The Bosch Rexroth FEP-E-S 32X32RX3969-12X4 (R252230001) is a high-precision ball screw assembly designed for linear motion applications requiring efficiency and accuracy. This single nut with a flange features recirculation caps and comes equipped with standard seals and standard axial clearance, ensuring smooth operation and longevity. The nut is part of the FEPES series, known for its robust performance and reliability. Crafted with a nominal diameter of 32 mm and a lead of 32 mm to the right, this ball screw assembly is engineered for precision. It incorporates a ball diameter that complements its design, along with an optimal number of ball track turns to facilitate effective recirculation. The product adheres to tolerance grade T, which guarantees that the dynamic load capacities are maintained as specified. This model's maximum operating temperature range indicates resilience in various working conditions, allowing continuous operation at temperatures up to a certain degree Celsius while also accommodating temporary peaks at higher temperatures measured on the outer shell of the nut. It boasts an impressive static load rating, highlighting its capacity to withstand loads without movement. The FEP-E-S 32X32RX3969-12X4 is designed to achieve maximum permissible linear speeds while maintaining stability and performance integrity throughout its operational temperature range. Its construction allows for right-hand lead directionality, making it suitable for diverse industrial applications. In terms of physical attributes, the unit's size specifications are detailed alongside its weight, which reflects Bosch Rexroth's commitment to providing comprehensive information for proper integration into various systems. Overall, this ball screw assembly is characterized by its exceptional dynamic load capacity and adherence to stringent technical standards, marking it as an essential component for sophisticated mechanical setups where precision linear movement is paramount.
