ZYS Tapered roller bearings

Main structural forms

1.Single row tapered roller bearing

Single row tapered roller bearing can limit the axial displacement of the shaft or shell in 1 direction and bear the axial load in 1 direction. Additional axial force is generated under the action of radial load. Therefore, in the 2 supports of the shaft, the end faces of bearing outer ring and bearing inner ring are oppositely mounted. If used alone, the applied axial force must be greater than the additional axial force. The 313 series tapered roller bearings have large contact angles (27°~ 30°) and can withstand large axial loads. The contact angle of tapered roller bearings in other series is between 10°and 18°.

2. Double row tapered roller bearing

Double row tapered roller bearing has a pair of raceway outer ring and 2 inner rings, and a middle spacer between the 2 inner rings. The thickness of the spacer can be adjusted to adjust the bearing clearance. Double row tapered roller bearing can bear the bidirectional axial load while bearing the radial load. It can limit the bidirectional axial displacement of the shaft or shell within the axial clearance range of the bearing.

3. Four row tapered roller bearings

Four row tapered roller bearings adopt 2 double raceway inner rings, 1 double raceway outer ring and 2 single raceway outer rings, and there are spacers between inner ring and outer ring for adjusting clearance. It has similar performance with double row bearing: large radial load and low limit speed. Four row tapered roller bearings are mainly used for heavy machinery, such as rolling mill.

cylindrical roller bearing

What are the potential challenges or limitations of using cylindrical roller bearings in specific industries?

While cylindrical roller bearings offer numerous advantages, there are also certain challenges and limitations associated with their use in specific industries. Let’s explore some of these potential challenges:

  • High-Speed Applications:

In industries that require high-speed rotating machinery, such as machine tools or centrifugal compressors, the limitations of cylindrical roller bearings become more pronounced. At high speeds, factors like centrifugal forces, increased operating temperatures, and the potential for roller skidding can impact the bearing’s performance. Special design considerations, such as optimized cage designs, precision manufacturing, and proper lubrication, are necessary to overcome these challenges and ensure reliable operation at high speeds.

  • High-Temperature Environments:

In industries like steel production, glass manufacturing, or certain types of furnaces, the operating temperatures can exceed the limits of standard cylindrical roller bearings. High temperatures can cause dimensional changes, affect the lubricant properties, and lead to accelerated wear or premature failure of the bearing components. To address this limitation, specialized high-temperature bearings with heat-resistant materials, advanced lubrication systems, and appropriate sealing mechanisms are required.

  • Heavy Load and Shock Loads:

Industries involving heavy machinery, such as construction, mining, or material handling, often subject cylindrical roller bearings to extremely heavy loads or sudden shock loads. These conditions can lead to increased stress, fatigue, or even permanent deformation of the bearing components. To overcome these challenges, bearings with higher load-carrying capacities, robust designs, and enhanced fatigue resistance are necessary. Additionally, proper maintenance practices and regular monitoring are crucial to detect any signs of excessive load or potential failure.

  • Contamination and Harsh Environments:

In industries characterized by harsh operating environments, such as agriculture, forestry, or automotive manufacturing, cylindrical roller bearings can face challenges related to contamination, moisture, or exposure to abrasive particles. Contaminants can accelerate wear, cause damage to the bearing surfaces, or impair the lubrication effectiveness. Sealing solutions, effective maintenance practices, and the selection of appropriate bearing materials are essential to mitigate these challenges and ensure reliable performance in such environments.

  • Space Limitations:

In certain industries like aerospace or robotics, where space is limited and compact designs are required, the size and dimensions of cylindrical roller bearings can pose challenges. Finding suitable bearing sizes that meet the specific space constraints while still fulfilling the load and performance requirements can be a limitation. In such cases, alternative bearing types or customized bearing solutions may be explored to overcome the space limitations.

It’s important to note that while there may be challenges or limitations associated with using cylindrical roller bearings in specific industries, advancements in bearing technology, materials, and design continue to address and overcome many of these limitations. Consulting with bearing manufacturers, considering application-specific requirements, and implementing appropriate maintenance practices can help mitigate these challenges and ensure the successful use of cylindrical roller bearings in a wide range of industries.

cylindrical roller bearing

Can you explain the design and structure of cylindrical roller bearings?

Cylindrical roller bearings have a specific design and structure that enables them to handle high radial loads and moderate thrust loads. Let’s explore the key components and features of cylindrical roller bearings:

  • Inner and Outer Rings:

The inner and outer rings of cylindrical roller bearings are typically made of high-quality bearing steel. The inner ring is mounted on the rotating shaft, while the outer ring is usually mounted in a stationary housing. The rings are precision-machined with raceways that serve as the contact surfaces for the cylindrical rollers.

  • Cylindrical Rollers:

Cylindrical rollers are the main load-carrying components of the bearing. They are cylindrical in shape and have a high length-to-diameter ratio. The rollers are precision-ground to ensure close tolerances and uniform size distribution. The large contact area between the rollers and the raceways allows for efficient load distribution and reduced stresses.

  • Cage:

A cage, also known as a separator, is used to keep the cylindrical rollers evenly spaced and prevent them from coming into contact with each other. The cage is typically made of steel or other materials such as brass or polyamide (nylon). It provides guidance and retains the rollers in position during operation, ensuring smooth rolling motion and preventing roller skewing or jamming.

  • Flanges:

Cylindrical roller bearings may have flanges on the inner or outer rings or both. Flanges are raised edges or shoulders that provide axial guidance and help in locating the bearing in the axial direction. The presence of flanges can also improve the overall rigidity and axial load-carrying capacity of the bearing.

  • Internal Clearance:

The internal clearance of cylindrical roller bearings refers to the space between the rollers and raceways when there is no external load applied. It affects the bearing’s thermal expansion, running accuracy, and ability to accommodate misalignment or axial displacement. Different levels of internal clearance are available to suit specific application requirements.

  • Lubrication:

Cylindrical roller bearings require proper lubrication to minimize friction, reduce wear, and dissipate heat generated during operation. Lubrication helps to maintain the separation between the rolling elements and raceways, preventing metal-to-metal contact and minimizing the risk of premature failure. Common lubrication methods include grease lubrication and oil lubrication.

  • Sealing and Protection:

Cylindrical roller bearings can be equipped with various types of seals or shields to prevent the ingress of contaminants and retain lubrication. These seals and shields help to extend the bearing’s service life and maintain its performance by providing protection against moisture, dust, and other external factors that could cause damage or deterioration.

Overall, the design and structure of cylindrical roller bearings allow them to efficiently handle radial loads and moderate thrust loads. The combination of inner and outer rings, cylindrical rollers, cage, flanges, internal clearance, lubrication, and sealing work together to provide reliable and smooth rotational motion in machinery applications.
