The SKF 51110 is a single-direction thrust ball bearing with a 50mm inner diameter, 70mm outer diameter, and 14mm 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., large machine tool lead screws, mining machinery axial supports, heavy equipment adjustment mechanisms), it offers a compact design, high axial rigidity, and resistance to strong impacts.
