Thrust roller bearings are designed to support both axial and radial loads, with the restriction that radial loads should not exceed 55% of the axial loads.
Compared to other thrust roller bearings, this type has a lower friction coefficient, higher speeds, and better self-aligning performance.
Product Features
The 29000 type bearing roller is an asymmetrical spherical roller that reduces relative sliding between the roller and raceway during operation. It boasts a long length, large diameter, high number of rollers, and high load capacity.
Lubrication with oil is typically used, and lubrication with grease is acceptable for low speeds. When designing and selecting, preference should be given to 80000 thrust cylindrical roller bearings, 90000 thrust tapered roller bearings, and AXK thrust needle bearings, which can withstand one-way axial loads.
These bearings have a higher axial load capacity compared to thrust ball bearings, while also being more rigid and occupying less axial space. Both thrust cylindrical roller bearings and thrust tapered roller bearings are suitable for low-speed applications, with the latter having a slightly higher rotational speed.
Thrust cylindrical roller bearings are individual components that can withstand only unidirectional axial loads and light impacts. They can restrict the axial movement of the shaft (or housing) in one direction and thus be used for unidirectional axial positioning.
However, their load-bearing capacity is significantly greater than that of thrust ball bearings.
When the rollers rotate, they may slip on the raceway of the ferrule due to different linear speeds at each end of the roller.
As a result, the limit speed of these bearings is lower compared to that of thrust ball bearings and they are typically only suitable for low-speed applications.
The standard design of thrust cylindrical roller bearings features a metal solid cage made for vehicles. Other cage types or materials can be used to meet the user’s requirements.
Thrust tapered roller bearings can only handle unidirectional axial loads and can limit the axial movement of the bearing in one direction, making them useful for unidirectional axial positioning.
Compared to thrust cylindrical roller bearings, these bearings have a higher load-bearing capacity and less relative sliding, but a lower limit rotational speed.
Application
Thrust cylindrical roller bearings are primarily utilized in heavy machinery, high-power marine gearboxes, oil rigs, vertical motors, and other types of machinery.
