The Bosch Rexroth SEM-E-C 63X20RX65-5 (R151267076) is an adjustable preload single nut ball screw assembly designed for precision linear movement applications. This SEMEC nut has a nominal diameter of 63mm and a lead of 20mm, with a right-hand thread direction. It features a flange type C mounting, which aligns with DIN standards, ensuring compatibility with a wide range of equipment designs. The ball screw nut is engineered to provide zero-clearance due to its adjustable preload capability, enhancing system rigidity and reducing axial play for applications requiring high precision. The product is classified under tolerance grade T, which indicates its high level of manufacturing precision for sizes as outlined in the product overview for screws. This model incorporates standard seals to protect against contaminants and employs standard axial clearance for optimal performance. It has been designed to operate within a temperature range of -10°C to +80°C continuously, with temporary peaks up to +100°C permissible without affecting its integrity or performance. The dynamic load capacity C and static load rating C are specified for tolerance grades T3 and T7; however, users should refer to the correction factor f_a_c when operating under different tolerance grades. The SEM-E-C 63X20RX65-5 can achieve maximum permissible linear speeds as dictated by characteristic speed d_n and critical speed n_cr parameters. It boasts a substantial dynamic load capacity and comes with a weight specification that reflects its robust construction while still maintaining efficiency in operation. Overall, this ball screw assembly from Bosch Rexroth is an essential component for systems requiring precise linear motion control, such as in CNC machinery, automation setups, and other advanced mechanical applications where reliability and accuracy are paramount.
