Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads.
Compared with other thrust roller bearings, this type of bearing has lower friction factor, higher speed and self-aligning performance.
The roller of the 29000 type bearing is an asymmetrical spherical roller, which can reduce the relative sliding of the roller and the raceway during work.
And the roller is long, the diameter is large, the number of rollers is large, and the load capacity is high.
It is usually lubricated with oil and can be lubricated with grease at individual low speeds.
When designing and selecting, it should be preferred;
80000 thrust cylindrical roller bearings, 90000 thrust tapered roller bearings and AXK thrust needle bearings can withstand one-way axial loads.
It has much greater axial load capacity than thrust ball bearings and is rigid and takes up less axial space.
Thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low speed applications.
Thrust tapered roller bearings have a slightly higher rotational speed than thrust cylindrical roller bearings.
Thrust cylindrical roller bearings are separate bearings that can only withstand one-way axial loads and slight impacts, and can limit the axial displacement of the shaft (or casing) in one direction, so it can be used as one-way axial positioning.
However, its carrying capacity is much larger than that of thrust ball bearings.
When the roller rolls, the roller will inevitably slip on the ferrule raceway due to the different linear speeds at both ends of the roller.
Therefore, the limit speed of such bearings is lower than that of thrust ball bearings and is usually only suitable for low speed applications.
The standard design of the thrust cylindrical roller bearing adopts the metal solid cage of the vehicle, and other types or materials of the cage can be used according to the user’s requirements.
Thrust tapered roller bearings can only bear one-way axial load and can limit the axial displacement of the bearing in one direction, so it can be used as one-way axial positioning.
Compared with the thrust cylindrical roller bearing, the bearing capacity is large and the relative sliding is small, but the limit rotation speed is low.
Thrust cylindrical roller bearings are mainly used in heavy machinery, high power marine gearboxes, oil rigs, vertical motors and other machinery.
