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 ?Ka must be understood as the maximum permitted enlargement of the hub distance S of the coupling. Angular misalignment ?KW - Types ZWN, ZZS, ZZW, ZWH, ZWB, ZBR, ZWS: ?KW = 1°
- Types ZWBT and ZWBG: ?KW = 0.2°
- Type ZWSE: ?KW = 0.4°
Radial misalignment ?Kr - Types ZWN, ZZS, ZZW, ZWH, ZWB, ZBR, ZWS und ZWSE: ?Kr ? VA · tan 1°
- Types ZWBT and ZWBG: ?Kr ? VA · tan 0.2°
For the tooth distance VA, see the relevant table for the subassembly.
