On request

For further binding technical specifications and configuring aid (e.g. lubrication, temperature rise and typical applications), please refer to the latest catalog supplied by ZF (Zahnradfabrik Friedrichshafen). The permissible characteristics of the motor and gearbox are a governing factor in the design of the complete drive unit (motor and gearbox).With 1PH7167-2NB motors, for example, the rated torque must be reduced to 300 Nm (221 lb?-ft). With motors of SH 132, please note that the maximum permissible speed of the 2K 250 gearbox for splash lubrication is 6300 rpm.

1) Higher drive speeds are allowed with oil-cooled gearboxes and for gear ratios I = 1 in some instances (refer to the ZF Catalog).
2) Special versions, such as gearboxes with different torsional backlash, or other gear ratios (I = 3.17 or I = 5.5), are available on request.
3) Preconditions: DE shaft extension with fitted key and full-key balancing.
4) Preconditions: DE shaft extension with fitted key and full-key balancing. Bearing version for coupling output. Shaft and flange accuracy tolerance R. DE flange with shaft sealing ring.
