The Cage Makes Single Row Cylindrical Roller Bearings More Stable

The components of a single row cylindrical roller bearing are relatively simple: solid inner ring, solid outer ring, cylindrical rollers and cage. These components work together to achieve the stable performance of the single row cylindrical roller bearing.

Among them, the cage plays a very important role. The function of the cage is to evenly separate each cylindrical roller, ensuring uniform force on the bearing while also avoiding mutual friction between the rollers. However, the cage itself cannot bear the load, but a cage made of high-performance materials can effectively reduce its own weight, reduce friction, and improve the operating efficiency and service life of the bearing.

Errors and Limitations of the Bearing Angle

Single row cylindrical roller bearings perform exceptionally well in radial load capacity, but their axial load capacity is quite limited. If they must bear a certain axial load, it is necessary to ensure that there is sufficient lubrication in the contact area between the roller end face and the flange to avoid direct contact and wear between metals. However, this axial load capacity is very limited. At the same time, single row cylindrical roller bearings can only tolerate limited angular errors and misalignments.

These limitations are not weaknesses of single row cylindrical roller bearings, but rather they more clearly define its application scope. Choosing the correct bearing and usage method will make your investment twice the result with half the effort.

From Heavy Industry to the Application of Precision Machine Tools

Single row cylindrical roller bearings, relying on their unique performance advantages, have been widely applied in various mechanical equipment. As the basic type of cylindrical roller bearings, the single row design is suitable for most standard applications:

FREQUENTLY ASKED QUESTIONS

What are the advantages of single-row cylindrical roller bearings compared to double-row cylindrical roller bearings?

Simpler structure: Single-row structure has fewer parts, making installation and disassembly easier and reducing costs.
Better high-speed performance: The single-row structure has less frictional resistance and generates less heat, making it suitable for high-speed applications.
More suitable for compact spaces: The single-row structure has a smaller width, making it suitable for scenarios with limited axial space.

What materials are general single-row cylindrical roller bearings made of?

Single row cylindrical roller bearings are generally made of chrome steel, which has a high hardness and good high-speed performance, making it suitable for high-speed or heavy-duty applications.

What installation methods are generally used for single row cylindrical roller bearings?

The installation method for bearings can be selected based on their size and the tightness of the fit, either cold installation or hot installation:

Cold installation: This is suitable for small bearings with a not too tight fit. A sleeve and hammer can be used to gently tap the sleeve to install the bearing in the correct position. During tapping, ensure that the force is evenly distributed on the bearing ring to prevent it from tilting or skewing.
Hot installation: For larger bearings that require more force to install, hot installation is typically used. By heating the bearing to expand it, it can be more easily installed onto the shaft journal or bearing housing.

For bearings with tapered bores, the inner ring is usually installed with an interference fit on the tapered shaft journal. During installation, the degree of interference fit must be precisely determined by measuring the reduction in radial clearance or the advancement distance of the inner ring on the tapered mating surface.
