议价
加入意向| 滚珠丝杠副是由螺杆、 螺母和球。它的功能是将旋转运动变成直线运动,是进一步的延伸和发展的滚珠丝杠。这种发展的意义是从 slidingaction 进入滚动轴承。与小摩擦,滚珠丝杠副广泛应用于各种工业设备和精密仪器。 应用程序: 1.雕刻机; 2.高速数控机械; 3.半导体设备; 4.自动机械。http: / / www.sinier.cc/ |
| Ball screw is made of screw, nut and ball. it's function is to turn the rotary motion into liner motion, which is a further extension and development of ball screw. the significance of this development is to move into a rolling bearing from slidingaction. with little friction, ball screws are widely used in various industrial equipment and precision instruments. Applications: 1. Engraving machines; 2. High speed CNC machinery; 3. Semi-Conductor equipment; 4. Auto-machinery. http: //www.sinier.cc/ |
