The Bosch Rexroth ZEM-E-S 20X5RX3-5 (R151211012) is a precision-engineered ball screw assembly component designed for high-performance motion control applications. This cylindrical single nut ZEMES is part of the standard series, featuring a nominal diameter (d), right-hand lead direction, and a lead (P) that ensures smooth and accurate linear movement. The nut is equipped with standard seals and comes with standard axial clearance to maintain efficiency and longevity under various operating conditions. The ZEM-E-S 20X5RX3-5 has been constructed with a ball diameter (Dw) optimized for the number of ball track turns (i), which are integral to the product's dynamic and static load capacities. These capacities are specifically validated for tolerance grades T3, T5, and T7. Users should consider the correction factor f_a when dealing with other tolerance grades, as outlined in the General Technical Notes and Information Technical Data. This ball screw nut operates efficiently within a temperature range of -10°C to +100°C, allowing continuous operation at temperatures up to 80°C with temporary peaks up to 100°C measured on the outer shell of the nut. The maximum permissible linear speed (v_max) is detailed in characteristic speed (d_n) values provided in technical documentation. Furthermore, this Bosch Rexroth product boasts a preload class C and tolerance grade T, ensuring precise fitting and performance consistency across applications. The weight specification of this particular model guarantees that it will not significantly add to the overall mass of machinery, maintaining an efficient design. Overall, the Bosch Rexroth ZEM-E-S 20X5RX3-5 ball screw assembly nut is crafted for reliability and accuracy in various screw drive applications where precision linear movement is critical. Its robust design ensures it can withstand demanding operational conditions while providing superior performance in motion control tasks.
