What Is A Thrust Roller Bearing?

Thrust Roller Bearing

        Thrust roller bearing is used to bear axial load mainly shaft, radial combined load, but the radial load shall not exceed 55% of the axial load. Compared with other thrust roller bearings, such bearings have a lower friction factor, higher speed, and have the ability to align.

         The bearing’s shaft ring, seat ring and rolling body are separated and can be loaded and unloaded separately.

        thrust bearing types: thrust spherical roller bearings, thrust cylindrical roller bearings, thrust tapered roller bearings and thrust needle roller bearings.

Thrust roller bearing Related matters
         1.room tolerance selection and control: thrust roller bearing pressed into the thrust roller bearing should rotate flexibly without blocking feeling.  If there is obvious rotation inflexibility, it indicates that the size of the shaft is too large and the tolerance should be adjusted downward.

        If the roller bearing pressed into the shaft after the hand rotation has obvious “rustle” feeling, it may be too large shaft tolerance or shaft roundness is not good. So in the control of the shaft and thrust  bearing room tolerance should also control the roundness, many domestic manufacturers only on the tolerance control, no control of roundness.
          2, Bearing assembly method: because the thrust roller bearing is a high-precision products, such as improper assembly is easy to cause damage to the thrust roller bearing groove, resulting in damage to the thrust roller bearing.  in the assembly should have a special mold, can not be randomly knocked, in the press into the shaft can only be small circle force, press the large circle can only be large circle force.

          Assembly requires the use of air pressure or hydraulic pressure, in the pressure of the upper and lower die to outside the horizontal state, such as tilt will lead to thrust roller bearing groove due to force damage, and make thrust roller bearings produce guide ring.
         3, Assembly method: thrust  bearing in the installation to the rotor to do dynamic balancing is easy to dynamic balancing when the generated iron chips into the thrust roller bearing internal, so it is best to install thrust roller bearing before doing dynamic balancing.

         4.There are some manufacturers in order to facilitate the assembly, assembly in the  roller bearing room coated with some oil or grease lubrication effect, but often the operator is difficult to control the amount of good, if the oil or grease in the thrust bearing room accumulate more, in the thrust roller bearings rotation is easy along the shaft into the thrust roller bearing inside. Thrust roller bearing room is best not to apply oil or grease, such as non-coating can not be controlled in the thrust roller bearing room there is no accumulation.
        5. Prevention of bearing paint rust: varnish rust is characterized by more in the sealed motor, the motor in the assembly sound is very good, but in the warehouse after some time, the motor noise becomes very large, remove the thrust roller bearings have serious rust phenomenon. Many manufacturers used to think that it is the problem of thrust roller bearing, after our continuous publicity, the motor factory has realized that it is mainly the problem of insulating paint.

          6.The problem is mainly because the insulating paint volatile acid in a certain temperature, humidity to form corrosive substances, the thrust roller bearing groove corrosion leads to damage to the thrust roller bearings. The problem can only be good insulating paint, and after drying ventilation after a period of assembly
Thrust roller bearing characteristics.
       1. 29000 type bearing stick for asymmetric spherical roller, can reduce the roller and raceway in the work of the relative sliding, and roller long, large diameter, the number of rollers, high load capacity, usually using oil lubrication, individual low-speed case available grease lubrication. In the design selection, should be preferred.
       2. 80000 type thrust cylindrical roller bearings, 90000 type thrust tapered roller bearings and thrust needle roller bearings, can withstand one-way axial load, it is much larger than the axial load capacity of thrust ball bearings, and rigid, occupy little axial space.
       3.Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low speed occasions, and the speed of thrust tapered roller bearings is slightly higher than that of thrust cylindrical roller bearings.

        4.Thrust cylindrical roller bearing is a separation type bearing, can only withstand one-way axial load and slight impact, can limit the shaft (or shell) a direction of axial displacement, so can be used as a one-way axial positioning. But its bearing capacity is much larger than the thrust ball bearing. Roller rolling, due to the roller ends of the line speed is different, so that the roller in the ring raceway inevitably produce sliding, therefore, the limit speed of such bearings than thrust ball bearings low, usually only for low-speed operation occasions.
     5.   The standard design of thrust cylindrical roller bearings use the metal solid cage, according to user requirements, can also use other types or materials of cage. Thrust tapered roller bearings can only withstand one-way axial load, can limit the bearing one-way axial displacement, so can be used as a one-way axial positioning. Compared with the thrust cylindrical roller bearings, the bearing capacity is large, the relative sliding is small, but the limit speed is low.
Thrust  bearing applications
       Thrust cylindrical roller bearings are mainly used in heavy machine tools, high-power marine gearboxes, oil drilling rigs, vertical motors and other machinery
       Thrust spherical roller bearings are mainly used in oil drilling rigs, iron and steel making machinery, hydraulic generators, vertical motors, propeller shafts for ships, tower cranes, extruders, etc
