The Bosch Rexroth FDM-E-C 50X10RX6-6 (R150254076) is a high-precision ball screw assembly designed for linear motion applications requiring efficiency and accuracy. This double nut with a flange is part of the standard series, ensuring compatibility with a wide range of equipment. The product features a nominal diameter (d) and lead (P) with a right-hand thread direction, making it suitable for various industrial applications. Constructed to provide reliable performance, the FDM-E-C 50X10RX6-6 boasts mounting dimensions that are similar to DIN standards, specifically with a flange type C. It comes equipped with seals and is preloaded in class C, ensuring minimal axial play and consistent rigidity under load. The tolerance grade is T, which aligns with the general technical specifications outlined for screws in the product overview. The ball screw assembly has an impressive dynamic load capacity and static load rating, both validated for tolerance grades T3 and T5. Users should refer to correction factors if operating outside these tolerance grades. Its maximum permissible linear speed (vmax) indicates its capability to handle high-speed applications without compromising on performance. Bosch Rexroth has engineered this component to operate within a temperature range of -10°C to +100°C, accommodating varying environmental conditions while maintaining its integrity. The product can endure continuous operation at temperatures up to 80°C and withstand temporary peaks up to 100°C. The FDM-E-C 50X10RX6-6's design also includes critical speed considerations and characteristic speeds detailed in the technical notes provided by Bosch Rexroth. With a weight of approximately 4.2 kilograms, this ball screw assembly combines robust construction with precision engineering, making it an essential component for demanding linear motion systems.
