The Bosch Rexroth FLANGED BEARING FEC-F-B 50 (R159B45001) is a high-precision fixed bearing designed to provide superior support and stability in linear motion applications. This robust assembly group bearing unit FECF, size x RR, is engineered to accommodate screw ends type and includes a precision flanged housing made of durable steel. It features an angular contact thrust ball bearing LGS and a slotted nut NMB, ensuring reliable operation and longevity. This bearing unit boasts impressive rigidity against tilting (Rkl), which helps maintain alignment and reduces stress on connected components. The limit speed for grease lubrication (nmax) is specified to ensure optimal performance under low load conditions with efficient heat dissipation. The outer diameter (D) and size (d) of the bearing are meticulously crafted to meet precise specifications, contributing to its overall effectiveness in various applications. The FLANGED BEARING FEC-F-B 50 also exhibits low bearing frictional torque with seal (MRb), which minimizes resistance and wear during operation. The specified tightening torque for the set screw (MAG) ensures secure mounting, while the rigidity of the bearing axial (RFB) provides excellent resistance to axial loads. Its static load rating (C0) indicates the maximum stationary load it can withstand without permanent deformation. This product offers a dynamic load capacity (C), reflecting its ability to handle varying forces during motion. It comes with accessories suitable for Rexroth ball screw assemblies Bearings Size L, enhancing its compatibility and ease of integration into existing systems. Weighing in at . kg, the FLANGED BEARING FEC-F-B 50 maintains a balance between strength and weight, making it suitable for a variety of industrial applications where precision and reliability are paramount.
