5. QIBR single row full complement cylindrical roller bearings without outer ring is highly cost-effective

The design of QIBR single row full complement cylindrical roller bearings without outer ring allows it to provide efficient load support in a relatively small space. Using QIBR single row full complement cylindrical roller bearings without outer ring can reduce costs while improving rigidity and stability.

The performance improvement and solutions of QIBR single row full complement cylindrical roller bearings without outer ring 

1. Dustproof and waterproof design

Especially in harsh environments, bearings need to have adequate protection measures to prevent dust, mud and water and other impurities from entering the bearings. This can be achieved by designing seals to avoid affecting the operating performance and life of the bearings.

2. Uniform load distribution

By optimizing the design and manufacturing process, ensure that the rollers in the bearings can evenly distribute the load during operation, avoid local overload, and thus improve the service life of the bearings.

3. Improve the bearing shape structure

By optimizing the geometry of the outer and inner rings (such as fillet design), reduce the friction between the inner and outer rings, and improve the smoothness and efficiency of operation.

4. Improve manufacturing accuracy

Use advanced foreign processing equipment and processes, such as precision grinding, super-fine grinding, etc., to improve the geometric accuracy of the inner and outer rings and rollers, reduce processing errors, and thus improve the rotation accuracy and roughness of the bearings.

5. Improve material performance

The use of surface coating technology (such as chrome plating, nitriding, etc.) can improve the wear resistance and corrosion resistance of bearings, effectively extend the service life of bearings, especially when working in harsh environments, the performance of bearings can be significantly improved.

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