The Bosch Rexroth PILLOW BLOCK (R159111220) is a high-precision component designed for use in linear motion and positioning applications. This pillow block unit features a robust steel housing with reference edges on both sides, ensuring accurate alignment and stable mounting. Incorporated within the unit is an angular contact thrust ball bearing LGN, which is designed to handle both axial and radial loads effectively, promoting smooth motion and enhancing the overall system rigidity. The unit includes a slotted nut, either NMA or NMZ, along with threaded rings GWR for secure attachment and easy adjustment. The PILLOW BLOCK SEB-F-Z 12 is engineered to accommodate screw ends of Forms A, B, C, D, E, and F, making it versatile for various applications and compatible with multiple screw end types. With its dynamic load capacity (C) and static load rating (C0), the pillow block can withstand significant operational stresses while maintaining performance. The accessory's size specifications such as V (nominal size), d (size), H1 (size), SW (size), H2 (size), S1 (size), along with the specified tightening torque values ensure that users can select the appropriate model for their specific requirements. This pillow block unit is part of Bosch Rexroth's product group ID SEBF and comes in size 12. It is an essential accessory for Rexroth ball screw assemblies and contributes to their efficiency by providing reliable support. The weight of the unit is optimized to contribute to the overall machinery without sacrificing strength or precision. Overall, the Bosch Rexroth PILLOW BLOCK SEB-F-Z 12 offers a combination of durability, precision engineering, and adaptability, suitable for high-performance linear motion systems where accuracy and reliability are paramount.
