with double ball screw nut and with standard end machining for BK/BF15. The lead time is 7-10 Business Days except for for Chinese National Day holiday and Spring Festival.
WARRANTY: Within 3 months receiving the ball screw, if there is any problem except for damage caused by man-made or improper operation, with the premise of choosing the proper product model and ensuring the working environment ventilatedly and tidily, we will send a new ball screw for free or give a total refund. What you need to do is to message us through Amazon.
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.

[DURABLE]: The structure of the flange and threaded nut is durable,which is made from high strength cast iron with black powder coating..
[PRECISION MACHINING]: The lead screw is precision-machined so that it can run smoothly when it is turned on and off..
[SPECIFICATIONS]: The lead screw is 1-3/16 inch in diameter, with single-lead Acme threads and 3 threads per inch..
[CLAMPING CAPACITY]: The clamping capacity is 17 inches (less the thickness of the jaw) and total length is 22.8 inches..
[INCLUSIVE SIZE]: It will accept a 1 inch diameter handle (not included)..

Lead: 5 mm. The ball screw is made of high-quality and durable CF54 steel that is wear-proof and resistant to high temperatures. It provides a helical raceway for ball bearings, which act as a precision screw, playing an essential role in situations where high precision is necessary..
High Mechanical Efficiency: Compared to alternatives, the linear motion kit has higher mechanical efficiency and is four times the Acme lead screw of the same size..
Mute Operation: The ball screw kit features an accuracy grade of C7 with bearing fits less than 0.03 mm, making little noise while running..
Little Sliding Friction: The CNC part bears very little sliding friction between the nut and screw, and therefore longer service life..
Wide Application: The linear motion actuator is widely applied to CNC router, machine tools, robots, precision assembly equipment, etc..

brass nut, with 4 holes for fixing to the machine.
If you want higher accuracy, it is recommended to use the anti backlash spring loaded nut.
