The Bosch Rexroth SEM-E-S 40X20RX6-3 (R151247014) is a high-precision ball screw assembly designed for linear motion applications requiring exact positioning, smooth movement, and reliable long-term performance. This adjustable preload single nut SEMES features a nominal diameter of 40 mm and a lead of 20 mm with a right-hand thread direction. It is equipped with standard seals and standard axial clearance to ensure efficient operation. The SEM-E-S 40X20RX6-3 comes with Rexroth connection dimensions and can accommodate both dynamic and static loads with its robust design. The dynamic load capacity is specified for tolerance grades T3 and T5 only, indicating that it is engineered for precision applications. Users should refer to the correction factor (f_sub_ac_sub) detailed in the General Technical Notes and Information section for other tolerance grades. This ball screw assembly operates within a temperature range of -10°C to +80°C, allowing for continuous use at temperatures up to 80°C and temporary peaks up to 100°C, measured on the nut's outer shell. The maximum permissible linear speed (v_max) ensures efficient operation without compromising the system's integrity or performance. The SEM-E-S 40X20RX6-3 nut type is categorized under the SEMES zero-clearance adjustable single nuts, which are part of Bosch Rexroth's standard series product group. These components are designed to offer zero-clearance through an adjustable preload, optimizing system rigidity and reducing axial play for precise motion control. Additionally, this model incorporates a hole pattern BB for mounting convenience and boasts a size L that corresponds to its nominal size designation. With its comprehensive design considerations, Bosch Rexroth’s SEM-E-S 40X20RX6-3 ball screw assembly represents a reliable solution for demanding linear motion requirements across various applications.
