Features and advantages of QIBR four-row cylindrical roller bearing FCD series
QIBR four-row cylindrical roller bearing FCD series solves multiple key problems in various fields, which are mainly reflected in the following aspects:
1. QIBR four-row cylindrical roller bearing FCD series has high rigidity
QIBR four-row cylindrical roller bearing FCD series has relatively strong rigidity due to the dense contact between the roller and the inner ring, which can provide stable support and precise operation.
2. QIBR four-row cylindrical roller bearing FCD series has compact design
QIBR four-row cylindrical roller bearing FCD series adopts full-fill design, with a large number of rollers and relatively small radial dimensions, which can be used in places with limited space.
3. QIBR four-row cylindrical roller bearing FCD series has high load-bearing capacity
QIBR four-row cylindrical roller bearing FCD series has almost every roller in contact with the load surface, so the load-bearing capacity of this bearing is very high, especially suitable for applications with heavy loads.
4. Energy saving of QIBR four-row cylindrical roller bearing FCD series
QIBR four-row cylindrical roller bearing FCD series 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 four-row cylindrical roller bearing FCD series
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 four-row cylindrical roller bearing FCD series can use stainless steel or other corrosion-resistant materials, or perform special anti-corrosion treatment on the bearing surface (such as electroplating, coating, etc.) to extend its service life.
2. Optimize rollers
QIBR four-row cylindrical roller bearing FCD series can reduce contact stress, improve load capacity and durability by optimizing the 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 four-row cylindrical roller bearing FCD series adopts advanced foreign processing equipment and processes, such as precision grinding, super-finishing, 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 four-row cylindrical roller bearing FCD series uses high-performance lubricants (such as synthetic oil, solid lubricant, nano lubricant, etc.), which can improve lubrication effect and reduce friction and wear. In high temperature environment, the choice of lubricant is particularly important. High temperature and corrosion-resistant lubricating oil or grease can be used.
Main application areas of QIBR four-row cylindrical roller bearing FCD series
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 four-row cylindrical roller bearing FCD series can effectively withstand such high loads and has high impact resistance.
2. Heavy-duty machine tools
In high-precision heavy-duty machine tools, QIBR four-row cylindrical roller bearings FCD series are used to bear heavy loads and ensure the processing accuracy and stability of the machine.
3. Precision gearboxes
QIBR four-row cylindrical roller bearings FCD series are suitable for occasions that require high load capacity, but due to its design structure, they are 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 four-row cylindrical roller bearings FCD series 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.
