Ningbo Haishunide International Co., Ltd. is specialized in bearings export production selling and after-service. In practice for many years, we established strict quality assurance system. Our products range covers Cylindrical Roller Bearing, Needle Roller Bearing, Tapered Roller Bearing, Spherical roller bearing, Deep Groove Ball Bearing, Angular Contact Ball Bearing,etc.We can do OEM products, and do following drawings.
Ball bearing swivels sizes vary according to their use. The width of the bearing also depends on the application. For example, thin section bearings are used in situations where space is at a premium. The difference between the diameter of the outside and inside races and width is minimized, allowing for compact designs. The materials used in ball bearings depend on their application. The vast majority of ball bearings are made from steel. Other material types include stainless steel bearings for improved corrosion resistance and hybrid ball bearings for which ceramic balls are the moving parts of the bearing between the inner and outer races to reach high rotational speeds.
ball bearing swivels, which play an important role in the engineering field, are an important type of rolling bearing characterized by long service life, strong load capacity, and good sealing performance. In addition to traditional single row ball bearings, there are also various types of double row, four row, and cross roller ball bearings that can meet various engineering needs. At present, with the development of technology, ball bearings are constantly innovating and improving to adapt to more and more complex mechanical equipment applications.
As a high-precision rotating equipment, ball bearing swivels play an important role in various mechanical manufacturing fields, consisting of precision manufactured components such as inner spherical surfaces, outer spherical surfaces, cages, steel balls, etc. It achieves support and load transfer between the shaft and the shaft seat by rolling the steel ball between the inner and outer spherical surfaces. Ball bearings have advantages such as strong load capacity, high speed, and long service life, and are widely used in important fields such as aerospace, ships, and trains.

ball bearing swivels--A Guide to Frequently Asked Questions
1.What is a ball bearing？
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
2.Can ball bearings 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.
3.How do preloaded ball bearings 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.
4.How do cage materials and designs impact ball bearing performance and stability?
As the core component of rotating machinery, the performance and reliability of high-precision 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.
5.Are there ball bearings designed for use in critical medical equipment?
Precision bearings 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.
6.What is the role of ball bearing swivels in reducing friction and wear in automotive applications, such as wheel hubs and transmissions?
When a load is applied to a ball bearing, the ball bearing swivels roll freely between the inner and outer rings. This rolling action significantly reduces friction compared to sliding contact, resulting in smoother rotation and reduced wear.
7.Can ball bearings operate in high-temperature environments like industrial ovens or furnaces, and how are they protected from heat-related damage?
Ball bearings 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.
8.Where can ball bearing swivels be used?
ball bearing swivels are very versatile. They can be designed to withstand radial loads, axial loads and combined radial/axial loads at various operating speeds. These characteristics, combined with the relative cost and compactness of the design, give it universal appeal within the industry. Ball bearings are widely used in electric motors, gear reducers and pumps. Serving the automotive, home appliances, aerospace, oil and gas drilling, and mining sectors.
9.Can ball bearing swivels operate in high-speed applications, and what design features make them suitable for such conditions?
They have very low rolling friction and are optimized for low noise and low vibration. This makes them ideal for high-speed applications. ball bearing swivels are comparatively easy to install and require minimal maintenance.
10.What are the advancements and innovations in ball bearing swivels technology that have emerged in recent years?
Significant advancements have been made in bearing steels over the years. Modern, ultra-clean bearing steels contain fewer and smaller non-metallic particles, giving ball bearings greater resistance to contact fatigue.
11.Are there hybrid ball bearings that combine steel rings with ceramic balls to optimize performance in demanding applications?
Hybrid Ceramic Ball Bearings. Ceramic ball bearings (also known as hybrid bearings) are the one component that'll easily optimize the performance of your application. Hybrid bearings have ceramic (silicon nitride, Si3N4) balls and 52100 bearing steel rings.
