The Bosch Rexroth FEM-E-C 20X10RX3-4 (R150214065) is a high-precision ball screw assembly designed for linear motion applications. This single nut with flange FEMEC model boasts a nominal diameter of 20 mm and a lead of 10 mm, ensuring smooth and accurate movement. The ball diameter Dw and the number of ball track turns i are meticulously engineered to provide optimal performance, while the mounting dimensions are similar to DIN standards, ensuring compatibility with a wide range of equipment. With a flange type C design, this ball screw assembly also has an option for flange type B, providing versatility for different mounting scenarios. The nut comes with standard seals and standard axial clearance, enhancing its durability and lifespan under various operating conditions. It is available in preload classes ranging from C0 to C5 and tolerance grade T3, which applies to sizes as per the product overview for screws. The FEM-E-C 20X10RX3-4 operates within a temperature range of -10°C to 100°C, making it suitable for use in environments with varying thermal conditions. It can handle dynamic loads efficiently as indicated by its dynamic load capacity C0; however, users should refer to the correction factor f_a for tolerance grades other than T3 and T5 when calculating load capacities. This model is part of the Standard series in Bosch Rexroth's product lineup under Productgroup ID Nut or Screw Drive Nut. Its maximum permissible linear speed vmax ensures that it can keep up with demanding applications without compromising on performance. In terms of physical attributes, the FEM-E-C 20X10RX3-4 has a specific weight and size L that aligns with its nominal size designation. This ball screw assembly is an ideal solution for those seeking precision linear movement in their machinery or automation systems.
