It has double - row rollers. The outer ring has a common spherical raceway, while the inner ring has two raceways that are inclined at an angle relative to the bearing axis. This structure endows it with automatic self - aligning performance. It is not easily affected by the angular alignment error between the shaft and the bearing housing or shaft bending. It can automatically adjust the misalignment caused by shaft or housing deflection or misalignment, making it suitable for applications where installation errors or angular errors due to shaft deflection occur.
The inner bore comes in two types: cylindrical and conical. The taper of the conical bore is either 1:30 or 1:12. Bearings with a conical inner bore, when paired with an adapter sleeve or a withdrawal sleeve, can be conveniently and quickly assembled on a plain shaft or a stepped machine shaft.
Thanks to its excellent self - aligning performance, it can operate stably under complex conditions such as shaft deflection and misalignment. This significantly enhances the stability and reliability of equipment operation, reduces abnormal wear and failures caused by misalignment issues, and extends the service life of the equipment.
It has a strong ability to bear radial and bidirectional axial loads, enabling it to handle various heavy - load and impact - load working environments. It meets the strict load - bearing requirements of components in large - scale mechanical equipment and heavy - duty industrial equipment.
It is widely used in equipment such as rolling machinery in mining plants, ore extraction and beneficiation plants, gas turbines in power plants, mechanical equipment in motor factories, rolling mills in the metallurgical industry, as well as various crushers and ceramic machinery. The equipment in these industries usually operates under harsh conditions, facing heavy loads, impact loads, and adverse working environments. The high load - bearing capacity, impact resistance, and good self - aligning performance of spherical roller bearings ensure the stable and reliable operation of the equipment.
It plays an important role in manufacturing equipment such as paper - making machinery, printing machinery, wood - working machinery, plastic and chemical fiber machinery, textile machinery, food industry equipment, and pharmaceutical equipment. These industries have high requirements for the precision, stability, and reliability of equipment. Spherical roller bearings can meet these needs, ensuring the smooth progress of the production process and the stability of product quality.
It is used in components such as the axles of railway vehicles, bearing various loads during vehicle operation and providing guarantee for the safe and stable operation of the vehicle.
