eep groove ball bearings or single row radial ball bearings, are the most common type of rolling bearings. Their use is very widespread. It usually consist of a pair of rings, a retainer, a single row of steel balls. The two races are grooved or shaped on their inner surfaces to accept and retain the balls, Single Row Deep Groove Ball Bearings have the highest speed capacity of all rolling element bearings, Deep Groove Ball Bearing is mainly used to bear radial load and operating at relatively high speeds, but it can also bear a certain amount of axial load in either direction.
Feature:
Compared with other bearings, deep groove Ball Bearing has smaller friction coefficient and higher limiting rotate speed, it is more durable and universal with low noise and is easier to install. Deep groove 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.
Since sliding cannot be eliminated in the contacts between the cage and other bearing parts, the cage itself is the first component to be affected when lubrication becomes inadequate. Our ball bearings use unique design polyamide and steel cage, The inner/outer rings and Retainer(cage) are thicker compare with the Common bearings, stronger rivet, which consist more reliable structure. strong impact and heavy load with Grinding groove and super finishing technology. to offer the long life under extreme harsh environment.
Clearance:
Deep groove ball bearings have internal clearance. This provides the bearing room for expansion between the bearing races and will add a small amount of play between the two rings. Large clearance C3/C4 usually used in harsh environment. with good anti-seize performance used in particularly harsh environment.
Tolerances
The standard version of our single-row deep groove ball bearings has the tolerance class P0
(designs with tighter tolerances available upon request)
Types:
1. Classified according to sealed type:
Open type: Open type deep groove bearings are manufactured without seals to allow for the free circulation of either oil or grease, cost effective solution
Shielded type: With one shield (-Z) on one side or two shields (-2Z/ZZ) on both sides; Shielded bearings are provided with non-contacting metal shields that protect against larger particles entering the bearing, but do not protect against liquids. They add no friction during operation and therefore do not generate heat build-up.
Sealed type: With one seal (-RS) on one side or two seals (-2RS) on both sides. Sealed bearings are supplied with a contacting lip seal that excels in protecting the bearing from liquids and other foreign contaminants. The inherent design creates friction, drag, and in turn heat; factors that require consideration in high speed applications.
2. Classified according to the Retainer/Cage:
Nylon cage deep groove ball bearing: Our KA(Nylon retainer) series bearings Obtained MA certification of China Coal Research Institute, safety certificate of approval for mining products (rollers) in China, with good performance of anti-seize and anti-static.
Steel cage deep groove ball bearing: Thicker cage with stronger rivet, which consist more reliable structure.

Since 2013, China's industrial robot technology has developed rapidly, mainly due to the four aspects of national policy protection, macroeconomic promotion, social environment promotion, and technology development support.
As labor costs increase, people are forced to use robots instead of humans for production. At the same time, as some of China's key core components have gradually become localized, localization of core components has been realized for low-end robots, and the emergence of new technologies will promote the further development of robotics technology.
In the application industry, the largest application industry is in the automotive manufacturing sector, which accounts for 38.7%, while the domestic data is even larger, and nearly 50% is used in the automotive manufacturing sector.
It is understood that the production of the four major automotive processes and the production of key automotive parts and components require the participation of industrial robots. In the production of automobile body, there are a large number of applications such as die casting, welding, testing, etc. These are currently completed by industrial robots. In particular, welding lines, a welding line has a large number of industrial robots, and the degree of automation is quite high.
On the other hand, in the production of automobile interior parts, skin weakening robots, foaming robots, and finally product cutting robots are required. Because of the heavy workload and strong nature of painting, auto bodywork is usually replaced by industrial robots. Therefore, to complete the manufacture of a car, a large number of robots are required, and industrial robots have become key intelligent devices in automobile production.
The increase in the application of industrial robots in the power/electronics industry over the past few years has also been rapid. It has now reached about 21%, and this ratio is expected to increase further. Especially in China, the production capacity of electronic products accounts for about 60%-70% of the world's total. Therefore, in China's power/electronics industry, the application of industrial robots will have a larger market.
Industrial robot technology is a representative of advanced manufacturing technologies and is a concentrated expression of national industrial competitiveness. At present, China has become the largest market for industrial robots. Although the market demand is very strong, but it also brought some signs of overheating in the industry. In general, the key technologies for industrial robots in our country are still relatively backward in the world, and many key components still need to be imported.
Judging from China’s current robotic industry, there are as many as 20 provinces with a focus on the development of the robotics industry in China, and more than 40 robotic industrial parks. In the past two years, the number of robot manufacturers has rapidly increased from less than 300 to more than 800, and the related industrial chain has more than 4,000 companies. At present, China's robotics industry has a certain degree of overheating and low-level redundant construction. Blindly launching phenomenon exists in many areas.
In addition, experts pointed out that how to change from quantity and speed to quality and connotation is the biggest problem in the development of the local robotics industry. At the same time, local support policies have also promoted the development of the industry, but also induced repeated construction, vicious competition and other issues, resulting in uneven quality of the company's products, weakening the confidence of users using autonomous robots. Therefore, China's industrial robot industry wants to become bigger and stronger, but also to solve many problems.
China's robotic application market is growing rapidly. Industry analysts predict that sales of robots in China will reach 102,000 in 2017. However, at the same time, the competition and overheated investment of low-end terminal manufacturers will hinder the improvement of industrial competitiveness.
