The SKF 51107 is a single-direction thrust ball bearing with a 35mm inner diameter, 52mm outer diameter, and 12mm thickness. Made of GCr15 high-carbon chromium steel with a pressed steel cage, it withstands unidirectional axial loads only. Ideal for low-speed, high-precision axial positioning applications (e.g., machine tool lead screws, heavy machinery axial supports, automation equipment adjustment mechanisms), it offers a compact design, high axial rigidity, and resistance to moderate impacts.
