Technical data
Power ratings
In the case of type ZWTR, the rated torques which deviate from
the above are specified in the dimension table.
The stated torsional stiffness „ZW“ applies to coupling types
ZWN and ZWNV.
Torsional stiffness of the remaining types on request.
The axial misalignment
Δ

must be understood as the maxi-
mum permitted enlargement of the hub distance S of the cou-
pling.
The axial misalignment for the types ZWBT, ZWBG and ZWNV is
