Features and advantages of QIBR three-row cylindrical roller slewing bearing DTR series
QIBR three-row cylindrical roller slewing bearing DTR series has many significant features and advantages, which are mainly reflected in the following aspects:
1.QIBR three-row cylindrical roller slewing bearing DTR series has high load-bearing capacity
QIBR three-row cylindrical roller slewing bearing DTR series design allows bearings to carry radial and axial loads in multiple directions at the same time, which is suitable for occasions with heavy loads and impact loads.
2.QIBR three-row cylindrical roller slewing bearing DTR series has good stability and long life
QIBR three-row cylindrical roller slewing bearing DTR series is loaded by three rows of rollers, and the working stability of the bearing is higher, which improves the reliability of the equipment and prolongs the working life.
3. QIBR three-row cylindrical roller slewing bearing DTR series customized service
QIBR three-row cylindrical roller slewing bearing DTR series can provide customized services, and can design bearings according to specific needs to meet the special requirements and working conditions of different industries.
QIBR three-row cylindrical roller slewing bearing DTR series
1. Improve bearing material performance
QIBR three-row cylindrical roller slewing bearing DTR series can use materials such as high-temperature resistant isolation blocks to improve the bearing's bearing capacity and service life.
2. Improve bearing rotation accuracy
QIBR three-row cylindrical roller slewing bearing DTR series is produced using advanced processing equipment and processes, such as machining centers and precision heat treatment, to improve the geometric accuracy of the inner and outer rings, reduce machining errors, and thus improve the bearing's rotation accuracy and stability.
3. Reduce the need for bearing maintenance and replacement
QIBR three-row cylindrical roller slewing bearing DTR series is designed with seals and lubricating oil holes. The seals can prevent contaminants from entering the bearing and reduce grease leakage; the lubrication holes are convenient for grease filling, which prolongs the service life and reduces the cost of maintenance and replacement.
4. Lubrication management
QIBR three-row cylindrical roller slewing bearing DTR series uses high-quality grease to improve temperature resistance and corrosion resistance, and ensure stability under different load and environmental conditions. Establish a lubrication plan. It is usually recommended to lubricate every 250 hours. Adjust the lubrication cycle appropriately according to the operating intensity.
5. Increase the number and size of rollers
QIBR three-row cylindrical roller slewing bearing DTR series can increase the number of rollers or increase the roller diameter to improve the load-bearing capacity when space permits.
In short, by optimizing materials, manufacturing accuracy, lubrication management and other measures, the performance of QIBR three-row cylindrical roller slewing bearing DTR series can be significantly improved to meet the increasingly demanding application requirements.
