The Bosch Rexroth BEARING LAF-B-Z 17 (R159001700) is a high-precision fixed bearing unit specifically designed for ball screw assemblies. This robust bearing is part of the assembly group LAF and is suitable for a wide range of screw end types, including A, A, A, A, A, and A. It incorporates an angular contact thrust ball bearing from the LGF series which ensures excellent load handling capabilities. This model boasts an impressive dynamic load capacity (C) and static load capacity (Co), providing reliable performance under various loading conditions. The detailed technical notes and project planning information available for this bearing indicate its suitability for high-demand applications where precision and durability are paramount. With a focus on minimizing tilting rigidity (Rkl) and maximizing the axial rigidity of the bearing (RFB), the BEARING LAF-B-Z 17 ensures consistent operation and longevity. The outer diameter (D), size (d), minimum number of mounting holes, hole pattern (BB), and mounting holes dimensions (t) are all precisely engineered to facilitate easy installation and secure fitting in complex machinery. The bearing also features a slotted nut from either the NMA or NMZ series, contributing to its overall stability and performance. Its nominal size allows it to be easily integrated into existing systems without extensive modifications. Additionally, this model takes into account operational parameters like limit speed with grease (nmax), ensuring it can operate effectively within the required rotational speed range. The frictional torque with seal (MRb) has been calculated to ensure smooth operation while preventing unnecessary wear. As part of Bosch Rexroth's commitment to providing comprehensive solutions for linear motion technology, this fixed bearing is compatible with accessories for Rexroth ball screw assemblies. It stands out as a durable component that maintains its integrity even in demanding industrial environments.
