• Double Nut Ball Screw assembles two inner-circulate nuts together, therefore reduces the backlash of ball screw. The stability is then enhanced and the accuracy is up to 5. This design is especially good for CNC machine centers

• No stick-slip effect, low friction, low operation noise, heats up less, reduce driving power required, and make service life longer

• Double nut ball screw model includes DFU1604, DFU1605, DFU2005, DFU2505, DFU2510, DFU3205, DFU3210, DFU4005, DFU4010, DFU5010, DFU6310, DFU8010; Ball screw nut, nut housing, coupling, ball screw support BK, BF, EK, EF, FK, FF and end machining service are available, please let us know

Introduction and Application: Double ball nut designs produce preload in one of two ways: through tension between two single nuts, or through an offset in the lead of a single nut. 1. The first method uses a spring or a spacer to create tension between two nuts that are mechanically coupled. During machining of the ball nut raceways, an offset is created in the lead, approximately halfway down the length of the nut body. This lead offset creates preload within the ball nut. Because there are no spacers or springs required, the lead offset method is more compact than a double nut design, but it reduces load capacity. With greater complexity and higher cost, double nut designs are typically used when high preload (7 percent or greater) is required.
