Application on the joint bearing of fibrous fabric of politef


30th November 2010 Bearing Technology 0 Comments
Summary: The fibrous fabric of politef is PTFE, Nomex, glass fibre ' Or sweet-smelling black silk ribbon fiber Wait for materials, adopt the textile of ad hoc manner, and the compound fabric made after special infusion is dealt with, high to have intensity, the characteristic with little coefficient of friction. Apply such fibrous fabric to the joint bearing, make the joint bearing already keep the high characteristic that bears the weight of, adjusts the heart automatically, have it concurrently from characteristics such as the lubricated, shock-resistant, long-life,etc.. This kind of key ...

SKF aviation rolling bearing technology


30th November 2010 Bearing Technology 0 Comments
First, new material of aero-engine bearing 1.M50NiL bearing steel From 1955 to 25 years of 1980, the rotational speed of the bearing of the aero-engine increases steadily, dn value already been up to nearly 2,500,000. Entered the 1990s, high speed and high temperature of the aero-engine put forward higher requirement to the rolling bearing. However, existing bearing steel, even a specialized high temperature resistant bearing steel, such as M50, 18-4-1 and various of 14Cr-4Mo family are derived steel kind, can still work normally at a temperature obviously higher than the bearing of the ...

Forging of the bearing steel


30th November 2010 Bearing Technology 0 Comments
The bearing steels all roll the bearing steel, have high compression strength and tired limit, high hardness, high wearability and certain toughness, it is good to quench the sex completely, it is extremely tight to control sulphur and phosphorus, it is a kind of advanced high-quality steel, can make coldly and make feeling and have steel. Proportion: 7.81. 1 The bearing steel forges the temperature 1Start to forge the temperature: 11501120 The satin temperature of end: 850800 Degree. 2Remove the superficial defect before forging, is trying hard to preheat, heating fast. 3Warm while ...

Bearing steel production status with develop ( One)


30th November 2010 Bearing Technology 0 Comments
A preface The rolling bearing is the important mechanical basic part, it is very extensive to employ in trades such as the space flight, war industry, machine-building, railway transportation and car making,etc.. Precision, performance, life-span and dependability that it has determined to be equipped to a great extent. The bearing steel is the important special steel variety, its pure degree, with organizing the homogeneity to be to influence the important factor of the bearing life-span. GCr15 ball bearing steel containing 1.0% C, 1.5% Cr is most harsh steel kind of quality requirement in ...

Why did defect of casting the base influence the fatigue life of the bearing directly?


30th November 2010 Bearing Technology 0 Comments
Because the bearing steel most important performance is to contact fatigue life. Used as the bearing steel of the axle sleeve and cast the position of base centre and become the surface that the bearing rubs. So such quality defects as the centre where the bearing steel casts the base leans towards analysing, crackle and is mixed with are having important influence on fatigue life of the bearing. Used as the bearing steel of the ball, the centre position of the steel products will become the surface of the ball, the defective impact on its fatigue life of the above-mentioned quality is ...

Bearing steel production status with develop ( Two)


30th November 2010 Bearing Technology 0 Comments
Impact on bearing steel quality of 5 carbide The impact on fatigue life of carbide is very obvious. Especially with smelt, casting progress of technology, oxygen content and oxide mixed with content under the very much low situation in steel, the function of the carbide seems even more important. Particle size of 5.1 carbide and influence distributed The particle size, shape, quantity and distributing the state of the carbide influence fatigue life. The bearing factory requires the carbide particle is tiny in the steel products of bearing, shape rule, and is distributed evenly. When there is ...
