The OMT ND86A motor half coupling is designed for installation on an electric motor shaft and is used in assembling pump-motor units (pump + motor). It fits a motor shaft with a 28 mm diameter and 8 mm keyway. Used together with the R-82 elastic spider and ND86P2 (for group 2 pumps) or ND86P3U (for group 3 pumps) pump half couplings. Ensures precise shaft alignment and reliable torque transmission. OMT half couplings are designed to handle high torque and compensate for angular, radial, and axial misalignments. Compatible with standard-flange electric motors up to 315 kW and most common pump types.
