5 Denitions and Abbreviations 5.1 Lengths Universal joint shaft with length compensation Universal joint shaft without length compensation lB : Operating length (Please indicate with order.) lB : Operating length, corresponds to the universal joint shaft length l (Please indicate with order.) lz : Shortest length of the universal joint shaft (fully collapsed) lv : Available length compensation The distance between the driving and the driven machines, together with any length changes during operation, determines the operating length: Optimal operating length: Maximum permissible operating...

Reversing fatigue torque rating. The shaft will have an infinite fatigue life up to this torque level. Pulsating one-way fatigue torque rating. The shaft will have an infinite fatigue life up to this torque level. Where: MDS ≈ 1.5 · MDW Maximum permissible torque. If this level is exceeded, plastic deformation may occur. Values available on request. Permissible torque for rarely occurring peak loads. Bearing races may suffer plastic deformation at torque levels in excess of MZ. This can lead to a reduced bearing life. Load rating for bearings - when used with operating values, enables...

The S Series is the basic version of universal joint shaft and is designed for mid-range drives. The connection flanges are designed as friction flanges. Dimensions in mm. Longer lv available on request

Length compensation Steel on steel, no profile protection Steel on steel, with profile protection Rilsan® coating on steel with profile protection PTFE coating on steel, with profile protection Shorter lZ available on request.
