The Bosch Rexroth FEM-E-B 50X20RX65-5 (R150257084) is a high-precision ball screw assembly designed for linear motion applications requiring accuracy and reliability. This single nut with flange FEMEB is engineered with a nominal diameter of 50 mm and a lead of 20 mm, suitable for converting rotary motion into linear motion with minimal friction. The ball screw nut features a flange type B mounting, conforming to DIN 69051, Part 5 standards, which ensures compatibility with a wide range of equipment designs. The FEM-E-B 50X20RX65-5 is equipped with standard seals to protect against contaminants and boasts standard axial clearance to maintain performance under varying loads and operating conditions. It supports a dynamic load capacity (C) that is specified for tolerance grades T7 and T9; however, for other tolerance grades, it's important to apply the appropriate correction factor as noted in the product's technical documentation. With a preload class ranging from C0 to C5, this ball screw nut can be tailored to the required level of rigidity and precision for specific applications. The temperature range for operation extends from -10°C to +80°C continuously, with temporary peaks up to +100°C permissible, ensuring stability even in challenging thermal environments. This Bosch Rexroth ball screw assembly boasts an impressive maximum permissible linear speed (vmax), though the exact value should be referenced from the characteristic speed (dn) section in the technical notes provided by Bosch Rexroth. The product also comes with a significant static load rating (C0) and adheres to strict manufacturing tolerances for size L and size D dimensions. Overall, the Bosch Rexroth FEM-E-B 50X20RX65-5 ball screw assembly represents an ideal solution for applications demanding precise linear movement and robust performance in various industrial settings. Its construction reflects Bosch Rexroth's commitment to quality and durability in automation technology components.
