Is it your first time using ball screws? not sure about your requirements?
Ball screws can be broadly classified as Ground ball screws or Rolled ball screws. The basic difference between the two is the process by which they are manufactured. Rolled ball screws as the name suggests are created by pushing metal rods through rotating tool dies. while in a ground ball screw, the threads are fabricated by abrasives. The rods rotate at high speeds between two machining centres. Given the difference in process that great accuracy can be achieved with ground ballscrews as against rolled ballscrews. This identification is the first step to understanding the accuracy classes in ball screws. A chart given below will explain in detail the different ball screw accuracy classes. Traditionally the ground ball screws are preferred for high accuracy applications, whereas rolled ballscrews are preferred for low cost applications for automation and industrial uses.
Factory automation has seen a wide range of applications being converted to linear motion from rotary motion earlier. Disadvantages of using hydraulics and pneumatic systems has also lead to a huge growth in the industrial use of linear motion products. Ballscrews and linear guideways have helped greatly in this transformation. A ball screw assembly is unique in a lot of ways. It was first manufactured in the year 1898, by H.M.Stevenson & D. Glenn. However, since then the ball screw assembly has seen significant changes and improvements. Ball screw designs have also changed over the years. They are now far more easy to produce and provide a considerable advantage over the other technologies for converting the rotary motion to linear motion. One of the prime causes clients still use lead screws over ball screws is the cost. However, the low friction in ballscrews helps in achieve great mechanical efficiency. Normally it is 90% efficient as against a lead screw which is only 20-25% efficient in converting rotary force to linear movement. THK Ball screws are used extensively in aircraft and missiles to move control surfaces. Also an aircraft's recliner seats uses miniature ball screws from THK. In automobile electric power steering, in semiconductor industries, not to forget the extensive uses in machine tool industry, robots and precision assembly equipment. They are also common in CNC routers for metal and work working applications. Ball screw assembly consists of a threaded screw which moves the nut with minimum friction with the help of ball bearings placed along the inside of the nut. Special seals are placed on the ends for preventing the ball bearings to slip out during movement. Ball screw assembly procedure is complex & difficult to explain over some text in simple words. Its best discussed with explanatory videos over a personalized meeting.
Ball screw backlash strictly speaking is the axial free movement of the ball screw to the ball nut. Ball screw backlash is not rotational in nature. There are special applications which require zero backlash of the ballscrew, this is an inbuilt nature of THK Ball screws. Since all THK ground ball screws have the nut preinstalled at manufacturing facility, all of them have zero backlash. Rolled ballscrews from THK have some backlash unlike the ground ball screws. This point could be important for ball screw selection for special applications.
Ball screw design or the design of the ball nut varies from manufacturer to manufacturer. Most manufacturers have a in house design parameters & catalogs that are based on some key industry standards. However, since ballscrews are used in factory automation and some very special applications, often the designs are customized to need. these customization in ball screw design means that replacements are not easy to find. However, at THK we have the capability to manufacture even single piece to customized information. These products are available with delivery period as small as 30 days, when the industry norm of 90-120 days! Ball screw design pdf are available with us on request.
Ball screw gif attached below shows how a ballscrew works. the mechanics are not easy to understand as in most cases the inside of a ballscrew is not visible. A ball screw gif can help you under the placement of ball bearings in a ball nut and the movement & recirculating rings. Ball screw THK is a commonly searched term on Google that people use when looking for a Ball screw made by the Japanese company. Ball screw THK dealers can also be looked up to get to Industrial Tools & bearing co.
Few key factors that help in ball screw selection are-
1. Ball screw load capacity
2. Ball screw accuracy
3. Ball screw life calculation
4. Backlash in ball screw

Some leading Indian ball screw manufacturers can produce quality products. however, despite the best of their efforts, they cannot manufacture a ball screw with zero backlash. THK has been producing zero backlash ball screws for a long time now. Infact, all ground ball screws from THK sold in Indian market have pre-installed ball nuts on the screw. This helps THK maintain their promise of zero backlash ball screws.
Ball screw nut design plays an important role in ballscrew selection process. Since most applications that use them have space constraints, using the best design becomes critical in the success of the application. Ball screw nuts can be designed without a flange also in special cases. mostly the nut are cylindrical in shape. However some special applications use a ball screw nut design which is rectangular.
