Ball Screw Jacks Design Considerations

Standard Flange Orientation

Standard flange orientation varies with the number of holes in the flange. Unless otherwise specified, a factory-assembled flange will be oriented on the nut as shown. (See Image 1 in Figure 1 Below)

Proper Ball Nut Orientation

When a ball screw assembly is used in an orientation other than vertical, it is important to orient the return tubes to optimize ball nut operation. (See Image 2 in Figure 1 Below)
