| | | The UNIVERSAL worm gear unit Type SI are available in module form or as assembled units (addition cost) Assembled units are ordered with the above mentioned type description. The total gear ratio and mounting position (see page 8) must also be specified. The order/quotation form (page 70) can be used here. Example,double wormgearmotor withtorque arm: SK 1SI 50/31 D - IEC63 - 63S/4, Total gear ratio iges=600 Mounting Position DA/I 270, U1, KK1/III The worm gear unit module carries the name plate. The printed description types here refer to each worm gear unit module. Assembled units receive a name plate that refers to the entire unit. | | The modules are ordered using the 8-digit order number in the catalogue, which does not specifythe mounting position and the gear ratio. The order/inquiryform (page 70) can be used. Example, double worm gear motor with torque arm: Order no. 60591300 (general design SK 1SI 50, isch =30) 60593900 (torque arm module) 60494100 (double gear unit) 60391200 (general design SK 1SI 31, isch =20) 60395010 (IEC standard motor mount module) 31010020 (IEC AC motor) | | |
