Features and advantages of QIBR sealed double row full complement cylindrical roller bearings

QIBR sealed double row full complement cylindrical roller bearings solves several key problems in various fields, which are mainly reflected in the following aspects:

1. QIBR sealed double row full complement cylindrical roller bearings high rigidity

QIBR sealed double row full complement cylindrical roller bearings 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 sealed double row full complement cylindrical roller bearings compact design

QIBR sealed double row full complement cylindrical roller bearings 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 sealed double row full complement cylindrical roller bearings has high load-bearing capacity

QIBR sealed double row full complement cylindrical roller bearings each roller almost contacts the load surface, so this bearing has a very high load-bearing capacity, especially suitable for applications with heavy loads.

4. QIBR sealed double row full complement cylindrical roller bearings save space

The characteristic of QIBR sealed double row full complement cylindrical roller bearings 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 sealed double row full complement cylindrical roller bearings energy saving

QIBR sealed double row full complement cylindrical roller bearings reduces 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 sealed double row full complement cylindrical roller bearings

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 sealed double row full complement cylindrical roller bearings 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 sealed double row full complement cylindrical roller bearings 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 sealed double row full complement cylindrical roller bearings adopt 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 sealed double row full complement cylindrical roller bearings use high-performance lubricants (such as synthetic oils, solid lubricants, nano lubricants, etc.) to improve lubrication effects and reduce friction and wear. In high temperature environments, the choice of lubricants is particularly important, and high temperature and corrosion-resistant lubricants or greases can be used.

Main application areas of QIBR sealed double row full complement cylindrical rollerbearings                   

1. Mining machinery 

Such as ball mills, crushers, vibrating screens and other equipment. These equipment will generate large radial loads during operation and have harsh working environments. QIBR sealed double row full complement cylindrical rollerbearings can effectively withstand such high loads and have high impact resistance.

2. Heavy machine tools: 

In high-precision heavy machine tools, QIBR sealed double row full complement cylindrical rollerbearings are used to withstand heavy loads and ensure the processing accuracy and stability of the machine.

3. Wind turbines: 

In important parts such as the main bearings of wind turbines, QIBR sealed double row full complement cylindrical rollerbearings 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.

4. Drilling equipment

In oil drilling equipment, QIBR sealed double row full complement cylindrical rollerbearings are used to withstand the high load and complex working environment of the drilling rig. It can maintain good operation under extreme conditions.
