The Bosch Rexroth ZEV-E-S 12X5RX2-3 (R254243005) is a high-precision screw-in nut designed for ball screw assemblies in the miniature series. This particular model features a nominal diameter and right-hand lead, ensuring compatibility with specific design requirements. It is crafted with a standard seal and standard axial clearance to provide reliable performance in various applications. The ZEV-E-S 12X5RX2-3 screw-in nut is built to accommodate a ball diameter Dw and has a number of ball track turns i, adhering to Rexroth's connection dimensions. It incorporates low-friction seals and comes in preload class C with tolerance grade T, which ensures optimal functionality within its operational parameters. This screw drive nut can withstand dynamic load capacities as specified for tolerance grade T, but users should refer to the correction factor fsubacsub for other tolerance grades as stated in the General Technical Notes and Information Technical Data. The static load rating C also follows these guidelines. Optimized for smooth motion control, this model has a maximum permissible linear speed vmax m/min and operates efficiently within a temperature range of -20°C to +80°C. The permissible operating temperatures allow for continuous use up to 80°C with temporary peaks up to 100°C, measured on the outer shell of the nut. The Bosch Rexroth ZEV-E-S 12X5RX2-3 maintains its robustness with a weight of only 0.1 kg while providing an essential component for miniature ball screw systems. Its size dimensions ensure it meets specific space requirements while delivering consistent performance in demanding applications. In summary, this product offers reliable operation within its specified temperature range and load capacities, making it an integral part of precision-driven mechanical systems where miniature ball screws are utilized.
