ZF Expands its 2K Transmission Series for Machine Tools by two Variants

  • Two new sizes of the 2K precision transmissions
  • High torques at low rotational speeds

ZF Friedrichshafen AG continuously expands the production line for two-speed manual transmissions for machine tools. With two new sizes of the 2K precision transmissions, all common power, torque, and motor classes of industrial machine drives can now be covered. This way, the performance range of machine tools can be used in an optimal and energy-efficient way.

ZF Expands its 2K Transmission Series for Machine Tools by two Variants

The new Duoplan 2K 450 and 2K 600 two-speed manual transmissions now complete ZF's product range as latest innovations. The transmissions, that can be delivered as of now, are designed for nominal input torques of 450 or 600 Nm and thus complete the 2K series which already covers torques up to 300 and over 800 Nm.

ZF now offers more than ten different transmission variants for several applications and installation positions with the expanded product range. With their help, motors with installation dimensions of 100 to 280 millimeters axle height can be operated; the range of the transferred power is between 19 and 120 kW, the range of the nominal input torques is between 120 and 1200 Nm.

For mechanical engineering companies, this extensive range of transmissions offers the advantage to further increase their efficiency and their cost-effectiveness, because an optimally adjusted motor/transmission unit also reduces energy consumption.

In addition, there are the proven advantages of the shiftable two-speed transmission: If hard materials are to be machined, the ZF Duoplan 2K transmissions transfer high torques at low rotational speeds. If soft materials must be processed, the ZF machine drives supply high speeds in the upper speed range.
