The Bosch Rexroth BEARING LAF-C-A 30 (R159033030) is a high-precision fixed bearing unit from their assembly group LAF, size 30. This robust bearing is designed to provide exceptional support and stability for ball screw assemblies, ensuring smooth and accurate motion in demanding applications. It is equipped with an angular contact thrust ball bearing LGF, which cannot be purchased separately, and comes with a slotted nut NMA or NMZ for secure fastening. The bearing is suitable for screw end types A to A6, making it versatile for various configurations. This fixed bearing unit boasts impressive specifications that enhance its performance in operation. It has a static load rating C0 and dynamic load capacity C that ensure its capability to withstand both stationary and dynamic forces efficiently. The outer diameter D of the bearing allows for compatibility with corresponding components, while the size d ensures a proper fit within the assembly. The BEARING LAF-C-A 30 features a minimum number of mounting holes to facilitate easy installation, and the hole pattern BB aids in precise alignment during assembly. The rigidity against tilting Rkl highlights its ability to maintain stability under tilting loads, contributing to the overall precision of the mechanism it supports. Additionally, it has a specified limit speed for grease lubrication nmax that ensures optimal performance at safe rotational speeds. The bearing's frictional torque with seal MRb is kept low to minimize resistance during operation, thereby enhancing efficiency. Moreover, the axial rigidity RFB of the bearing contributes to its ability to maintain position without significant deflection under axial loads. Accessories available for this unit are tailored for Rexroth ball screw assemblies, ensuring seamless integration into existing systems. Lastly, the weight of this fixed bearing unit is carefully calibrated based on its nominal size x x , which contributes to the overall mass of the assembly without compromising performance.
