PRODUCT DETAILS :

The structure features of Spherical Roller Thrust Bearings:

This bearings have self aligning function, strong axial bear ability, does not be affected by the installation error and the deflection of shaft.

Regard to the self aligning function, different structure have different self aligning angles, generally speaking, the self aligning angle is not more than 3 degrees. The higher axial load is, the smaller self aligning angle is allowed.

Spherical Roller Thrust Bearings mainly be applied to hydro generator, die casting machine, marine diesel engine, reducer etc.



Spherical roller thrust bearings

Spherical roller thrust bearings be pushed into thrust roller bearings should be rotated without a sense of flexibility. If the obvious rotation is not flexible, then the shaft size is too large, tolerances to be reduced. Spherical roller thrust bearings pressed into the shaft after the rotation of a significant voice, it may be too much shaft tolerance or shaft roundness is not good. So in the control of shaft and thrust roller bearing chamber tolerance must also control the roundness. Because the spherical roller thrust bearings are high precision products, such as improper assembly can easily damage the spherical roller thrust bearing channel, resulting in spherical roller thrust bearing damage. Spherical roller thrust bearings in the assembly should have a dedicated use of the mold, not knocking damage, the pressure can only be a small circle into the pressure, the pressure can only be a large circle of large circle stress. Assembly requires the use of pressure or hydraulic pressure in the upper and lower mold outside the horizontal state, if tilt will lead to thrust roller bearing channel damage due to stress, leaving the thrust roller bearing guide ring. Spherical roller thrust bearings installed in the rotor to make dynamic balance is easy to move the iron balance generated when the ball into the spherical roller thrust bearings inside, it is best to install spherical roller thrust bearings before the balance. If the oil or grease in the spherical roller thrust bearing chamber to stay more, when the spherical roller thrust bearing rotation is easy along the shaft into the spherical roller thrust bearings. Spherical roller thrust bearing chamber is best not to be oiled or greased, if not coated, then control should not be in the thrust roller bearing indoors have to stay. : Spherical roller thrust bearings and spherical roller thrust bearings for low speed applications, spherical roller thrust bearings slightly higher than the speed of spherical roller thrust bearings. Spherical roller thrust bearings are separable bearings, can only withstand one way axial load and slight impact, can limit the shaft (or housing) in one direction of axial displacement, it can be used as a one way axial positioning. But its carrying capacity is far greater than the thrust ball bearings. Roller rolling, due to the different speeds at both ends of the roller so that the roller in the raceway inevitably slip, so the limit speed of these bearings than the thrust ball bearings, usually only suitable for low-speed operation occasions.

Standard design of spherical roller thrust bearings made of metal body cage, according to user requirements, but also the use of other types or materials of the cage. Spherical roller thrust bearings can only withstand one way axial load, can limit the axial displacement of the bearing one way, it can be used as a one way axial positioning.
