Single row tapered roller bearings are primarily used to support rotational motion between shafts and bearing housings, reducing friction and providing support through rolling elements.

Double row tapered roller bearings are an important type of bearing characterized by a arrangement of tapered rollers between the inner and outer rings, capable of simultaneously bearing radial and axial loads in both directions.

Four row tapered roller bearings are a type of bearing with high precision and high load-carrying capacity, featuring four rows of tapered rollers arranged between the inner and outer rings.

Single row cylindrical roller bearings are a commonly used type of bearing, featuring a single row of cylindrical rollers arranged between the inner and outer rings.

Double row cylindrical roller bearings are renowned for their arrangement of double rows of cylindrical rollers, high load-carrying capacity, and excellent rigidity.

Four row cylindrical roller bearings feature four rows of cylindrical rollers arranged between the inner and outer rings. Typically comprised of two double row cylindrical roller bearings, these bearings support heavy loads and high-speed rotation by the relative movement of the inner and outer rings.

Single direction thrust ball bearings consist of spherical rollers and two bearing washers, with one bearing washer designed with grooves to accommodate the rollers, while the other bearing housing is flat.

Double direction thrust ball bearings are specialized bearings capable of withstanding thrust loads in both directions. They consist of spherical rollers and two bearing washers, with each bearing washer designed with grooves to accommodate the rollers.

Spherical roller bearings have two raceways on the inner ring and a spherical raceway, along with spherical rollers, on the outer ring. Because the center of the raceway on the outer ring aligns with the center of the entire bearing, these bearings are self-aligning.

Deep groove ball bearings are a very typical type of bearing due to their simple design, easy operation, and wide application. They are an inseparable type of bearing.
