Features and advantages of QIBR double row full complement cylindrical roller bearings without outer ring

QIBR double row full complement cylindrical roller bearings without outer ring solves several key problems in various fields, which are mainly reflected in the following aspects:

1. QIBR double row full complement cylindrical roller bearings without outer ring High rigidity

QIBR double row full complement cylindrical roller bearings without outer ring Due to the dense contact between the roller and the inner ring, the rigidity of this bearing is relatively strong, which can provide stable support and precise operation.

2. QIBR double row full complement cylindrical roller bearings without outer ring Compact design

QIBR double row full complement cylindrical roller bearings without outer ring adopts a full-fill design, with a large number of rollers and a relatively small radial size, which can be used in places with limited space.

3. QIBR double row full complement cylindrical roller bearings without outer ring has high load-bearing capacity

QIBR double row full complement cylindrical roller bearings without outer ring Each roller almost contacts the load surface, so this bearing has a very high load-bearing capacity, which is particularly suitable for applications with heavy loads.

4. QIBR double row full complement cylindrical roller bearings without outer ring save space

The characteristic of QIBR double row full complement cylindrical roller bearings without outer ring is that it does not use an outer ring, but bears the load through the contact between the roller and the inner ring. This design makes the bearing more suitable for some applications with limited space.

5. QIBR double row full complement cylindrical roller bearings without outer ring save energy

QIBR double row full complement cylindrical roller bearings without outer ring reduce the friction between the outer ring and the inner ring: the design of direct contact between the roller and the inner ring reduces the friction between the outer ring and the inner ring, further reducing energy loss.

The performance improvement and solution of QIBR double row full complement cylindrical roller bearings without outer ring 

1. Improve corrosion resistance

For bearings that need to work in harsh environments, especially when used in humid, chemical media or salt spray environments, QIBR double row full complement cylindrical roller bearings without outer ring can use stainless steel or other corrosion-resistant materials, or perform special corrosion-resistant treatment on the bearing surface (such as electroplating, coating, etc.), thereby extending its service life.

2. Optimize rollers

QIBR double row full complement cylindrical roller bearings without outer ring can reduce contact stress, improve load capacity and durability by optimizing roller shape. Roller surface treatment can reduce friction, improve rolling accuracy and load capacity, and extend the service life of bearings.

3. Improve manufacturing accuracy

QIBR double row full complement cylindrical roller bearings without outer ring adopts advanced foreign processing equipment and processes, such as precision grinding, superfine grinding, etc., to improve the geometric accuracy of inner and outer rings and rollers, reduce processing errors, and thus improve the rotation accuracy and roughness of bearings.

4. Lubricant optimization

QIBR double row full complement cylindrical roller bearings without outer ring use high-performance lubricants (such as synthetic oil, solid lubricant, nano lubricant, etc.) to improve lubrication effect and reduce friction and wear. In high temperature environment, the choice of lubricant is particularly important, and high temperature and corrosion resistant lubricating oil or grease can be used.

Main application areas of QIBR double row full complement cylindrical roller bearings without outer ring

1. Mining machinery

Such as ball mills, crushers, vibrating screens and other equipment. These equipment will generate large radial loads during operation and have a harsh working environment. QIBR double row full complement cylindrical roller bearings without outer ring can effectively withstand such high loads and have high impact resistance.

2. Heavy machine tools

In high-precision heavy machine tools, QIBR double row full complement cylindrical roller bearings without outer ring are used to withstand heavy loads and ensure the processing accuracy and stability of the machine.

3. Precision gearbox 

QIBR double row full complement cylindrical roller bearings without outer ring are suitable for occasions requiring high load capacity, but due to its design structure, it is still suitable for machines with high precision requirements.

4. Wind turbines

In important parts such as the main bearings and gearbox bearings of wind turbines, QIBR double row full complement cylindrical roller bearings without outer ring provide excellent load support capabilities. Especially in strong wind and high load working environments, it can ensure the long-term operation of wind power equipment.
