Thomson Recirculating Ball Screws Broad range of precision products providing a “just right” solution Thomson has manufactured ball screws and nuts for nearly 60 years in Europe. Thanks to our quality management and culture of continuous improvement, we can offer the highest levels of performance, quality and reliability. Our products are used in high-precision machines and some of the most demanding industrial applications. Superior Precision Thomson ball screws are manufactured using patented, German-engineered Precision Screw Forming Technology (PST), which provides an accuracy of 23 microns/300...

Metric Ball Screws Application Support Not all ball screws are alike. Differences in design, quality, materials, manufacturing and application support are all factors that affect their performance and extend their lives. Consistent Quality and Delivery A combination of advanced engineering and proprietary manufacturing processes consistently exceed performance, precision and life versus comparable ball screws. Thomson field sales and applications engineering personnel are skilled at evaluating your requirements and designing assemblies that fit your needs. They can also quickly and knowledgeably...

• Examples include mills, water jets, plasma cutters and automatic welders. • Ball-screw-driven horizontal and vertical axes must move heavy loads accurately and safely, while providing long and reliable life with minimum maintenance. • Ball screws are necessary to handle high loads in a short stroke. • Precision ball screws are required to control system accuracy

Metric Ball Screws Robotics and Factory Automation • No matter the size, stroke or load capacity of the ball screw needed, high accuracy as well as smooth and quiet travel are important. • Examples include patient handling, ergonomics and critical system actuation. • Smooth, quiet and precise drives are necessary for todays advanced medical imaging systems to provide accurate diagnostics for patients. • The familiar sound we hear during air travel is the reliable operation of ball screws driving flight-critical systems such as flaps, stabilizers, landing gear, hatches and fly-by-wire systems....

Ball Screws Thomson precision-manufactured rolled, whirled and ground ball screws featuring a proprietary gothic arch thread profile designed to maximize load capacity and life. Rolled Ball Screws Rolled ball screw shafts are manufactured using our patented, German-engineered Precision Screw Forming Technology (PST) manufacturing process, which provides consistent accuracy of 23 µm/300 mm standard and 12 µm/300 mm upon request. Whirled Ball Screws Whirling is a hard turning process that provides an affordable alternative to grinding when applications require higher precision levels than is achievable...

Metric Ball Screws Ball Nuts Thomson offers a wide breadth of ball nut configurations to seamlessly interface to the application. Most ball nuts have profiled wiper rings to reduce the escape of lubricant and prevent the ingress of dirt. Ball Nut Mounting Alternatives Thomson offers flanged ball nuts that are attached via a set of mounting holes or cylindrical nuts that have a keyway or external thread. Custom interfaces such as trunnions and nut housings are also available. Ball Recirculation Systems Thomson manufactures ball nuts with three different ball recirculation systems depending on...

Selecting a ball screw assembly for a specific application is often about finding the smallest and most cost-effective solution that does the job. While it may seem like the same process every time, no two applications are alike, so it is important to consider the unique circumstances during the design phase. This list shows the most common design considerations used to select a ball screw assembly: • Compression or tension load • Linear velocity • Positional accuracy and repeatability • Required life expectancy • Mounting configuration • Dimensional constraints • Input power requirements • Environmental...

Metric Ball Screws Sizing and Selection Process To select the optimal ball screw solution for your application, the following application-related questions and specifications should first be analyzed. LOAD, LIFE AND SPEED? Determine Ball Screw Lead and Diameter. DISTANCE BETWEEN SUPPORTS, STROKE LENGTH AND ORIENTATION? Determine Ball Screw Length, Critical Speed and Required Power. ACCURACY, REPEATABILITY AND STIFFNESS? Determine Ball Screw Type and Ball Nut Preload Configuration. ENVIRONMENTAL CONSIDERATIONS? Determine Overall Suitability, Material Choices, Sealings, Surface Treatments, Wipers...

Ball Screw Size Chart The Thomson ball screw range complies with ISO 3408. All ball nuts, both flanged and cylindrical, are available with connections complying with DIN specifications. Every shaft can be supplied with customized end journals, and upon request, customers can order screws with an annealed end for machining their own end journal.
