QIBR thrust spherical roller bearings solve several key problems in various fields, which are mainly reflected in the following aspects:

1. High load capacity

Thrust spherical roller bearings can withstand large axial loads. Due to the large contact area of the rollers, the bearings can share a larger axial force, especially suitable for high-load working environments.

2. High rigidity

Due to its structural characteristics and the design of cylindrical rollers, thrust spherical roller bearings have high rigidity. It can effectively reduce axial deformation, provide more stable movement and higher load capacity, suitable for high-precision and high-load applications.

3. Self-aligning roller structure

The bearing uses specially designed rollers inside, which can maintain a proper contact angle during operation, thereby improving the service life and performance of the bearing. Usually, these rollers are spherical rollers, and their contact surfaces form a self-aligning effect between the inner and outer rings of the bearing.

Wide range of applications: This bearing is widely used in mechanical equipment that needs to withstand axial loads and has shaft offset or misalignment.


QIBR thrust spherical roller bearing performance improvement and solutions

1. Improve material selection

High-performance materials: Use high-strength, high-wear-resistant materials to improve the durability of bearings.

High-temperature resistant materials: When working in a high-temperature environment, choosing high-temperature resistant materials can maintain the performance of the bearing and prevent material deformation or failure due to excessive temperature.

2. Optimize roller design

Optimize roller shape: By optimizing the geometry and size of the rollers, the bearing's load capacity and working performance can be improved.

Improve the uniformity of roller spacing: Improve the design of the cage to ensure that the rollers maintain a uniform spacing during operation, thereby improving the uniformity of the load distribution of the bearing and reducing local overload and wear.

Increase the number of rollers: Increasing the number of rollers inside the bearing can further improve the bearing's load capacity, especially for high-load bearing occasions.

3. Improve manufacturing accuracy

Higher bearing manufacturing accuracy: Improve the operating accuracy and stability of the bearing by improving processing accuracy, controlling tolerances and optimizing production processes.

4. Optimize lubrication management

Choose the right lubricant: Choose the right lubricant or grease according to the temperature, load and speed of the working environment to ensure that the bearing maintains proper lubrication during operation and reduces friction and wear.

Regular lubrication and maintenance: Check the lubrication status regularly, replace the lubricant or grease in time, avoid lubricant deterioration or contamination, and ensure long-term stable operation of the bearing.


Main application areas of QIBR thrust spherical roller bearings

1. Mining and metallurgical industries

Mining equipment: Various heavy machinery used in the mining process, such as crushers, screening machines, etc., usually require thrust spherical roller bearings to withstand the huge axial loads and impact loads generated during the operation of the equipment.

Metallurgical equipment: High-load parts of equipment such as steel smelting are often equipped with thrust spherical roller bearings to ensure the stable operation of the equipment.

2. Ship industry

Ship propulsion system: Thrust spherical roller bearings are used in ship propellers, steering gears and other parts. They can withstand the axial forces generated by the propulsion system and steering gear, and maintain stable operation.

Ship steering gear: Since the steering gear needs to withstand a large axial load, the thrust spherical roller bearing can ensure its normal operation and provide the necessary aligning function.

3. Hydroelectric generator sets

Thrust spherical roller bearings are widely used in the rotor components of hydroelectric generator sets to withstand the axial loads generated by the generator sets during operation.

4. Metallurgy, mining, oil field and other equipment

Thrust spherical roller bearings are often used in oil field drilling rigs, smelting equipment and other machinery to withstand heavy loads and stresses.
