The Bosch Rexroth BEARING LAF-B-Z 12 (R159001200) is a high-quality fixed bearing unit designed to provide reliable support and precise guidance for ball screw assemblies. This bearing is part of the assembly group LAF and is suitable for screw end types A, B, C, D, E, and F. It features an angular contact thrust ball bearing LGF and comes with a slotted nut NMA or NMZ for secure fastening. The BEARING LAF-B-Z 12 is engineered to handle both dynamic and static loads efficiently. Its dynamic load capacity C and static load capacity Co are determined by Bosch Rexroth's general technical notes and information for bearings. The rigidity against tilting (Rkl) and the axial rigidity (RFB) ensure that the bearing maintains its performance even under varying loads and conditions. The outer diameter D and size d are specified to fit precisely with compatible components. This bearing unit has been designed with a specific number of mounting holes, which facilitates ease of installation while the hole pattern BB ensures compatibility with the corresponding ball screw assembly. The bearing's frictional torque with seal MRb contributes to a smooth operation while minimizing resistance. As part of the accessories for Rexroth ball screw assemblies, this fixed bearing supports applications requiring high precision and rigidity. The double-thrust, screw-down series LGFB, LGFA, and LGFC further enhance its versatility in various configurations. Overall, the Bosch Rexroth BEARING LAF-B-Z 12 (R159001200) represents a robust solution for applications demanding high precision linear movement. Its design ensures long-lasting performance while maintaining the quality expected from Bosch Rexroth's range of engineering components.
