Thrust roller bearings have three common types: thrust cylindrical roller bearings, thrust tapered roller bearings, and thrust spherical roller bearings. These three types of bearings are related but also different.
In industrial, thrust roller bearings are produced for those machines that need to withstand axial loads (thrust loads). When supporting axial force, the thrust roller bearing can reduce friction during machinery operation.
The thrust cylindrical roller bearing is one of the most basic thrust bearings. It has a simple internal design with rollers, inner rings, outer rings, cages, etc. When subjected to high axial bearings, the thrust cylindrical roller bearing performs well, because its rollers are cylindrical and form linear contact with the raceways.
Thrust cylindrical roller bearings have less friction compared with other thrust bearings, so they are widely used in high-speed mechanical equipment. Besides, the cylindrical rollers' arrangement of thrust cylindrical roller bearings makes it effectively disperses the axial load and reduces local stress concentration, finally achieving the target of extending the bearings' service life.
Thrust cylindrical roller bearings generally have excellent load-bearing capacity and durability. And they are suitable for heavy mechanical equipment that runs for a long time and carries huge axial pressure during operation. For example, machine tools, extruders, cranes and various transmission devices, etc.
The thrust tapered roller bearings' rollers are tapered and precisely arranged in the cage. The contact points between the rollers and the raceway are linear. They are significantly different from thrust cylindrical roller bearings.
Thrust tapered roller bearings can not only withstand large axial loads but also a few radial loads because of this tapered structure. They have many merits such as effectively dispersing loads and reducing friction during operation.
The advantages make thrust tapered roller bearings outstanding in certain low-speed and high-load situations, especially in machines where it is necessary to cope with complex loads. Thereby, they are commonly used in the automotive industry, construction machinery, heavy transmission equipment, and so on.
Thrust spherical roller bearings have the greatest feature--self-alignment capability. They are a special type of thrust bearings. Their rollers are spherical and have a certain self-alignment degree. So this type of bearings allows the shaft to have a certain degree of inclination and is able to compensate for displacement or deflection caused by installation errors or bearing seat deviations.
In addition, thrust spherical roller bearings have excellent load capacity because of their large contact area between the rollers and the raceways. At the same time, they can not only carry high axial loads but also withstand certain radial loads (the radial load must not exceed 55% of the axial load).
Some equipment usually operates in high-load, harsh working environments, such as hydroelectric generators, vertical engines, ship propeller shafts, cranes, extruders, etc. These machines commonly require the bearings to have self-adjustment capabilities to adapt to the alignment errors and dynamic loads in the equipment. Thrust spherical roller bearings are the best choice.
However, thrust spherical roller bearings are generally not suitable for high-speed rotation occasions.
