KWD ZAKU-N Gear Couplings
KWD ZAKU-N gear couplings are all-metal torsionally rigid gear couplings enabling the transmission of the highest torques with small installation dimensions.
Shaft Coupling Description
KWD ZAKU-N gear couplings have special gearing, which allows only a small backlash and allows smooth running over the entire speed and torque range. Grease lubrication ensures low maintenance while allowing for relatively large shaft misalignment.
Couplings are able to compensate for radial, angular and axial misalignments.
Shaft Coupling Construction

- Two-piece outer housing with sleeve and internal gearing
- Left hub with external gearing
- Right hub with external gearing
- Fit bolt
- O-ring
Typical Applications
ZAKU-N gear couplings are used in the steel, rubber and paper industries, as well as in cranes, pumps, compressors or conveyors.
ZAKU-N gear couplings are designed for the transmission of the highest torques in all industries. They are used mainly in the drives of conveyor systems, rolling mills, mixers, cranes and other highly stressed drives in steel mills, in the paper, chemical and rubber industries.
The couplings are available in various series and designs.
