Explanations:
X Last number:
1 for operation in clockwise (right-hand) direction
2 for operation in counter-clockwise (left-hand) direction
1) Min. bend radius: The bend radius cannot be smaller than this value.
2) Torsional deflection: Torsional deflection angle over 1 m shaft with torque of 10 Ncm.
3) Breaking torque: At this load the shaft will break.
4) Max. torque: Values applicable for straight shaft at speeds of 20% of maximum rated speed.
