The Bosch Rexroth BEARING LAN-B-Z 20 (R159012000) is a high-precision assembly group bearing unit designed for robust performance and reliability. This fixed bearing unit incorporates an angular contact thrust ball bearing LGN, known for its excellent axial load handling capabilities. It is accompanied by a slotted nut, either NMA or NMZ, ensuring secure fastening and operational stability. The bearing is compatible with screw end types A, further highlighting its versatility in application. With a dynamic load capacity C and a static load capacity C, the BEARING LAN-B-Z 20 ensures durability under varying operational loads, as indicated in the general technical notes and information for bearings provided by Bosch Rexroth. The rigidity against tilting (Rkl) and the axial rigidity (RFB) of the bearing contribute to its ability to maintain stability and precision in demanding applications. The nominal size of the bearing allows for integration into various machine designs without compromising on space or efficiency. Additionally, the product's limit speed with grease lubrication (nmax), outer diameter (D), size (d), and frictional torque with seal (MRb) are critical specifications that ensure optimal performance within intended operational parameters. This particular model is part of the LAN series of bearings from Bosch Rexroth, which includes accessories tailored for Rexroth ball screw assemblies. The double thrust design can be found in series LGNB, LGNA, and paired double thrust bearings in series LGNC, indicating a range of configurations to suit different application needs. The weight specification denotes its lightweight nature relative to its nominal size, emphasizing ease of installation without sacrificing strength or functionality. In summary, the Bosch Rexroth BEARING LAN-B-Z 20 leverages advanced engineering to deliver a reliable fixed bearing solution suitable for high-precision applications requiring robust axial support and consistent performance.
