Multi-Beam Couplings

These general purpose, multi-beam couplings will readily accommodate any combination of axial motion and angular & parallel misalignment but should be used with caution if low bearing loads are desirable. The three start helical-cut design provides higher torque capability and greatly reduced wind-up when compared to single beam couplings. The 6 beam version provides greater misalignment capability but reduced torque accuracy when compared to the 3 beam version.
