Features and advantages of QIBR double-row spherical roller bearings with adapter sleeves

QIBR double-row spherical roller bearings with adapter sleeves have solved many key problems in various fields, which are mainly reflected in the following aspects:

1. Self-aligning ability

The raceways of the inner and outer rings of double-row spherical roller bearings with adapter sleeves are curved, and the bearings have the function of self-aligning, that is, they can automatically compensate for the angular deviation caused by the bending of the shaft or the installation error. Therefore, it can withstand a certain axial load while bearing radial loads, and is particularly suitable for applications with low requirements for installation accuracy.

2. Strong load-bearing capacity

The rollers of double-row spherical roller bearings with adapter sleeves are cylindrical or slightly inclined, with a large contact surface, and can withstand large radial loads and bidirectional axial loads. Due to the large number of rollers, it has a higher load-bearing capacity, especially in high-load and high-impact application scenarios, and performs outstandingly.

3. Suitable for harsh working conditions

This type of bearing is often used in harsh environments such as high temperature, high speed, and heavy load, and can operate reliably under relatively harsh working conditions. Double-row spherical roller bearings with adapter sleeves have strong adaptability and can adapt to large axial offsets and radial load changes.

4. Easy to install

Compared with other types of roller bearings, double-row spherical roller bearings with adapter sleeves use adapter sleeves to prevent the bearings from loosening or slipping during operation. The adapter sleeve fixes the bearing to the shaft with bolts, usually with an internal hexagon or external hexagon design, which is easy to disassemble and install.


The performance improvement and solution of QIBR double-row spherical roller bearing with adapter sleeve

1. Lubricant optimization

Select appropriate lubricating oil or grease, and make appropriate additions and blends to reduce friction and improve wear resistance. The use of synthetic lubricants or nano-lubricants can significantly improve the efficiency and life of bearings.

2. Heat treatment process

Optimize the heat treatment process to ensure that the hardness and toughness of the bearing material are in the best state, and enhance its fatigue resistance and wear resistance.

3. Improve the quality of rolling elements

 Reduce friction and wear by improving the surface finish and hardness of the rolling elements. The use of high-precision rolling elements (such as ceramics) can significantly improve the operating performance of the bearing.

4. Cage design optimization

 Use a more optimized cage structure, such as using high-temperature and corrosion-resistant materials and designs to improve the durability of the cage and the stability of the bearing.


Main application areas of QIBR double-row spherical roller bearings with adapter sleeves

1.Mining machinery

Such as crushers, conveyors, ball mills and other equipment, due to their harsh working environment and heavy loads, spherical roller bearings can provide high load-bearing capacity and avoid failures caused by installation errors.

2.Metallurgical equipment

Such as rolling mill equipment and roller tables in steel plants, spherical roller bearings can effectively withstand heavy loads and impacts generated in metallurgical production.

3. Hydropower generator sets

Bearings of large power equipment such as turbines and generators. Since power equipment needs to withstand a large amount of load and long-term operation, spherical roller bearings have good self-alignment and are suitable for this type of equipment.

4. Agricultural machinery

Key components of agricultural machinery such as tractors and combine harvesters, especially those operating in rough environments. Due to the uneven ground or large vibrations in the working environment of agricultural machinery, spherical roller bearings can effectively reduce the loss caused by inaccurate equipment alignment.
