Comparison Between Single-Row Cylindrical Roller Bearings and Spherical Roller Bearings  

Differences in Structural Design  

Single-row cylindrical roller bearings consist of cylindrical rollers, a cage, an inner ring, and an outer ring. The rollers make linear contact with the raceways, and their structure is relatively simple. Some models feature inner or outer rings without flanges and are classified as separable bearings—where the inner and outer rings can be disassembled. This design offers greater flexibility during installation and removal, eliminating the need for integral assembly or disassembly of equipment components.  

Spherical roller bearings, by contrast, adopt a design with two rows of symmetrically arranged barrel-shaped rollers. The outer ring is equipped with a single common spherical raceway, while the inner ring has two raceways inclined at a specific angle relative to the bearing’s axis. The cooperative structure of the spherical raceway and barrel-shaped rollers is key to realizing the bearing’s core functions, and it also represents the most significant structural difference from single-row cylindrical roller bearings.  

Distinctions in Load-Carrying Capacity  

There are clear differences between the two types of bearings in terms of load direction and load-bearing strength. Single-row cylindrical roller bearings primarily bear radial loads and exhibit high radial load-carrying capacity, with a rated dynamic load ratio typically ranging from 1.5 to 3. However, their axial load-carrying capacity is weak: flange-less models cannot withstand axial loads at all, and even flanged models can only bear small unidirectional axial loads, failing to meet the needs of multi-directional axial force applications.  

Spherical roller bearings, on the other hand, fall into the "radial + axial" composite load-bearing category. They can withstand both large radial loads and axial loads in any direction, with a rated dynamic load ratio of 2.3 to 5.2, making them more adaptable to heavy-load conditions—especially suitable for working environments with vibrational loads. It should be noted, however, that they cannot bear pure axial loads and must not be used in scenarios where only axial forces act.  

Comparison of Self-Aligning Performance  

Single-row cylindrical roller bearings have extremely high requirements for installation accuracy and basically no self-aligning capability. If there is misalignment between the shaft and the bearing housing, or if the shaft deflects during operation, it will directly cause uneven contact between the rollers and raceways inside the bearing, resulting in stress concentration. This accelerates bearing wear and significantly shortens its service life. Therefore, such bearings are only suitable for scenarios with strictly controlled installation accuracy and high shaft rigidity.  

Thanks to the structure of their spherical raceways and barrel-shaped rollers, spherical roller bearings possess excellent automatic self-aligning capability. They can automatically compensate for coaxiality deviations caused by shaft deflection, housing deformation, or installation errors, with a generally allowable self-aligning angle of 1° to 2.5°. This effectively avoids internal stress concentration, enabling stable operation even in working conditions with slightly lower installation accuracy or easily deformable shafts.  

Differences in Limiting Speed  

Single-row cylindrical roller bearings have low frictional resistance between the rollers and the ring flanges, generating less heat during operation. As a result, they have a high limiting speed and are suitable for high-speed rotation scenarios—such as machine tool spindles, high-speed motors, and precision gearboxes—where strict speed requirements exist. They can maintain stable performance even under high-speed operation.  

Due to their design with two rows of barrel-shaped rollers, spherical roller bearings have a larger contact area between the rollers and raceways, leading to relatively higher frictional resistance and more heat generation during operation. This results in a lower limiting speed, making them more suitable for medium- and low-speed rotating equipment and unable to meet the demands of high-speed working conditions.  

Distinctions in Application Scenarios  

Based on the aforementioned performance differences, the two types of bearings have distinct application focuses. Single-row cylindrical roller bearings are mainly used in scenarios such as machine tool spindles, high-speed motors, automobile gearboxes, and precision gearboxes—where both large radial loads and high requirements for speed and operating accuracy are present. Additionally, their separable structure makes them suitable for use as floating bearings to compensate for shaft displacement caused by thermal expansion and contraction.  

Spherical roller bearings, meanwhile, are widely applied in equipment that operates under heavy loads, vibrational loads, and potential installation misalignment—such as mining machinery (crushers, ball mills), iron and steel metallurgical equipment (rolling mills, continuous casters), papermaking machinery, and heavy-duty reducers. They can withstand heavy loads for long periods and maintain stability under complex working conditions, effectively addressing vibration and installation errors during equipment operation.
