The pre-load system uses a double nut system in which two ball screw nuts are combined to provide pre-load by means of a spacer, eliminating backlash. The nut dimensions comply with the ISO standard (ISO 3408). This type has improved axial rigidity compared to the other ball screw. SDAN-VX type is a full ball type.

Model EPB-V

A ball screw with newly developed circulation components that give it an ideal ball circulation structure. (Maximum DN value: 160,000)The nut dimensions conform to DIN standards (DIN69051). Furthermore, the use of the newly developed thin film seal reduces the length of the nut, achieving a more compact design for the device. This is the full-ball type version of the Model SDA-V. (Maximum DN value: 130,000)
