The Bosch Rexroth SEM-E-C 40X40RX6-3 (R151249055) is a high-precision ball screw assembly designed to provide efficient linear motion with adjustable preload capabilities. This single nut SEMEC model is engineered to have mounting dimensions similar to DIN, Part 2, flange type C, and comes equipped with standard seals and standard axial clearance. The nut has a nominal diameter (d) and a right-hand lead (P), which is complemented by a specific ball diameter (Dw) and a number of ball track turns (i). The SEM-E-C 40X40RX6-3 features an adjustable preload that enhances the rigidity of the assembly and allows for zero-clearance operation, resulting in precise positioning and reduced backlash. This makes it particularly suitable for applications requiring high levels of accuracy and repeatability. The tolerance grade T ensures that the unit meets stringent quality standards. This ball screw assembly boasts an impressive dynamic load capacity (C), which is valid for tolerance grades T3 and T5. Users are advised to refer to the correction factor f_ac if other tolerance grades are applied. The static load rating also adheres to these conditions. The SEM-E-C 40X40RX6-3 can operate within a temperature range of -10°C to +80°C, maintaining performance during continuous operation at temperatures up to 80°C with temporary peaks permissible up to 100°C. These temperature measurements are taken on the outer shell of the nut. Additionally, this model offers a maximum permissible linear speed (v_max) that ensures efficient operation without compromising system integrity. It's critical for users to consider characteristic speed (d_n), critical speed (n_cr), and other technical notes when planning their projects. The product comes with a specific size designation L, indicating its dimensions, which contributes to its weight specification. With its robust design, reliable performance, and capability for precise control in linear motion applications, the Bosch Rexroth SEM-E-C 40X40RX6-3 ball screw assembly is an essential component for various mechanical systems requiring meticulous motion control.
