  2. Thrust bearing - Wikipedia

    en.wikipedia.org/wiki/Thrust_bearing

    A thrust bearing is a particular type of rotary bearing. Like other bearings they permanently rotate between parts, but they are designed to support a predominantly axial load. [1] Thrust bearings come in several varieties. Thrust ball bearings, composed of bearing balls supported in a ring, can be used in low-thrust applications where there is ...

  3. Spherical roller thrust bearing - Wikipedia

    en.wikipedia.org/.../Spherical_roller_thrust_bearing

    A spherical roller thrust bearing is a rolling-element bearing of thrust type that permits rotation with low friction, and permits angular misalignment. The bearing is designed to take radial loads, and heavy axial loads in one direction. Typically these bearings support a rotating shaft in the bore of the shaft washer that may be misaligned in ...

  4. Spiral groove bearing - Wikipedia

    en.wikipedia.org/wiki/Spiral_groove_bearing

    Flat thrust bearings, the most common spiral groove bearings, are so named because one consists of a flat surface that opposes the grooved surface. Variations in this type of bearing come from the nature of the spiral surface and the type of fluid flow. The following is a list of the different types of flat thrust bearings: With transverse flow

  5. Tapered roller bearing - Wikipedia

    The cup is simply the outer ring. Internal clearance is established during mounting by the axial position of the cone relative to the cup, although preloaded installations without clearance are common. Metric tapered roller bearings follow the designation system defined by ISO 355.

  6. Rolling-element bearing - Wikipedia

    The third character is the radial clearance, which is normally defined by a number between 0 and 9 (inclusive), in ascending order, however for radial-thrust bearings it is defined by a number between 1 and 3, inclusive. The fourth character is the accuracy ratings, which normally are, in ascending order: 0 (normal), 6X, 6, 5, 4, T, and 2.

  7. Thrust block - Wikipedia

    en.wikipedia.org/wiki/Thrust_block

    The thrust box was built of a box-like cast iron housing with a radial bearing at each end and a number of collars formed on the shaft between them. [3] This shaft was often a short section of removable shaft called the thrust shaft , linking the engine ahead to the propeller shaft astern.

  8. Components of jet engines - Wikipedia

    en.wikipedia.org/wiki/Components_of_jet_engines

    It provides cooling air to the turbines, airflow into bearing cavities to prevent oil flowing out and cavity pressurization to ensure rotor thrust loads give acceptable thrust bearing life. Air, bled from the compressor exit, passes around the combustor and is injected into the rim of the rotating turbine disc.

  9. Spherical roller bearing - Wikipedia

    en.wikipedia.org/wiki/Spherical_roller_bearing

    Spherical roller bearing with a brass cage in a cut-through view. A spherical roller bearing is a rolling-element bearing that permits rotation with low friction, and permits angular misalignment. Typically these bearings support a rotating shaft in the bore of the inner ring that may be misaligned in respect to the outer ring.
