Function and application

ZAA/ZBA electromagnetic toothed clutches transmit the torque form-fit. They are engaged at standstill. They can transmit the maximum torque over the smallest possible outer diameter from a large shaft diameter.Application fields are all machinery. 
The EZ Series are ideal for gears, machine tools, and special machinery.
The Z Series are ideal for heavy machinery and rolling mills.
