The Bosch Rexroth FEM-E-S 40X5RX35-5 (R151241013) is a high-precision ball screw assembly designed for linear motion applications. This single nut with a flange features standard seals and standard axial clearance, ensuring reliable operation and longevity. The product has a nominal diameter of 40 mm and a lead of 5 mm, with the right-hand thread direction being standard. It incorporates a ball diameter that complements its design for smooth motion. This particular model is constructed to meet the rigorous demands of various applications, offering an impressive dynamic load capacity and static load rating, signifying its ability to handle substantial loads without compromising performance. It is engineered with Rexroth connection dimensions for seamless integration into existing systems, and it comes in preload classes ranging from C0 to C3 to accommodate different application requirements. The FEM-E-S 40X5RX35-5 operates efficiently within a temperature range of -10°C to +80°C, which can endure temporary peaks up to 100°C when necessary. Such thermal resilience is measured on the outer shell of the nut, indicating the unit's capability to maintain performance under varying environmental conditions. The maximum permissible linear speed (vmax) ensures that this ball screw assembly can operate at speeds suitable for a wide array of industrial tasks while maintaining precision. Furthermore, this model boasts Rexroth mounting dimensions and has been manufactured adhering to tolerance grade T7 for sizes as per the product overview for screws. Users can expect consistent quality and reliability from this component due to its adherence to stringent technical standards. With its robust construction and technical specifications, the Bosch Rexroth FEM-E-S 40X5RX35-5 ball screw assembly represents a dependable solution for those requiring precise linear motion control in their machinery or equipment setups.
