The Bosch Rexroth BEARING LAF-B-A 30 (R159003030) is a high-precision, fixed bearing unit designed for use with ball screw assemblies. This robust bearing is part of the LAF assembly group and is specifically engineered to support screw end types A, B, C, D, E, and F. It features an angular contact thrust ball bearing LGF that ensures reliable axial support and load capacity. The inclusion of a slotted nut, either NMA or NMZ, allows for secure fastening and easy installation. This bearing unit boasts impressive technical specifications including a dynamic load capacity (C) and static load capacity (C0), which are detailed in the general technical notes and information provided by Bosch Rexroth. Users can expect excellent rigidity against tilting (Rkl) as well as axial rigidity (RFB), ensuring stable operation even under demanding conditions. The BEARING LAF-B-A 30 has been designed with a specific outer diameter (D) and size (d), as well as a minimum number of mounting holes (t) to facilitate versatile mounting options. The unit's limit speed for grease lubrication (nmax) indicates its capability to operate at high speeds while maintaining performance and longevity. Additionally, the bearing frictional torque with seal (MRb) provides insight into the expected rotational resistance during operation. As part of the accessories available for Rexroth ball screw assemblies, this bearing unit contributes to the overall efficiency and precision of motion control applications. The weight specification further aids in project planning by allowing designers to consider the impact on system dynamics. In summary, the Bosch Rexroth BEARING LAF-B-A 30 is a durable and precise fixed bearing solution suitable for a variety of applications requiring reliable linear motion support. Its design features ensure it meets rigorous performance standards while offering ease of integration into existing systems.
