The Bosch Rexroth ZEM-E-K 12X5RX2-3 (R153246225) is a high-precision cylindrical single nut designed for ball screw assemblies in the Miniature series. This nut features a nominal diameter and lead with a right-hand thread direction, ensuring compatibility with specific screw drive requirements. It is equipped with standard seals and standard axial clearance to maintain its performance in various operating conditions. With a tolerance grade of T, the ZEM-E-K 12X5RX2-3 is engineered to deliver reliable performance under dynamic load capacities, as specified for this tolerance grade. Users are advised to refer to correction factors for other tolerance grades detailed in the General Technical Notes and Information section of Bosch Rexroth's technical documentation. This ball screw nut operates within a temperature range of -20°C to +80°C, allowing for continuous use at high temperatures up to 80°C and temporary peaks up to 120°C, based on measurements from the outer shell of the nut. The maximum permissible linear speed is denoted by vmax and should be referenced alongside characteristic speed (dn) and critical speed (ncr) values available in technical notes for optimal application planning. The ZEM-E-K 12X5RX2-3 boasts a static load rating that complements its dynamic load capacity, both crucial for ensuring stability and longevity in demanding operational contexts. Its design caters to applications requiring compact yet robust components, with a weight that contributes positively to overall assembly efficiency. Bosch Rexroth's attention to detail in manufacturing this ball screw assembly component ensures it meets stringent industry standards for performance and durability. The ZEM-E-K 12X5RX2-3 serves as an essential part of precise motion control systems where reliability cannot be compromised.
