Characteristic and Application of Thrust spherical roller

Characteristic and Application of Thrust spherical roller bearing

Sep 01, 2021

Thrust spherical roller bearings are roughly the same as self-aligning roller bearings. The raceway surface of the seat is a sphere centered at the same point on the bearing central shaft. The bearings of this kind are spherical, so they have the function of automatic self-aligning and are not sensitive to coaxiality and shaft deflection.

  Different from other thrust bearings, this kind of bearing has a very large axial load capacity, and can bear several radial loads while bearing axial loads, but the radial load shall not exceed 55% of the axial load.

  As long as the loads P and P0 do not exceed 0.05c0 and the ring rotates, the bearing allows the aligning angles listed in the table below.

  Bearing diameter series Self-aligning Angle Bearing diameter series self-aligning Angle 200 series 1°~1.5° 300 series 1.5°~2° 400 series 2°~3° Small values are suitable for larger bearings, and the allowable self-aligning Angle will decrease as the load increases.

  Oil lubrication is generally used when using.

  This kind of bearing is mainly used in oil drilling machine, iron and steel making machinery, hydraulic generator, vertical motor, ship propeller shaft, tower crane, extruder and so on.
