Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.

Backing bearings is now recognized worldwide as the finest bearings
Bearings is now recognized worldwide as the finest bearings, Bearings excellent reason for not just technology, but also includes a sale of a range of services , and to provide knowledge to provide Cylindrical roller bearing value. Here we follow the Bearing bearings distributor in China to understand why the excellent place not only in technology.
Publicity materials in the Group says : rolling bearing is still marked the highest quality , but now the real sense , far more than in the past ." In this regard , President China, explains, "So we are a selling bearings , and now we want to give more and more customers are providing knowledge , provide value . "
While many industries are still bearing a few years ago to imitate their product development , also provide Slewing Bearing financial support for technology development and trying to build economies of scale , is doing and customers to share 100 years of accumulated experience , and philosophy corresponds industry perfect chain , and now their main business covers bearings, seals , lubrication, and services. Data shows , Bearing Group has 35% of the sales revenue from the aftermarket . This shows that Bearing Group has evolved into a knowledge , technology and service companies. is now valued Roller Bearing service and system maintenance, and to provide knowledge and solutions , rather than just selling bearings.
Bearing excellent reason , than just bearing technology in its high-quality , more is to provide customers with solutions that provide knowledge and values as well as pre-sale and after-sale service.

Backing bearings four point angular In different series are available in all of these designs
the larger cross section can be selected and used more carrying capacity without changing the bearing shaft diameter. Thin-walled bearing rings can be designed to require very little space is extremely light and bearings .
Deep groove ball bearings, four point contact bearings, angular contact ball bearings can be thin-walled rings bearing deep groove ball bearings, four point contact bearings, angular Cylindrical roller bearing contact ball bearings. In different series are available in all of these designs. Series depends on the size of the cross section . Match ball and series. Deep groove ball bearings can support axial loads in both directions as well as radial loads. Four point contact bearings can support axial loads in both directions as well as radial loads ; therefore they are in contact with the double row angular ball bearings same operation mode slim bearings can match the optimal number of balls and the contact angle of 30 They support radial loads than deep groove ball bearings or four point contact bearing higher , and can support axial loads from the same direction . For special needs , angular contact ball bearings bearings can also be provided as a match . Thus , rigidity and load carrying capacity of these combinations than single- bearing products to be much higher

Backing bearings new factory started production
bearings distributor in China , according to official reports , bearing brand in Japan , as the Bearing Recently decided to expand production and sales business in China to meet its development needs in the Chinese market .
To keep up with the pace of China's rapid economic growth , with local staff as the center is developing a new strategy - to 2016 sales in China will be doubled. has plans to expand production Thin section bearing and sales plans in China are as follows:
January next year, the heavy industry base in northeast Shenyang , Shenyang Bearings new factory started production , also plans to increase investment and equipment , so that production capacity doubled.
2012 operation began in August new plant to increase investment in equipment ,Bearings sales center in inland Cylindrical roller bearing plant capacity enhancement in the supply Chinese customers , but also to consider the Japanese automobile manufacturers to provide bearings.
3 Seiko will be located in the existing coastal and southern China 18 sales outlets , based on additional sales turnover in the inland area stores , plans 2 to 30 years after the marketing point .
current medium-term plan is to make the Chinese business year 2012 reached 100 billion yen ( 8,000,000,000 yuan ) . However, according to the company the current development momentum , we have achieved one year ahead may be . And, with the rapid growth of the Chinese market , industry and product sophistication , the growth of local enterprises , and the Chinese government 's specific implementation Twelfth Five-Year Plan , China 's bearing demand after five years than the current doubling this requires a corresponding bearing industry has rapidly expanded.

so the stored procedure between the slim section ball bearing must be rust.
for machinery brought huge losses, especially in precision parts such as bearings, etc., resulting in corrosion, not only affect the accuracy and surface roughness, but also reduces the life, but you can not use or even scrapped .
Bearing rust work is an important task, especially rust between processes, such as heat treatment plant slim section ball bearing in pickling, cleaning, after grinding, there are many tapered roller bearing processes. When not using the product water production, a process completed in sequence would be stored in the middle of the library, so the stored procedure between the bearing rings must be rust.
Traditional methods and lack of rust
Methods commonly used inter-process rust bearings are the following:
1 dip tank in rust
The bearing trap immersed stainless steel slewing bearing in 5% aqueous solution of 0.6% sodium nitrite and sodium carbonate, the rust is still good, but a lot of rust tank and other equipment, take up a lot of space management is not easy.
2 dipping concentrated solution of sodium nitrite
After washing the product, immersed in a 15% -20% sodium nitrite and 0.6% sodium carbonate solution, and then it is stacked up. In this way short of its rust, generally only kept 14 days, but in the rainy season, due to wet weather, keeping only 2-3 days
It must be reprocessed, it takes labor and money.
3 oiled paired tapered bearing
Like anti-rust oil painted like a finished product. This method must be cleaned before the next step, more trouble.
