Handling Ball Screw Jacks
MANUAL AND MOTORIZED OPERATION
The K series only presents one ratio for all three sizes: an exact 1/5. This allows a great deal of precision in the couplings. All the K series can be manually or motor operated. As a standard production, for the IEC unified motors, it is possible to connect them directly to screw jacks. Special flanges can be made for hydraulic motors, pneumatic motors, brushless motors, as well as for direct current motors, permanent magnet motors, stepper motors and other special motors. In the case where it is not possible to motorize a screw jack directly, a connection by means of an housing and a joint can be foreseen. The power curves determine, in case of unit service factors and for every single screw jack, the moving power and the input torque according to the size and the requested output torque.
ROTATION DIRECTIONS
In standard conditions UNIMEC supplies K series screw jacks equipped with right-handed worm screw, to which correspond the movements illustrated in the drawings below.
