August 16, the reporter walked into the workshop Bearing Co., Ltd. Shandong Chaoyang, I saw a piece of steel after heating, cutting, stamping, more than 10 processes into one shiny bearings. However, in this seemingly simple line, the sun bearing the company through its own research and development of self-aligning clutch release bearing units, will improve the accuracy of bearing curvature to 3 microns (1 millimeter equals 1000 m), reached the advanced level.
In the bearing industry oversupply, intense domestic competition, foreign transfer to the domestic production, especially under the background of the slowdown this year, the sun bearing to produce a excellent answer, they produce gearbox bearings, engine bearings and other products selling more than 20 provinces and cities and exported to European markets. The first half of corporate sales exceeded 80 million yuan.
"This is due to our assiduous core competitiveness. Precision bearings curvature of 10 microns can be listed money, but business development can not be complacent, and only rely on innovation, in order to continue to grow." Wan Yong, general manager of Chaoyang bearing company said.
Overcome technical problems
Deputy General Manager, economist Lee Chang describes the traditional automobile clutch bearings produced by hand grinding wheel, can not achieve self-aligning bearing of 360 degrees (that rotates 360 degrees), it is prone to failure, and the dismantling of trouble, spend hours . It is also within the industry has been difficult to break problems. In 2012, the company set up by Lee Chang headed the research team, concentrate overcome this problem. "We continue to revise the design parameters of bearings, each producing a sample, you get the Luoyang Bearing Research Institute tested dozens of times a year test." Li Chang said.
In early 2013, the independent design and development of new self-aligning clutch release bearing unit successfully tested. The production technology used within the bearing and wave spring retaining ring installation can be achieved self-aligning bearing 360 degrees. In addition, the use of stainless steel roller bearings were finalized, will improve the accuracy of curvature to 3 microns, application performance to the domestic industry-leading level.
Targeting high-end industry
"Enterprises should grow, it is necessary to diversify from a single product, out of the vicious competition in low-end products." Wan Yong said. Since 2007, the company annually in improved technology, investment in equipment on more than 10 percent of sales, it is thanks to continuous innovation, product by including Qingdao Green special, Foton, Shenyang Jinbei, including multi- domestic well-known enterprises of all ages.
In the bearing industry, the highest tech engine bearings, engine bearings have, we have the right to speak in Chinese bearing industry. To enter the engine bearing production, the company transferred technology backbone set up R & D team, invested more than 500 million purchase of two processing bearing automatic production line, not only to enhance the accuracy, but also improve productivity. At present, the company has developed five models of engine bearings, mainly used tricycle, four-wheel electric vehicles, light trucks in the field.
Deepen research cooperation
"Science and technology are primary productive forces, the company's inception to determine the 'to science and technology,' the purpose, and actively seek to cooperate with the industry leader in the unit." Wan Yong said.
Wan Yong said unit is a leader in Luoyang Bearing Research Institute, which is the domestic bearing industry authority. In 2007, the company sent several Luoyang sunrise consultations with Luoyang Bearing Research Institute of intent signed a cooperation agreement in 2010, the two sides formally cooperate. Luoyang Bearing Research Institute experts regularly to business training, business will be organized each year, more than 10 technical staff to Luoyang learning, covering design, development, production technology, a check found other aspects. In addition, they also met with Shandong University established a partnership to focus on the development and application of new materials, and provide a small pilot test platform for new projects. Last year, the company applied for patents, patent applications 3 this year, R & D results appear.
