Spherical Roller Thrust Bearings

Spherical Roller Thrust Bearing -- The rolling elements are barrel-shaped and the raceways closely resemble the cone-and-cup design found in standard tapered roller bearings. This provides the bearing with self-aligning capabilities which is beneficial in applications where shaft deflection or shock loads can occur. They support heavy axial thrust in one direction (though variants exist for both directions), and can also tolerate moderate radial loads. As with tapered roller thrust bearings, the angle between the roller axis and the bearing axis determines the ratio of axial/radial loading.

Spherical roller thrust bearings are self-aligning, making them unaffected by mounting errors and shaft deflection. The E-type uses an even higher load capacity design featuring a pressed steel cage. We recommend machined brass cages for horizontal shafts and high-speed applications.

As these bearings have many parts that are hard to reach with grease, oil lubrication is used even at low speeds. Cages are typically made from machined brass.

Features

  • Correct for misalignment
    The spherical raceway surface of the housing washer makes spherical roller bearings self-aligning.
  • High load capacity
    Spherical roller bearings offer high axial load capacity, with some capacity for radial load when axial load is applied.

Applications

  • Air preheaters, extruders, injection molders, excavators, cranes
