/UTMV. Couplings accurately connects two individual shafts. Recommended couplings are indicated in the table below. Consult one of our sales representatives for couplings for the UTMⅡ-10000Nm and key groove option.
