The Bosch Rexroth PILLOW BLOCK (R159111020) is a meticulously engineered pillow block unit designed to facilitate the support and guidance of ball screw assemblies. This unit is part of the assembly group SEBF, which is distinguished by its precision pillow block housing crafted from robust steel, featuring reference edges on both sides for enhanced accuracy during installation. The unit incorporates an angular-contact thrust ball bearing LGN that ensures reliable performance under axial load conditions. Additionally, the PILLOW BLOCK comes with a slotted nut, either NMA or NMZ, and threaded rings GWR to secure and adjust the bearing within its housing. The product is versatile, designed to accommodate screw ends in Forms A1 to A5, making it suitable for various installation requirements. It boasts a dynamic load capacity (C) and static load rating (C0), which are indicative of its ability to handle varying loads with efficiency and stability. The dimensions of this pillow block unit include a size V for the product group ID and various sizes for other components such as d, H1, SW, H2, ensuring compatibility with different setups. The specified tightening torque ensures that the components can be securely fastened without compromising structural integrity. As an accessory for Rexroth ball screw assemblies, this pillow block unit is not only functional but also designed with precision in mind. Its weight is calibrated to maintain balance in applications where it's deployed. With its nominal size parameters clearly defined, this Bosch Rexroth PILLOW BLOCK stands out as a reliable fixed bearing solution equipped with an angular-contact thrust ball bearing LGFB or LGFC for high-performance applications requiring precise linear movement and support.
