  2. Spiral groove bearing - Wikipedia

    en.wikipedia.org/wiki/Spiral_groove_bearing

    Spiral groove bearings were used most successfully in inertial gyroscopes for planes and ships. [9] In this application, the spiral groove bearings were made of boron carbide ceramic and the grooves were manufactured by ION beam. The bearings were very successful, with MTBF values over 100,000 hours and stop-start capability of 1,000,000 times ...

  3. Rolling-element bearing - Wikipedia

    en.wikipedia.org/wiki/Rolling-element_bearing

    The updated model offers life calculations also for hybrid bearings, i.e. bearings with steel rings and ceramic (silicon nitride) rolling elements. [21] [22] Even if the 2019 GBLM release was primarily developed to realistically determine the working life of hybrid bearings, the concept can also be used for other products and failure modes.

  6. Jewel bearing - Wikipedia

    en.wikipedia.org/wiki/Jewel_bearing

    A jewel bearing is a plain bearing in which a metal spindle turns in a jewel-lined pivot hole. The hole is typically shaped like a torus and is slightly larger than the shaft diameter. The jewels are typically made from the mineral corundum , usually either synthetic sapphire or synthetic ruby .

  7. Ceramic forming techniques - Wikipedia
