The Bosch Rexroth FEP-E-S 25X25RX35-12X4 (R252220001) is a high-precision ball screw assembly designed for linear motion applications where accuracy and rigidity are critical. This single nut with flange features recirculation caps and comes with standard seals and standard axial clearance to ensure smooth operation. The nut has a nominal diameter of 25 mm, a lead of 35 mm, and is designed for right-hand thread direction. The FEP-E-S series is characterized by its robust design which includes a ball diameter that ensures optimal load distribution across multiple ball track turns. This configuration provides the assembly with an impressive dynamic load capacity, although the exact value is specific to the tolerance grade T. Users should note that different tolerance grades may require the use of a correction factor as detailed in the General Technical Notes and Information Technical Data. This screw drive nut operates within a temperature range from minimum to maximum bearing temperatures—details of which are specified in the technical notes—making it suitable for various operating environments. It can withstand continuous operating temperatures with temporary peaks at higher levels, measured on the outer shell of the nut. The Bosch Rexroth FEP-E-S 25X25RX35-12X4 ball screw assembly also has a predefined maximum permissible linear speed, which is critical for ensuring safe and effective operation within mechanical systems. The product's weight and dimensions are tailored to meet industry standards for compatibility and performance. Overall, this ball screw assembly from Bosch Rexroth is engineered for durability and performance, making it ideal for precision applications that demand high load capacities and reliable linear motion control.
