The Bosch Rexroth PILLOW BLOCK (R159112020) is a high-precision pillow block unit designed for robust performance and reliability. This unit is part of the assembly group SEBF and comes in size 20, tailored to meet the needs of various applications requiring precise linear motion. The pillow block unit includes a precision-engineered steel housing with reference edges on both sides, ensuring accurate alignment and mounting. Incorporated within the housing is an angular contact thrust ball bearing LGN, which is known for its capacity to handle combined loads with high axial rigidity. The PILLOW BLOCK SEB-F-Z 20 also features a slotted nut, either NMA or NMZ, and threaded rings GWR for secure fastening and easy adjustments. It is designed to be compatible with screw ends in Forms A, B, C, D, and E, providing versatility for different screw end specifications. The product belongs to the dynamic load capacity C class and has been rated for both dynamic and static axial load capacities. This ensures that it can support varying loads while maintaining precision. Size specifications such as V (nominal size), d (size), H (size), SW (size), H1 (size), S (size), along with the tightening torque values are meticulously engineered to ensure optimal performance in demanding applications. The static load rating C0 provides an indication of the maximum stationary load that the pillow block can withstand. This Bosch Rexroth pillow block unit also comes equipped with accessories suitable for Rexroth ball screw assemblies, enhancing its utility in a wide range of linear motion systems. With a weight of only 0.2 kg, it offers a lightweight yet durable solution for linear movement requirements in various machines and equipment setups. Its fixed bearing design with angular contact thrust ball bearings LGFB or LGFC further emphasizes its capability to maintain stability under high axial loads while facilitating smooth motion control.
