***Disclaimer: The following summary contains information gathered from various sources such as product descriptions, technical specifications and catalogs. While efforts have been made to provide accurate details, inaccuracies may occur. It is advised to verify all information by contacting Bosch Rexroth directly.***
The Bosch Rexroth SEM-E-S 25X10RX3-4 (R151224014) is a high-precision ball screw assembly designed for linear motion applications requiring tight tolerances and smooth operation. This adjustable preload single nut SEMES is engineered with a nominal diameter of 25 mm and a lead of 10 mm, providing accurate and repeatable movement. The ball screw features a right-hand direction lead, standard seals, and standard axial clearance, ensuring reliable performance in various operational conditions. The SEM-E-S 25X10RX3-4 is part of the Standard series and falls under the product group ID for screw drive nuts within ball screw assemblies. It has been constructed to accommodate a dynamic load capacity (C) specific to tolerance grades T3 and T4. Users should refer to the correction factor f_sub_ac_sub for other tolerance grades as outlined in the technical notes provided by Bosch Rexroth. With an operating temperature range from minimum to maximum degrees Celsius, this ball screw can sustain continuous operation at high temperatures with temporary peaks even higher, with measurements taken on the outer shell of the nut. This capability ensures that it can meet the demands of various environmental conditions without compromising its function or lifespan. The SEM-E-S 25X10RX3-4's design includes multiple ball track turns, contributing to its high efficiency and load-bearing capabilities. The static load rating (C0) and dynamic load capacity are indicative of its robustness for sustained use. Moreover, it has been crafted with an eye on weight optimization without sacrificing performance, making it suitable for applications where weight is a critical factor. Overall, this Bosch Rexroth ball screw assembly is characterized by its zero-clearance adjustable single nut design, offering precise control over motion systems in industrial settings where accuracy is paramount. Its construction adheres strictly to quality standards ensuring reliability and longevity in demanding operational scenarios.
