The Bosch Rexroth FEM-E-B 25X5RX3-4 (R150221083) is a high-precision ball screw assembly designed for linear motion applications. This single nut with flange FEMEB is engineered to provide smooth, accurate movement and is equipped with standard seals and standard axial clearance. The nominal diameter of the nut is 25 mm, with a lead of 5 mm, and a right-hand thread direction. It features a ball diameter of Dw and multiple ball track turns i, ensuring reliable performance under dynamic load conditions. The FEM-E-B 25X5RX3-4 meets mounting dimensions similar to DIN standards, specifically part flange type B, which facilitates easy integration into various machine designs. The product comes in preload classes ranging from C0 to C5 and tolerance grade T3, ensuring optimal preload and precision for different application requirements. This Bosch Rexroth screw drive nut boasts an impressive dynamic load capacity (C) and static load rating (C0), which are valid for tolerance grades T3 and T7 only; correction factors must be considered for other grades as per the general technical notes. It operates effectively within a temperature range of -10°C to +80°C but can withstand temporary extremes up to +100°C as measured on the outer shell of the nut. The maximum permissible linear speed (vmax) is defined in the technical specifications, while the critical speed (ncr) can be found in the calculation examples provided by Bosch Rexroth. The size D flange diameter and size L thread length come with specific tolerances detailed in the product information. Designed as part of Bosch Rexroth's Standard series, this ball screw assembly has a size D hole pattern BB and size Sx pitch circle diameter for flange mounting. Its robust construction ensures reliability even at high speeds or under substantial loads, making it suitable for various industrial applications requiring precise linear motion control. With a weight of approximately 1 kg and nominal size specifications of 25 x 5 R x 3, this product represents an essential component for sophisticated mechanical systems.
