The Bosch Rexroth FEM-E-S 40X10LX6-4 (R155244003) is a high-precision ball screw assembly designed for linear motion applications. This model features a single nut with flange from the standard series, offering reliable and efficient performance. The nut has a nominal diameter of 40 mm and a lead of 10 mm, which is left-handed, making it suitable for specific directional requirements. It comes with standard seals and standard axial clearance to ensure smooth operation. The FEM-E-S 40X10LX6-4 is equipped with a dynamic load capacity that is specified for tolerance grades T3 and T5. Users should refer to the correction factor f_a if other tolerance grades are applied. It boasts an impressive static load rating, ensuring durability and longevity under various loading conditions. The nut's operating temperature range spans from a minimum bearing temperature to a maximum permissible linear speed, allowing for continuous operation at elevated temperatures with temporary peaks without compromising functionality. This ball screw assembly can achieve high speeds while maintaining precision, as indicated by its characteristic speed d_n and critical speed n_cr parameters in the technical notes section. Its design includes Rexroth connecting dimensions for compatibility and ease of installation in various industrial settings. Weighing only 'weight' kg, the FEM-E-S 40X10LX6-4 remains lightweight yet robust enough to handle substantial loads. Its compact size L ensures it can be integrated into space-constrained environments without sacrificing performance. With its comprehensive technical specifications and reliable design, this Bosch Rexroth ball screw assembly is an essential component for advanced mechanical systems requiring precise linear motion control.
