The Bosch Rexroth FEM-E-C 50X16RX6-6 (R150256066) is a high-precision ball screw assembly designed for linear motion applications requiring efficiency and accuracy. This single nut with flange FEMEC, size 50x16R, features a nominal diameter (d) and lead (P) that are right-handed, with a ball diameter (Dw) optimized for smooth motion. The number of ball track turns (i) and the mounting dimensions are similar to DIN standards, ensuring compatibility with a wide range of industrial equipment. This model comes equipped with standard seals and standard axial clearance to maintain performance under varying conditions. It offers multiple preload classes ranging from C0 to C5, tailored to match specific application requirements for rigidity and precision. The tolerance grade T is maintained across sizes as per the product overview for screws, which can be referenced in the general technical notes and information section. The FEM-E-C 50X16RX6-6 operates within a temperature range of -10°C to +100°C, supporting continuous use at temperatures up to 80°C with temporary peaks permissible at 100°C when measured on the outer shell of the nut. Its dynamic load capacity ensures reliable performance under varying load conditions. For applications demanding specific speed requirements, this ball screw assembly can achieve a maximum permissible linear speed (vmax), which should be consulted in the characteristic speed (dn) section under technical notes. The static load rating (C0) is also provided for reference when assessing suitability for static or low-dynamic applications. In terms of physical characteristics, this model has a weight specification that complements its nominal size parameters, making it suitable for integration without significantly affecting overall system mass. As part of Bosch Rexroth's standard series of screw drive nuts, the FEM-E-C 50X16RX6-6 represents a reliable component for precision-driven linear movement tasks in various mechanical setups.
