The Bosch Rexroth BEARING LAN-B-A 17 (R159011730) is a meticulously engineered fixed bearing unit from the assembly group LAN, specifically designed for high precision and rigidity in screw-driven applications. This bearing unit includes an angular contact thrust ball bearing LGN, which is crucial for handling axial loads with high accuracy. It comes with a slotted nut, either NMA or NMZ, to ensure secure fastening and easy installation. The bearing is compatible with screw end types A. The product belongs to the dynamic load capacity C category, which indicates its capability to withstand substantial operational loads. The provided general technical notes and information for bearings emphasize its application-oriented design. The rigidity against tilting Rkl parameter denotes the bearing's resistance to tilting forces, maintaining stability during operation. The BEARING LAN-B-A 17 operates efficiently within its limit speed for grease-lubricated conditions (nmax), ensuring longevity and consistent performance. Its outer diameter D and size d are tailored to fit seamlessly into corresponding housing units. Moreover, the bearing frictional torque with seal MRb provides insight into the minimal resistance encountered during rotation, contributing to energy-efficient operation. This fixed bearing also boasts a considerable static load rating C0 and dynamic load capacity C, reflecting its robustness and durability under various working conditions. As part of Bosch Rexroth’s ball screw assemblies accessories range, this bearing contributes significantly to the overall system's precision and reliability. Overall, the BEARING LAN-B-A 17 is an integral component that enhances the performance of ball screw assemblies across numerous applications due to its construction quality, static and dynamic load capabilities, as well as its contribution to system rigidity.
