The Bosch Rexroth FLANGED BEARING FEC-F-B 25 (R159B42501) is a meticulously engineered fixed bearing unit designed to provide high precision and rigidity in linear motion applications. This model is part of the assembly group bearing unit FECF, specifically sized for high-performance tasks. The fixed bearing includes an angular contact thrust ball bearing LGS, which ensures smooth operation and efficient load handling. It comes with a slotted nut NMB, tailored for compatibility with screw ends of various types. The bearing assembly is constructed from a precision flanged housing made of robust steel, which encases the angular contact ball bearing LGS. This combination offers exceptional rigidity against tilting (Rkl), enhancing the stability and accuracy of the system it is integrated into. The FLANGED BEARING FEC-F-B 25 operates effectively at a limit speed for grease lubrication (nmax), with guideline values indicating suitability for conditions involving low load on the bearing, optimal heat dissipation, and use of appropriate grease lubricants. With an outer diameter (D) and size (d) specified by Bosch Rexroth, this model ensures a perfect fit in corresponding applications. The bearing's frictional torque with seal (MRb) is measured at specific RPMs to guarantee efficiency during operation. Additionally, it has defined tightening torques for both the set screw (MAG) and DIN standards compliance. This model boasts substantial axial rigidity (RFB), a high static load rating (C), and dynamic load capacity (Cd), signifying its ability to withstand both static and dynamic stresses while maintaining performance integrity. The weight specifications are provided to facilitate proper handling and integration into systems. Overall, the Bosch Rexroth FLANGED BEARING FEC-F-B 25 is an essential component for those needing reliable and precise linear motion solutions within their mechanical assemblies or machinery.
