The Bosch Rexroth BEARING LAF-B-Z 20 (R159002000) is a high-precision bearing unit designed for use in various mechanical and industrial applications. Part of the assembly group bearing unit LAF, this product features a size 20 angular contact thrust ball bearing LGF, which is known for its capability to handle combined loads with high axial rigidity. The fixed bearing configuration includes a slotted nut, either NMA or NMZ, ensuring secure fastening and compatibility with screw end types A. This bearing unit is engineered to provide superior support and stability to ball screw assemblies, with its dynamic load capacity C and static load capacity C ensuring optimal performance under varying load conditions. The rigidity against tilting (Rkl) and the axial rigidity (RFB) specifications highlight the product's ability to maintain stiffness and resist deformation under stress. Additionally, the limit speed for grease lubrication (nmax), outer diameter (D), and size (d) are indicative of the bearing's design for high-speed applications while maintaining precision. The BEARING LAF-B-Z 20 comes equipped with a specific number of mounting holes, facilitating ease of installation and integration into existing systems. The mounting holes (t) are strategically placed for robust attachment. Moreover, the bearing frictional torque with seal (MRb) indicates low resistance during operation, contributing to energy-efficient performance. As an accessory for Rexroth ball screw assemblies, this fixed bearing with angular contact thrust ball bearing LGF is part of the LGFB, LGFA, and LGFC series. These series are characterized by their double-thrust screw-down design that enhances load handling capabilities. The weight specification reflects its solid construction without compromising on system weight considerations. Overall, the Bosch Rexroth BEARING LAF-B-Z 20 is a versatile component that offers reliability and precision for demanding applications where robustness and accurate movement control are essential.
