Torque definitions This is the reversing fatigue torque rating. The shaft will have an infinite fatigue life up to this torque level. This is the pulsating, one-way fatigue torque rating. The shaft will have infinite fatigue life up to this torque level. Here: MDS ≈ 1.5 · MDW Maximum permissible torque. If this level is exceeded, plastic deformation may occur. Bearing Note MDW , MDS and MZ are load limits for the universal joint shaft. In the case of torque values that are close to the load limit, the transmission capability of the flange connection needs to be checked, especially when...
