The outer Spherical Ball Bearing is what we usually call the outer Spherical Bearing. The reason why it is called ball bearing is that it belongs to Deep Groove Ball Bearing, and the rolling element in it is steel ball.
Deep groove ball bearing outer spherical ball bearing is convenient to use the main characteristics of simple for loading and unloading, self-aligning ball bearings, standard tolerances for internal and external diameter reduction, adding tolerances to ensure the shaft with the light; each set of ball bearings are not alone to use and he must match to bearing inside the whole machine, the outer spherical bearing are of various shapes so the overall fit for various structural position after use. The ball bearing of the outer sphere can be divided into three categories according to the way of matching with the axis.

Li Changjiang said that the quality supervision mechanism mainly involves four aspects: First, the market access system has been implemented, and strict market access has been implemented for products involving safety, health, and environmental protection. This means the implementation of production license management and mandatory certification management. The second is the implementation of the national product quality supervision and inspection system. Each year, important and sensitive products are subject to state supervision and spot checks. The results of spot checks are announced to the public. The third is to implement a strict product inspection system to ensure the safety of product quality that enters circulation. Fourth, the product enters into circulation and implements a system for recall of defective products.
He said that recently the AQSIQ has intensified its efforts to build an electronic product quality supervision network. The completion of this network will start from the moment the product leaves the factory and enters the hands of consumers. This will enable product quality tracking throughout the entire process. It will be immediately found that counterfeit and shoddy products can be queried, complaints can be filed, and claims can be made. "Through the implementation of a series of systems, we should say that the quality of our products is safe and guaranteed."
Due to the establishment of a relatively complete product quality assurance mechanism, the overall level of China's product quality has been steadily improving in recent years. Information from the General Administration of Quality Supervision, Inspection and Quarantine shows that the improvement of product quality is reflected in four aspects.
The quality of raw materials and equipment products has greatly increased. The technical standards and physical quality of the main products of the non-ferrous metals and petrochemical industries have been brought into line with international standards. The equivalent available coefficient of the whole unit of power generation equipment has been increased to more than 85%. The localization rate of complete sets of equipment has greatly increased.
The quality and grade of consumer products have greatly increased. TVs have reached the advanced level in foreign countries, and 50% of the refrigerators exceed the European Union's level of energy efficiency.
The performance of high-tech products has improved significantly. The main functions and performance of products such as communication network equipment have reached the quality level of similar products in the world.
The quality of engineering and services has improved significantly. The qualified rate of general civil engineering reached 96%, and the qualified rate of national key projects reached 100%.
Outer spherical ball bearing with top wire
Its code is: UC200 series (light series), UC300 series (heavy duty Series), and deformation products UB (SB) 200 series. If the environmental load is small, UC200 series should be selected generally, otherwise UC300 series should be selected. Generally, there are two top threads on the outer spherical ball bearing, the angle between them is 120 degrees. The characteristic is that when the shaft fits with the shaft, the top wire is applied to the shaft to play a fixed role, but the environmental requirements for its matching must have a small vibration range. This kind of spherical ball bearing is widely used in textile machinery, ceramic machinery and other manufacturing industries.
Spherical spherical ball bearing with taper
Its name is: UK200 series, UK300 series. The inner diameter of the outer spherical ball bearing is the taper hole with a ratio of 1:12. When used, it must be combined with the tight sleeve. The characteristics of this kind of outer spherical bearing are: it can bear more load than the outer ball bearing with top wire. Because the diameter matched with the locking set the same model than with the top wire outer spherical ball bearing small, such as with the top wire outer spherical ball bearing UC209 inner diameter is 45mm, and is matched with the diameter of the shaft is 45mm, and if if change into a tapered outer spherical ball bearing, can only choose 45mm diameter sleeve, and 45mm adapter sleeve with taper outer spherical ball bearing is UK210 (of course, if the load is higher then you can choose the UK310). As a result, the load on UK210 is much larger than that of UC209.
Spherical spherical ball bearing with eccentric sleeve
Its name is: UEL200 series, UEL300 series, SA200 series. The main characteristic of this kind of spherical ball bearing is that there is a certain eccentricity on the upper end of the bearing, and the eccentric sleeve with the same eccentricity is cooperated with it. These bearings can also be said to be a special bearing, because it is mainly in agricultural machinery (harvester, straw machine, threshing machine etc.) on the use of this kind of outer spherical ball bearing is mainly used to beat hard structure, combined with the eccentric structure can effectively reduce the dynamic jump violently.
The outer spherical ball bearings than other ordinary bearings is a double seal, because the outer spherical ball bearing the use of environmental conditions are harsh, especially agricultural bearing even more, and the double sealing to ensure the dust is not easy to enter the channel within the last two years, some companies developed the outer spherical bearing three lip seal the more greatly enhance dustproof ability, prolonging the service life of the bearing.
The quality of China's equipment products has greatly improved
At the press conference held by the State Council Information Office on July 19, Li Changjiang, director of the General Administration of Quality Supervision, Inspection and Quarantine, said that the Chinese government attaches great importance to product quality. Over the years, the Central Government has established a relatively complete set of products that are in line with China's reality. Quality laws and regulations. At the same time, a working mechanism for strengthening product quality supervision has also been established. The quality of our products is safe and guaranteed.
