 Features and advantages of QIBR double-row standard spherical roller bearings

QIBR double-row standard spherical roller bearings solve multiple 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 the double-row spherical roller bearings 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 bear a certain axial load while bearing radial loads, and is particularly suitable for applications with low installation accuracy requirements.

2. Strong load-bearing capacity

The rollers of spherical roller bearings 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.

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 harsh working conditions. Spherical roller bearings have strong adaptability and can adapt to large axial offsets and radial load changes.

4. Easy installation

Compared with other types of roller bearings, double-row spherical roller bearings can simplify installation requirements and reduce the risk of bearing failure due to installation errors due to their self-aligning function.


The performance improvement and solutions of QIBR double-row standard spherical roller bearing

1. Lubricant optimization

Select appropriate lubricating oil or grease, and make appropriate additions and blends to reduce friction and improve wear resistance. Using 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. Using 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 standard spherical roller bearings

1.Mining machinery

Such as crushers, conveyors, ball mills and other equipment, due to their harsh working environment and heavy loads, double-row 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, double-row 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 bear a large amount of load and long-term operation, double-row spherical roller bearings have good self-alignment and are suitable for this type of equipment.

4.Shipbuilding industry

Double-row spherical roller bearings are often used in key parts of ships due to their excellent load-bearing capacity and durability in the rudder shaft, transmission shaft and other parts of ships.
