The Bosch Rexroth ZEM-E-S 20X20RX35-3 (R151217052) is a high-precision ball screw assembly designed for linear motion applications. This cylindrical single nut ZEMES model features a nominal diameter of 20mm and a lead of 20mm with a right-hand thread direction. It is equipped with standard seals and standard axial clearance to ensure smooth operation and longevity. The nut has been constructed to accommodate a ball diameter that complements its size, enhancing load-bearing capabilities. This ball screw assembly operates within an impressive temperature range, maintaining functionality at continuous temperatures up to 80°C, with temporary peaks permissible up to 100°C, as measured on the outer shell of the nut. It boasts a dynamic load capacity that is specified for tolerance grades T7 and T5; however, for other tolerance grades, it's important to apply the correction factor as outlined in the technical notes provided by Bosch Rexroth. The ZEM-E-S 20X20RX35-3 is part of Bosch Rexroth's Standard series and falls under the product group ID indicating it's a screw drive nut intended for ball screw assemblies. The maximum permissible linear speed (vmax) and static load rating are detailed in the technical specifications, ensuring users can accurately assess its suitability for their specific application requirements. With its robust construction and reliable performance characteristics, this ball screw assembly is suitable for various applications requiring precise linear movement. Its design includes multiple ball track turns that align with Rexroth connection dimensions. Users can expect consistent performance from this component due to its preload class C precision and adherence to tolerance grade standards. The unit's weight has been optimized for its size category, making it an efficient choice without compromising on strength or durability.
