to a max.+160)
Perm. temperature range (°C)
Continuous Max. t emperaturetemperature short time
Typicalapplications
I.C.-engines, for high dynamic load,high air moisture/resistant
to hydrolysis
Drives with higher loads, small twisting angles -torsionally
rigid, high ambient temperatures
Small twisting angles and high torsion spring stiffness,high
ambient temperature, good resistance to chemicals
Small twisting angles and high torsion spring stiffness,very
