The Bosch Rexroth BEARING LAN-B-Z 12 (R159011200) is a precision-engineered fixed bearing unit designed to provide high rigidity and load capacity for ball screw assemblies. This bearing is part of the assembly group LAN, size 12, and is specifically suitable for screw end types A, ensuring compatibility with a range of applications. The unit includes an angular contact thrust ball bearing LGN and a slotted nut, either NMA or NMZ, which together enhance the bearing's performance in terms of load distribution and axial rigidity. Key specifications of the BEARING LAN-B-Z 12 include its dynamic load capacity (C), which must be referenced against general technical notes for accurate application planning. The static load rating (C0) and dynamic load capacity (C) are critical factors in determining the bearing's suitability for specific project requirements. Additionally, it features a high limit speed for grease lubrication (nmax), which indicates the maximum rotational speed at which the bearing can operate effectively. The outer diameter (D) and size (d) dimensions ensure that this fixed bearing can be integrated seamlessly into existing setups. Furthermore, it exhibits a low frictional torque with seal (MRb), minimizing energy loss and heat generation during operation. This Bosch Rexroth fixed bearing also boasts significant rigidity against tilting (Rkl) as well as axial rigidity (RFB), both essential for maintaining stability under varying loads. As part of Rexroth's ball screw assembly accessories, this product enhances overall system performance while maintaining a compact form factor. Its weight is optimized to contribute to the efficiency of the machinery without compromising on strength or durability.
