The damping coefficient is ? = 1.1

Torsional stiffness

The dynamic torsional stiffness is load-dependent and increases in proportion to capacity utilization. The values specified in the selection table apply to a capacity utilization of 100 %. The following table shows the correction factors for different rated loads.

C_Tdyn = C_{Tdyn 100 %} · FKC

	Capacity utilization T_N / T_KN
	20 %	50 %	60 %	70 %	80 %	100 %	200 %
Correction factor FKC	0.3	0.56	0.65	0.74	0.82	1	1.9

Torsional stiffness also depends on the ambient temperature and the frequency and amplitude of the torsional vibration excitation. More precise torsional stiffness and damping parameters on request.

Permitted shaft misalignment

The permitted shaft misalignment depends on the operating speed. As the speed increases, lower shaft misalignment values are permitted. The following table shows the correction factors for different speeds.
The maximum speed for the respective coupling size must be noted!

?K_perm = ?K₁₅₀₀ · FKV

	Speed in rpm
	500	1000	1500	3000
Correction factor FKV	1.6	1.25	1.0	0.70
