The world's largest bearing manufacturers Reading

SKF Chinese transliteration of the name "SKF", insert ball bearing ,Company Headquarters: Gothenburg, Sweden; SKF brand still stands for the highest quality rolling bearings, but now the real sense, far more than ever before.

SKF bearing production accounted for 20% of the world's total output of similar products. Group was founded in 1907, in the rolling bearing and seals business is a global leader in products, customer solutions and services suppliers, SKF early in 1912 to enter the Chinese , turbocharger bearings in Shanghai established the first office in China in 1916 set up the first sales company, SKF in 1986 and returned to China, in Shanghai set up a consignment station, and another in Shanghai, Beijing, Guangzhou, Chengdu, Dalian, Nanjing, Xi'an, Wuhan set up offices in Beijing and set up a consignment station.

Three kinds of bearing forms,Sleeve Bearing,Ball Bearing and two kinds of bearing forms mixed

The bearing type is the bearing type used by the air cooling radiator fan. In mechanical engineering, the type of bearing is very much, Wind turbine bearing but used in the radiator products bearing the form in accordance with the basic working principle of the classification so three using sliding sleeve bearing sleeve bearing and rolling friction of the ball bearings (ball bearing) and two bearings form with the use of the three hybrid.

Ball bearing changed the bearing friction, rolling friction is adopted, the more effectively reduces the friction phenomenon between the bearing surface, effectively enhance the service life of the fan bearing, high speed bearing and therefore will prolong the service life of the radiator. The disadvantage is that the process is more complex, resulting in higher cost, but also bring higher working noise.

Angular contact ball bearings and cylindrical roller bearings under load

Always bearing the opposite direction of the axial load, mounting angular contact ball bearings. Machine tool spindle angle contact ball bearing contact angle for 15 degrees and 25 degrees two kinds, Wind turbine bearing the contact angle of 15 degrees for high speed, axial load is small.

Cylindrical roller bearings can bear large radial load, can not bear the axial load. Single and double row cylindrical roller bearings, sealed angular contact ball bearing precision machine tool spindle is the most common cylindrical roller bearing inner hole with 1:12 taper double row cylindrical roller bearings NN30K (old code 3182) series.

Lubricant and application of wind turbine bearing

Wind turbine bearing lubricant is special organic thickener thickening synthetic oil, and add a variety of high-performance additives and refined oil.

Wind turbine bearing lubricant characteristics,
Excellent high temperature performance, especially high-temperature performance particularly advantageous;
Excellent water resistance, rust resistance and oxidation resistance;
Good oxidation resistance, sealed angular contact ball bearing to ensure long-term performance at high temperatures;
Good corrosion resistance, to ensure that the bearing parts are not corroded.

Applications,
Fan bearing lubricant for high temperature, high or cold temperature zone and field work over rolling bearings above 200 ℃ wide temperature range work. Such as air motors, electrical, clutch thrust bearings, high temperature fan, racing wheel bearings, plastic stretching tenter, polyester heat setting machine, resin finishing machine, molten salt pump motor, Cross roller bearing loop steamer machine, high temperature dyeing tanks, steam it machine, shrink machines and other high-temperature operation running bearing lubrication.

Temperature range, -60 ℃ ~ + 250 ℃, short-term up to 300 ℃.
