Introduction of SKF Thrust Spherical Roller Bearings

SKF Thrust spherical roller bearings are roughly the same as spherical roller bearings. The raceway surface of the race is a spherical surface centered on the same point on the central axis of the bearing. The rollers of this type of bearing are spherical, so it has self-aligning Function, not very sensitive to coaxiality and shaft deflection.

Thrust spherical roller bearings are divided into symmetrical thrust spherical roller bearings and asymmetrical thrust spherical roller bearings

Unlike other thrust bearings in the catalog, this type of bearing has a very large axial load capacity. It can also withstand a number of radial loads while bearing axial loads, but the radial load must not exceed 55% of the axial load.

As long as the loads P and P0 do not exceed 0.05C0, and the shaft ring rotates, the bearing allows the alignment angle listed in the following table.

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 allowable when the load increases The centering angle will decrease.

Oil lubrication is generally used when in use.

Thrust tapered roller bearings can only bear one-way axial load and can limit the one-way axial displacement of the bearing, so it can be used for one-way axial positioning. Compared with thrust cylindrical roller bearings, the bearing capacity is large, the relative sliding is small, but the limit speed is lower.
