Features and advantages of QIBR double-row different-diameter ball slewing bearing KUD_ZA series
QIBR double-row different-diameter ball slewing bearing KUD_ZA series has many significant features and advantages, playing a key role in various fields, mainly reflected in the following aspects:
1. QIBR double-row different-diameter ball slewing bearing KUD_ZA series has compact structure
The design of QIBR double-row different-diameter ball slewing bearing KUD_ZA series makes the bearing structure more compact, saves space, and is suitable for occasions with limited installation space.
2.QIBR double row different diameter ball slewing bearing KUD_ZA series has good stability and long life
The QIBR double-row different-diameter ball slewing bearing KUD_ZA series improves the stability of the bearing, reduces system vibration and noise, and improves the smoothness and reliability of operation. Optimized contact angle and load distribution reduce internal wear of the bearings, thereby extending bearing life.
3.The design of different diameter ball for QIBR double-row different-diameter ball slewing bearing KUD_ZA series
The two rows of balls of the QIBR double-row different-diameter ball slewing bearing KUD_ZA series bearings have different diameters. Usually, one row of balls is larger, while the other row is smaller. This design can make the bearing more even when transferring loads, which helps to reduce the uneven load caused by the different contact angles between the large and small balls, thereby increasing the service life and working stability of the bearing.
The use of different-diameter balls can improve the contact between the balls, making the load more evenly distributed inside the bearing, and also reducing the friction of the bearing.
The performance improvement and solutions of QIBR double-row different-diameter ball slewing bearing KUD_ZA series
1. Improve material performance of bearing
QIBR double-row different-diameter ball slewing bearing KUD_ZA series can adopts high-temperature sealing strips and other materials to improve capacity and service life of the bearing.
2.Improve rotation accuracy of bearing
The production of QIBR double-row different-diameter ball slewing bearing KUD_ZA series adopts advanced processing equipment and processes, such as machining center and precision heat treatment, to improve the geometric accuracy of inner and outer rings, reduce machining errors, and thus improve the rotation accuracy and stability of bearings.
3. Reduce the need for bearing maintenance and replacement
QIBR double-row different-diameter ball slewing bearing KUD_ZA series is designed with seals and lubricating oil holes. The seals can prevent contaminants from entering the bearing and reduce grease leakage; the lubricating holes are convenient for grease filling, the service life is extended, and the cost of maintenance and replacement is reduced.
4. Personalized design
For different occasions, QIBR double-row different-diameter ball slewing bearing KUD_ZA series can provide personalized size solutions to meet special applications. This not only enriches the standards of bearings, but also provides effective guidance for manufacturers to meet the personalized needs of users.
In summary, by optimizing materials, manufacturing accuracy, personalized design and other measures, the performance of QIBR double-row different-diameter ball slewing bearings KUD_ZA series can be significantly improved to meet increasingly demanding application requirements.
