The Bosch Rexroth ZEM-E-S 20X20RX35-2 (R151217012) is a high-precision ball screw assembly designed for linear motion applications. This cylindrical single nut ZEMES features a nominal diameter of 20 mm and a lead of 20 mm, with a right-hand thread direction. The ball screw nut is engineered with standard seals and standard axial clearance to ensure reliable operation. Incorporated with a robust design, the ZEM-E-S 20X20RX35-2 can withstand dynamic load capacities and maintain performance within a specified operating temperature range. The nut type is from the ZEMES cylindrical single nut series, falling under the Standard series product group. It is designed to accommodate high-speed movements with its maximum permissible linear speed, ensuring efficient and smooth motion control in various applications. The assembly comes preloaded in classes C0 to C3, offering different levels of rigidity to match specific application requirements. It also adheres to tolerance grade T7 for sizes as per the product overview for screws, which guarantees precision in its operation. For optimal performance and longevity, this ball screw assembly operates within a temperature range of -10°C to +100°C while handling continuous temperatures up to 80°C and temporary peaks up to 100°C. The Bosch Rexroth ZEM-E-S 20X20RX35-2 is characterized by its low weight and compact size L nominal dimensions, making it suitable for space-constrained installations without compromising on strength or load-bearing capacity. This ball screw nut is an essential component for applications requiring precise linear motion control, such as in automation systems, CNC machinery, and other advanced industrial equipment where reliability and accuracy are paramount.
