Affected by the global financial crisis, China's economic growth rate in the first quarter showed signs of slowing down. Tian Lipu believes that under such circumstances, some regions and enterprises are still developing rapidly, showing strong anti-risk ability and strong development momentum. One of the important reasons is that these regions have a relatively good intellectual property environment and foster A group of competitive companies with their own brands and core technologies. These companies are able to offer high value-added products. Strengthening independent innovation and strengthening the capacity building of independent intellectual property rights are important measures to deal with the financial crisis. After the financial crisis came, exports were blocked, but the production and exports of these enterprises did not fall, which gave us important inspiration.
In 2008, China's intellectual property application and authorization grew rapidly. In the whole year, a total of 828,000 patent applications were accepted, a year-on-year increase of 19.4%; a total of 412,000 patents were granted during the year, an increase of 17.1% year-on-year; as of March 16 this year, China's accumulated patent applications exceeded 5 million.
In terms of trademarks, in 2008, a total of 698,000 trademark registration applications were accepted; in the review of trademark registration applications of 750,000, the annual review of trademark registration applications exceeded the number of applications for the first time; a total of 403,000 registered trademarks were approved, and by the end of 2008, China’s registration The total number of trademarks reached 3.441 million.
In terms of copyright, the total number of software registrations last year was 49,000, the number of copyright contract registrations was 12,000, and the number of voluntary registrations was 1.04 million. In addition, the application and authorization of new plant variety rights has also increased significantly.
At the same time, new breakthroughs have been made in the enforcement of intellectual property rights and the environment has been improved. The leading role of judicial protection of intellectual property rights in China has been further enhanced, and the interests of rights holders and the public have been effectively safeguarded. International cooperation and exchanges on intellectual property protection have been deepened, and bilateral and multilateral cooperation have opened up new horizons.
Tian Lipu introduced that China's intellectual property system is improving day by day. As a responsible developing country, China will continue to improve the intellectual property legal system and strengthen intellectual property protection in accordance with China's national conditions while complying with WTO rules and international intellectual property rules.
Spherical Roller Bearings are most suitable option for applications that need shock resistant components yet this is not the only quality these Bearings have. These Bearings can handle heavy loads because of their rings` alignment. Due to the curved outer ring, Spherical Bearings come with self aligning capabilities that make it possible to absorb shocks and also enable the apparatus to carry high axial and radial load even in harsh environment with lot of vibration. Even with this rugged working environment, Roller Bearings tend to have high precision.
DESIGN
Spherical Bearings have two rows of rollers that are separated by a cage or rib that could be sealed or unsealed depending on the specific model and application, external raceway and dual raceways in inner ring to support rotating shaft. Amazingly the quality and alignment of raceways, cages and rings define the overall performance and quality of the product. Asymmetrical rollers increase performance and precision while symmetrical rollers offer better load distribution, lesser vibration that ultimately leads to durability.
MATERIAL
These Bearings are manufactured with several kind of material based on the application and working environment. Chrome steel is one of the most popular materials used in production of these Bearings because of its durability yet sheet steel, polyamide and brass are also used for some applications. One of the most important parts of Spherical Bearings is the cage that holds bearings at their place. That cage is usually manufactured with pressed steel or brass because both of these materials offer strength as well as temperature resistance.
These Bearings tend to have seals in order to prevent contaminants like dirt, liquid, debris as well as harsh temperature. This type of these bearing doesn`t even need lubrication if they do not exceed 50% of their maximum allowed RPM.
APPLICATIONS
Spherical Bearings are essential part of heavy machines like gearboxes, turbines, mechanical fans, constructions equipment, mining equipment and drilling equipment. Roller Bearings are available in multiple standard sizes and dimension yet they are also made with custom sizes and specifications.

MODELS AND VARIATIONS
Usually these Bearings come in two different types that have totally different design, structure, specifications and applications.
Single Row Spherical Roller Bearings
These are also known as Barrel Bearings because of their design and they are widely used where only low radial load carrying capacity is required. Other than the load capacity difference, Single Row these Bearings is quite similar to their counterpart in terms of performance and durability.
Double Row Spherical Roller Bearings
These are used where high radial load carrying capacity if required and that make them an essential part of almost all heavy duty machinery out there. The design difference between these two is obvious; Double Row Roller Bearings come with central flanges that optimize the overall performance of the apparatus.
