The Bosch Rexroth FEM-E-S 12X5RX2-3 (R153246023) is a high-precision ball screw assembly designed for linear motion applications requiring accuracy and efficiency. This single nut with flange from the Miniature series features a nominal diameter of 12 mm and a lead of 5 mm, facilitating right-hand direction movement. It is engineered with a ball diameter (Dw) that complements its design, ensuring smooth operation across its multiple ball track turns. The FEM-E-S 12X5RX2-3 nut is equipped with standard seals to protect against contaminants and has standard axial clearance to maintain performance over time. It adheres to Rexroth's rigorous tolerance grade T for precise operations, and users should note that load capacities are valid only for this tolerance grade; other grades may require the use of correction factors as specified in the technical documentation. This screw drive nut falls under Productgroup ID A, indicating its categorization within Bosch Rexroth's product offerings. The dynamic load capacity and static load rating are optimized to meet the demands of various applications while maintaining structural integrity under load. With an operating temperature range from -20°C to +80°C, this unit can handle varying environmental conditions without compromising performance. The maximum permissible linear speed (vmax) is detailed in the characteristic speed documentation provided by Bosch Rexroth, which also includes critical speed information necessary for project planning. The FEM-E-S 12X5RX2-3 boasts a compact weight and size, making it suitable for applications where space constraints are a consideration without sacrificing load-bearing capacity or precision. Its robust design ensures reliability in demanding applications where consistent linear motion is required.
