Thrust roller bearings play a critical role in various industrial applications, especially in situations where heavy loads and impact loads need to be borne. These barings are specifically designed to primarily bear axial loads, but they can also handle radial loads to a certain degree.
The construction of thrust roller bearings generally consists of bearing seats, shaft rings, rollers and cages. Out of these components, rollers are considered the core parts of the bearings. They are positioned between the bearing seats and shaft rings, and their rolling motion transmits and disperses axial loads. This unique design allows thrust roller bearings to maintain a low friction coefficient while carrying heavy loads, which reduces energy loss and contributes to the longevity of the bearing.
Thrust roller bearings are specially designed to carry axial and radial combined loads, mainly axial loads, and can withstand large axial loads. This feature makes them suitable for use in heavy load and shock load environments. In addition, they also come with several other notable features:
Model | Inner diameter | Outer diameter | Height |
---|---|---|---|
81114 | 70mm | 95mm | 18mm |
81214 | 70mm | 105mm | 27mm |
81115 | 75mm | 100mm | 19mm |
Thrust roller bearings are extensively utilized in numerous industrial fields due to their ability to withstand both axial and radial combined loads, mainly axial loads. The following is a comprehensive description of the application of thrust roller bearings:
Thrust roller bearings are widely used in heavy machinery and equipment like oil drilling rigs and iron and steel machinery, where they must endure high loads and impact loads. Thrust cylindrical roller bearings, for example, are highly suited to oil drilling rigs and iron and steel machinery. In hydraulic generators and vertical motors, thrust spherical roller bearings play an essential role in withstanding significant axial forces and overturning moments. Thrust roller bearings also assist in supporting and transmitting loads in ship propeller shafts. Finally, they are crucial in tower cranes and extruders, both of which are characterized by heavy loads and impact loads.
Specifically, thrust tapered roller bearings are advantageous in situations such as crane hooks that demand the ability to withstand unidirectional axial loads.
In ship transmission systems, thrust roller bearings are a popular bearing that effectively resolves the issue of large thrust loads.
In car parts like the gearbox and rear axle, thrust roller bearings are used to endure enormous thrust and radial loads to guarantee the car's proper functioning.
