ballscrews, also called a ball bearing screws, recirculating ballscrews, etc., consist of a screw spindle and a nut integrated with balls and the balls return mechanism, return tubes or return caps. Ballscrews are the most common type of screws used in industrial machinery and precision machines. The primary function of a ballscrew is to convert rotary motion to linear motion or torque to thrust, and vice versa, with the features of high accuracy, reversibility and efficiency. We provides a wide range of ballscrews to satisfy your special requirements.the combination of state-of-the-art machining technology, manufacturing experiences, and engineering expertise makes our ballscrew users high-tech winners. We uses precise procedures to create exact groove profiles, either by grinding or precision rolling. Accurate heat treatment is also used to ensure the hardness of our ballscrews. These result in maximum load capacity and service life.our precision ballscrews provide the most smooth and accurate movement, together with low drive torque, high stiffness and quiet motion with predictable lengthened service life. Our rolled ballscrews also provide smooth movement and long life for general applications with less precision in lower price. Our modern facilities, highly skilled engineers, quality manufacturing and assembly processes, and uses quality materials to meet your special requirements.it is our pleasure to provide you with the technical information and selection procedure to choose the right ballscrews for your applications through this catalogue.

lead screw a leadscrew (or lead screw), also known as a power screw or translation screw, is a screw used as a linkage in a machine, to translate turning motion into linear motion. C45 and a2 stainless steel were chosen because in addition to their natural qualities as good construction materials, after rolling they give very good surface hardness and finish on the thread sides. A4 stainless steel also has excellent corrosion resistance. C15 is an excellent quality - price compromise. After rolling, c15 has surface hardness of approximately 160/180 hb, c45 approximately 250 hb, a2 stainless approximately 260 hb and a4 stainless approximately 280 hb while roughness is less than 1 m ra for all. These two features are decisive factors for qualitative appraisal of trapezoidal screws because they give very small friction coefficients, much lower than those obtainable with machined screws where other conditions such as speed, load and lubrication are equal. Our trapezoidal screws with bronze nuts give traversing systems with efficiency, and quietness the compared with coupling with machined screws because of the low friction coefficient the amount of heat generated during movement is limited with resulting smaller nut heating . Nut life is also increased. We make nuts with 10 kinds of material to better meet the various requirements.
