The Bosch Rexroth ZEM-E-K 20X5RX3-4 (R151211243) is a high-precision ball screw assembly component designed for linear motion applications. This cylindrical single nut ZEMEK is engineered with a nominal diameter (d) and features a right-hand lead (P) that ensures smooth and accurate translation of rotational motion into linear movement. The ball diameter (Dw) and the number of ball track turns (i) are optimized to deliver efficient load distribution and extended service life. Constructed with robust materials, the ZEM-E-K 20X5RX3-4 offers a dynamic load capacity (C) that guarantees performance under varying loads, while adhering to tolerance grade T for precision. The nut type is categorized under the Standard series, ensuring compatibility with a wide range of ball screw assemblies. This model comes equipped with standard seals to prevent contamination and maintain lubrication, enhancing the durability of the assembly. It also has standard axial clearance to accommodate thermal expansion during operation. The maximum operating temperature range for this component spans from a minimum bearing temperature up to a maximum permissible linear speed (vmax), allowing it to operate effectively in diverse environmental conditions. The static load rating (C0) further indicates its capability to withstand resting forces without deformation. Moreover, this product can handle continuous operating temperatures while still supporting temporary peaks without compromising its structural integrity or performance. With its considerable size L and nominal size specifications, the Bosch Rexroth ZEM-E-K 20X5RX3-4 remains lightweight yet durable. It is an essential part of any ball screw assembly that requires reliability, precision, and efficiency in translating rotational motion into linear action.
