Features and advantages of QIBR high-capacity cylindrical rollerbearings

QIBR high-capacity cylindrical roller bearings solves several key problems in various fields, which are mainly reflected in the following aspects:

1. High load capacity of QIBR high-capacity cylindrical roller bearings

QIBR high-capacity cylindrical roller bearings have more rollers than ordinary cylindrical roller bearings, and the contact area between the rollers and the inner and outer rings is larger, which enables the bearings to withstand higher radial loads.

2. QIBR high-capacity cylindrical roller bearings have good wear resistance

QIBR high-capacity cylindrical roller bearings have a lower wear rate due to the large contact area of ​​the rollers, which is suitable for equipment with high loads and long-term stable operation.

3. QIBR high-capacity cylindrical roller bearings have excellent rigidity and stability

QIBR high-capacity cylindrical roller bearings have small deformation when loaded and show high rigidity, which makes them particularly suitable for occasions such as machine tool spindles that require high precision and stability

4. QIBR high-capacity cylindrical roller bearings effectively control noise

The high-precision QIBR high-capacity cylindrical roller bearings can effectively reduce noise during operation and improve the overall performance of the equipment through precise installation, proper lubrication and advanced monitoring systems.

5. QIBR high-capacity cylindrical roller bearings are highly cost-effective

The design of QIBR high-capacity cylindrical roller bearings allows it to provide efficient load support in a relatively small space. Using QIBR high-capacity cylindrical roller bearings can reduce costs while improving rigidity and stability.

The performance improvement and solutions of QIBR high-capacity cylindrical roller bearings

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 bearing's operating performance and life.

2. Optimize rollers

By optimizing the roller shape, the contact stress can be reduced, the load capacity and durability can be improved. Roller surface treatment can reduce friction, improve rolling accuracy and load capacity, and extend the service life of the bearing.

3. Improve manufacturing accuracy

Adopting advanced foreign processing equipment and processes, such as precision grinding, super-finishing 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.

4. Improve material performance

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

Main application areas of QIBR high-capacity cylindrical roller bearings

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 high-capacity cylindrical roller bearings can effectively withstand this high load and have high impact resistance.

2. Heavy machine tools: In high-precision heavy machine tools, QIBR high-capacity cylindrical roller bearings are used to withstand heavy loads and ensure the processing accuracy and stability of the machine.

3. Drilling equipment: In oil drilling equipment, QIBR high-capacity cylindrical roller bearings are used to withstand the high load and complex working environment of the drilling rig. It can maintain good operation under extreme conditions.

4. Locomotive axle box: QIBR high-capacity cylindrical roller bearings are widely used in the axle box of railway locomotives. This bearing design can withstand high loads and effectively prevent the intrusion of dust and moisture, thereby improving the reliability and service life of the bearing.
