Starting immediately, the WF planetary gears are available in three sizes with drive torques from 1,000 Nm to 4,000 Nm. Special features of the gears are their exceptional reliability and smooth running properties.

As with all other WF gears, the new WF planetary gears also feature a modular design principle. Due to the robust bearings for the transfer of high radial and axial loads, the planetary gears are designed to withstand high dynamic requirements.
The three sizes NRG 10, 20 and 40 enable transmission ratios from 3.45/1 to 3.657.3/1 (1-stage to 4-stage).
WF planetary gears are available with different input and output types, base or flange mounting, a free input shaft or for IEC motor mounting.
