The Bosch Rexroth ZEM-E-K 20X20RX35-3 (R151217207) is a high-precision ball screw assembly designed for linear motion applications. This cylindrical single nut model is part of the standard series and is characterized by its robust construction and reliable performance under demanding conditions. The ZEM-E-K 20X20RX35-3 features a nominal diameter of 20mm with a lead of right-handed threads, making it suitable for various mechanical setups that require precise linear movement. The nut is equipped with standard seals to protect against contaminants and offers standard axial clearance to ensure smooth operation. It comes with a dynamic load capacity which ensures durability and a long service life under dynamic conditions. The static load rating further attests to its ability to withstand static forces without compromising performance. With an operating temperature range from minimum to maximum degrees Celsius, this ball screw assembly can handle continuous operations at elevated temperatures, with temporary peaks allowed within specified limits. It maintains stability in terms of thermal expansion and performance consistency across the temperature spectrum. The ZEM-E-K 20X20RX35-3 also boasts a maximum permissible linear speed, highlighting its capability for high-speed applications while maintaining accuracy and efficiency. The product's design includes several preload classes and tolerance grades (T2, T3) that cater to different application requirements, ensuring optimal preload and minimizing axial play for precision tasks. This Bosch Rexroth ball screw nut type ZEMEK is versatile enough to be used in left-hand versions in some cases, offering flexibility for various design configurations. Its weight has been optimized for its size category without compromising on strength or rigidity, making it an excellent choice for designers seeking a balance between mass and performance in their linear motion systems. In summary, the Bosch Rexroth ZEM-E-K 20X20RX35-3 ball screw assembly represents an advanced solution for precise linear movements required in various industrial applications where durability, reliability, and high performance are essential.
