Characteristics of ball screws High quality, precision solutions for the Aerospace and Industrial sectors UMBRAGROUP is a company with decades of experience in the design and production of ball screws. It is a world leader in supplying these components for the aerospace and industrial sectors, with close to 50 years of experience and know-how. When standard technology is unable to meet customer needs, what represents a problem for other suppliers becomes the opportunity for the UMBRA Group to study new solutions. Why is UMBRAGROUP a world leader in the production of ball screws and high precision components? Because it can design and produce screws capable of responding to an increasingly complex and competitive market, guaranteeing a wide range of types and dimensional combinations, technical solutions and dedicated components. Screws are the basic component of all applications where rapid, precise and reliable movements are required. The company offers a complete range of ball screws, capable of meeting stringent quality requirements. UMBRAGROUP provides the best technology for the highest quality, in all circumstances. What is a ball screw? The ball screw is a high-performance drive screw, where the balls perform a rolling motion between the axis of the screw and its nut. Compared to a conventional slide screw, this component has a drive torque value of one third, or even less. This feature makes it particularly suitable for lower motor energy consumption, ensuring greater reliability, efficiency and resistance even at very high loads. The components designed and manufactured by UMBRAGROUP employ proprietary technologies and innovative and highly technological solutions that bring these advantages to the highest level. UMBRAGROUP technology at your service UMBRAGROUP designs ball screws that must work in difficult environments and withstand heavy loads. They must guarantee maximum operability, quality and efficiency. Therefore, the company constantly invests in Research & Development to propose tailor-made solutions that are unmatched One example is UMBRAGROUP’s use of Cronidur®30, a stainless steel with a high nitrogen content, used in the architecture of alternating ceramic-steel balls which eliminates the friction that causes corrosion and wear of the screws. It's an exclusive and patented UMBRAGROUP technology. The use of Cronidur®30 and the alternating steel-ceramic architecture ensures extreme reliability even in space, where extreme conditions make the materials more susceptible to damage. Another example is the use of screws with recirculation on the shaft rather than on the nut, used in short- stroke industrial applications - replacing hydraulic jacks - which has made it possible to obtain perfectly sealed and high-performing linear motion systems. The combination of materials and cutting-edge technologies in the production of ball screws allows to: eliminate the problems of corrosion and premature wear typical of traditional screws; have high dynamics and precision; ensure high load capacity and force density; ensure the reliability of the systems; obtain considerable surface hardness; have excellent resistance to corrosion; give greater efficiency to the system; work with reduced working temperatures; eliminate overhaul and lubrication for the entire life cycle; Offer higher positioning accuracy.
