Spherical roller bearings are a widely used type of spherical roller bearings; Spherical roller bearings are characterized by strong load-bearing capacity, good self-aligning performance, and the ability to automatically compensate for angle deviations caused by installation errors or shaft deflection. They are suitable for working conditions that bear heavy loads and impact loads. Spherical roller bearings are often used in mining and engineering machinery, metallurgical equipment, papermaking machinery, ships, wind power generation, reducers, rolling mills and other industries; Common types of spherical roller bearings include symmetrical spherical roller bearings, asymmetrical spherical roller bearings, cylindrical bore spherical roller bearings, tapered bore spherical roller bearings, etc.

Tapered roller bearings: The raceway surfaces of the inner and outer rings and the cone apex of the rollers are designed to converge at one point on the central axis of the bearing. The truncated cone rollers are assembled in the bearing as rolling elements and guided by the large flange of the inner ring. They can withstand radial loads and unidirectional axial loads. When the load acts on the bearing, an axial component is generated. Therefore, like angular contact ball bearings, two bearings are generally used opposite to each other, or they must be used in the form of double-row bearings. In this case, the appropriate internal clearance can be set by adjusting the spacing between the inner or outer rings. Because it is a separable type, the inner and outer rings can be removed separately. As a high-load capacity bearing, there is also an HR series with increased roller size and number of rollers. According to the size of the contact angle, it is divided into ordinary tapered angle, medium tapered angle, and large tapered angle bearings. According to the number of roller rows, it can be divided into double-row and four-row tapered roller bearings. Generally, a steel plate stamping cage is used, and a pin-type cage is also used for large-size tapered roller bearings.

Cylindrical roller bearings: The raceway surfaces of the inner and outer rings are cylindrical surfaces parallel to the central axis of the bearing. The rollers are cylindrical and in line contact with the raceway. The rollers are evenly separated and arranged by the cage. According to different structures, they can be divided into single-row, double-row and multi-row cylindrical roller bearings. Mainly bear radial loads, not suitable for bearing axial loads (axial loads need to be matched with thrust bearings). Due to the line contact characteristics between the rollers and the raceways, its radial load capacity is significantly higher than that of point-contact ball bearings, and the friction coefficient is small, which is suitable for high-speed rotation conditions. The inner and outer rings of the bearings can be separated (such as N-type, NU-type and other separable structures), which is convenient for installation and disassembly. Some types (such as NJ type, NF type) have single-side ribs, which can provide a certain axial positioning ability. According to the shape of the roller end, it is divided into ordinary cylindrical roller bearings and drum roller bearings (drum rollers can automatically compensate for micro-shaft deflection). The cages are mostly made of steel plate stamping or solid turning structures, and large-size bearings often use copper alloy cages to improve wear resistance.

Thrust spherical bearings AKMI's thrust spherical bearings are designed with spherical rollers and spherical raceways, which can adapt to the relative inclination of the shaft and the bearing seat while bearing axial loads. Its structure consists of a washer-shaped ring with a spherical raceway (shaft ring, seat ring) and a drum roller and cage assembly. The roller and raceway are in line contact, which significantly improves the load-bearing capacity and impact resistance. AKMI's thrust spherical bearings are mainly unidirectional (bearing unidirectional axial loads) and bidirectional (bearing bidirectional axial loads). The unidirectional type consists of two rings (shaft ring, seat ring) and a set of drum rollers and cages; the bidirectional type consists of three rings (two seat rings, one shaft ring) and two sets of roller assemblies, which can simultaneously bear bidirectional axial forces. Features - It has an automatic self-aligning function, allowing the shaft to tilt at a certain angle relative to the bearing seat (the self-aligning angle can reach 1.5°-3°) to compensate for installation errors or shaft deflection. - The line contact structure makes its axial load capacity significantly higher than that of thrust ball bearings, which is suitable for heavy load and impact load conditions. - The double-direction bearing can accurately control the clearance by adjusting the ring spacing to meet the preload requirements of different working conditions. - The spherical raceway design reduces edge stress and extends bearing life, which is suitable for low-speed, high-load scenarios (such as metallurgical equipment, mining machinery, heavy machine tools, etc.).
