Overview of Axial spherical roller bearing
Axial spherical roller bearings also have a shaft ring and a seat ring, the bearing seat on the shaft is pressed against the shaft ring, and the seal ring is installed when installing --- roller ---- shaft ring ----- the bearing seat of the shaft. Thrust spherical roller bearings are mainly used in petroleum drilling rigs, iron and steel machinery, hydroelectric generators, vertical motors, propeller shafts for ships, tower cranes, extruders, etc. The axial load capacity is large, while bearing the axial load, it can also bear a certain radial load. The spherical rollers of thrust spherical roller bearings are arranged obliquely, and the raceway surface of the raceway is spherical, which has self-aligning performance, so it can allow some tilting of the shaft. It can be used in extremely heavy loads, and the allowed speed is higher. Oil lubrication is generally used during use.
Thrust spherical roller bearings are separate bearings. The load action line forms a certain angle with the bearing axis, and the axial load capacity is large. While bearing the axial load, it can also bear a certain radial load. The spherical rollers of this type of bearings are arranged at an angle, and the raceway surface of the race is spherical, which has the self-aligning performance, so it can allow some tilting of the shaft. It can be used in extremely heavy loads, and the allowed speed is higher. Oil lubrication is generally used during use. Rolling bearings can be divided into radial bearings (mainly bearing radial loads), thrust bearings (only bearing axial loads), and radial thrust bearings (can be Understand both radial and axial loads). Radial thrust ball bearings, bearings of this structure, can withstand radial loads and axial loads in one direction. Find a contact angle of 15 degrees, 25 degrees, and 30 degrees with the inner and outer rings to obtain 40 degrees. The greater the contact angle, the greater the axial load-bearing capacity. The smaller the contact angle, the more conducive to high-speed rotation. Usually, the two bearings are opposed, and the internal clearance is adjusted before use.

Performance characteristics of thrust spherical roller bearings
High carrying capacity
A large number of rollers have the best consistency with the ring raceway, which helps the bearing to bear heavy axial and radial loads simultaneously.
Spherical roller thrust bearings are self-aligning and can withstand misalignment.
Thrust spherical roller bearings are separate types so that the seat ring can be installed and removed independently of the shaft washer and roller and cage assembly. In addition, this facilitates maintenance inspections. The cage design and the best consistency of the roller and washer raceways make the bearings suitable for relatively high speeds.
The special roller shape reduces the edge stress at the roller/raceway contact.
The optimized roller end/rib contact keeps the heat generated by friction at a low level even at high speeds.
How to install longer service life
Matching method: interference fit of the shaft and bearing box with shaft ring and seat ring
Installation method: Install the shaft ring by heating
Before installing the bearing, please read all the instructions carefully. The instruction manual contains a variety of optional tools and measurement methods. When selecting the tool recommended in the instructions for use, please check its availability based on the size of the bearings and other related components actually used.

1.Install the bearings in a clean environment. Check the bearing box, shaft and other related components of the bearing to ensure that they are clean.
2.Clean up the oil holes and oil grooves used in the oil injection method.
3.The installation and disassembly of rolling bearings sometimes involve the movement of heavy objects, the use of tools, other equipment, or the use of high-pressure oil. To avoid accidents, personal injury, or property damage, please follow the instructions carefully.
Before installing the bearing, check the dimensional and shape tolerances of all components in contact with the bearing. The diameter of the cylindrical journal is usually measured with a micrometer at four points on each of the three planes; the diameter of the inner hole of the cylindrical bearing box is usually measured using an internal gauge at four points on each of the three planes. Filling in measurement records and archiving will facilitate future tracking work. Measure the length of the mating surface of the bearing, shaft and bearing housing or the length of the matching sleeve. Based on the measurement results, calculate the axial clearance of the bearing configuration after installation. After the measurement is completed, install the bearing.
