1.What are the considerations for choosing between open, shielded, or sealed double row ball slewing bearing in specific applications?

While sealed bearings offer superior protection and maintenance advantages, shielded double row ball slewing bearing can be more suitable in situations where minimal friction and operating temperature are crucial. It's essential to assess the operational environment and demands before making a selection.
 

2.What maintenance practices are recommended to extend the lifespan of double row ball slewing bearing and prevent premature failure?

Proper handling and installation of double row ball slewing bearing is essential to preventing premature failure. Ensure that bearings are stored and transported in a clean, dry, and vibration-free environment. During installation, ensure that bearings are properly aligned, and torque is applied correctly.
 

3.Can double row ball slewing bearing operate in high-temperature environments like industrial ovens or furnaces, and how are they protected from heat-related damage?

double row ball slewing bearing are capable of working at temperatures up to +842°F (+450 °C). Special lubricants, seals and coatings make this possible by protecting the ball bearings from heat damage.
 

4.About double row ball slewing bearing,Can I add my own logo?

Yes, you can add your logo on bearings and packing box. We supply OEM SERVICE including bearing's size, logo, packing, etc.
 

5.What are the considerations for selecting sealed or shielded double row ball slewing bearing to protect against contamination and retain lubrication?

First, the environment in which your double row ball slewing bearing operate in can help you identify potential contaminants, allowing you to select your shields or seals accordingly. For example, shielded bearings have a gap that can allow finer contaminants or water from washdown applications to enter the bearing and get into the raceways.The challenge for sealing bearings is to seal the bearing by protecting the bearing from contaminants and running efficiencies.
 

6.How do preload adjustments in double row ball slewing bearing affect their performance and suitability for high-precision tasks?

Benefits of Preloading a Bearing
Optimizes the ball spin to roll ratio.
Increases the rigidity of an application.
Protects from excessive ball skidding.
Decreases application vibration and sliding friction.
High running accuracy (even if load conditions keep changing)
Increases bearing load capacity.
 

7.How do cage materials and designs impact double row ball slewing bearing performance and stability?

As the core component of rotating machinery, the performance and reliability of high-precision double row ball slewing bearing directly affect the overall performance and life of the machine and instrument . The increase of the rotational speed will aggravate the collision and friction of the cage, which will lead to the decrease of the rotational stability of the cage. The unstable movement of the cage could in turn lead to more severe collision and wear, thus reducing the life and reliability or even the destruction of the bearing.
Therefore, it is very necessary to study the cage stability to guarantee the stable operation of bearings. However, the dynamic characteristics of the cage is very complex. Parameters such as load, rotational speed and lubrication may affect its kinematic and tribological conditions, which leads to the change of its motion behavior.
 

8.What is the production capacity of the factory for double row ball slewing bearing?

The production capacity of Ningbo Haishu Nide International is:50000000pcs/month
 

9.Are there miniature double row ball slewing bearing designed for use in precision instruments and small-scale mechanisms?

Miniature bearings, despite their small size, play a significant role in various industries and applications. These compact powerhouses, typically measuring less than one inch in outer diameter, offer exceptional precision, durability, and reliability. Miniature bearings find extensive use in precision instruments and robotics.
 

10.Are there double row ball slewing bearing designed for use in critical medical equipment?

Precision double row ball slewing bearing are among critical components in medical devices that are vital to ensuring patient safety. Correct choice of suitable ball and ring materials and the right product design can ensure high-precision bearings — and medical devices — have a long service life.
Precision bearings are used in a wide variety of medical devices including surgical power tools, ventilators and heart pumps — and patient safety depends on them all. Whatever the device, there is an onus on medical device original equipment manufacturers (OEMs) to ensure that the right type of bearings are chosen, and fit precisely into the application.
 

11.How do manufacturers ensure the quality and reliability of double row ball slewing bearing through material selection and precision machining?

High-precision measuring instruments, such as micrometers and gauges, are used to check the dimensions of the rings and balls to ensure they meet tight tolerances. Surface Finish Inspection: Surface finish is assessed using profilometers to ensure the required smoothness and low friction characteristics.
 

12.How do preloaded double row ball slewing bearing enhance rigidity and reduce clearance in high-precision applications?

Enhance Rigidity: By applying a controlled axial force, preload increases the bearing's resistance to external forces and moments. This heightened rigidity is essential in applications where any deflection or misalignment must be minimized, such as in machine tools or robotic systems.
 

13.Can double row ball slewing bearing be used in vacuum or cleanroom environments, and what measures are taken to prevent outgassing or contamination?

Bearings specify stainless steel for vacuum or cleanroom applications as stainless steels used for the rings, balls and retainer exhibit low outgassing. They usually supply open or shielded stainless steel bearings as vacuum bearings as these will outgas less than a nitrile rubber sealed bearing.
