The Bosch Rexroth FEM-E-B 20X5RX3-4 (R150211083) is a high-precision ball screw assembly designed for linear motion applications. This particular model features a single nut with a flange, conforming to the mounting dimensions similar to DIN 69051, Part 5, flange type B. The nut is equipped with standard seals and standard axial clearance, ensuring reliable operation and longevity. With a nominal diameter of 20 mm and a lead of 5 mm, this ball screw assembly is engineered for efficient motion transfer. The ball diameter (Dw) and the number of ball track turns (i) are optimized for smooth movement and high load capacities, which are only valid for tolerance grades T7 and T9 as specified in the product technical notes. This model boasts an impressive dynamic load rating (C), highlighting its capability to handle significant loads while maintaining precision. Additionally, the static load rating also underscores its strength and durability under stationary conditions. It is important to note that maximum permissible speeds (vmax) are outlined in the Characteristic speed (dn) section, and critical speeds (ncr) can be found in the Calculation and examples section of the technical notes. The FEM-E-B 20X5RX3-4 is designed to operate within a temperature range of -10°C to +80°C continuously, with temporary peaks up to +100°C permissible without compromising function or integrity. These temperatures are measured on the outer shell of the nut. The unit's weight contributes to its robustness without sacrificing performance. Overall, this Bosch Rexroth ball screw assembly provides a reliable solution for applications requiring precise linear motion control with high load capacity and resilience under varying temperatures. It's an integral component suitable for various mechanical systems that demand accuracy and efficiency in their screw drive mechanisms.
