The ZYS ball bearing use of the surface layer of the metal melting and re- solidification

The use of the surface layer of the metal melting and re- solidification , to give the desired composition of the surface hardening treatment or tissue enhancement technique called surface metallurgy . Including the surface from the insoluble alloy or composite powder coatings, crystalline or amorphous surface melting , surface alloying methods. Deep groove ball bearing is characterized by rapid heating to a high energy density , the surface of the metal layer or metal coating on the surface of the alloying material is melted and then solidified by cooling to obtain their particular Bearing life testing machine structure or particular properties of the reinforcing layer . This particular structure is perhaps the crystal structure refinement , or maybe supersaturated phase , metastable phase , even non- crystal structure , depending on the process parameters and methods of surface metallurgy . Rolling industry in miniature bearing surface enhanced laser heating has done research to good effect.
Application of physical or chemical methods , the coating on the metal surface bearing a different material properties of the matrix to strengthen the film , the film referred to as surface railway bearing hardening. It includes electroplating , electroless plating ( chrome, nickel, copper, silver , etc. ) as well as composite plating, brush or transformation processing , including in recent years, the rapid development of high-tech : as CVD, PVD, P-CVD , etc. vapor deposition and ion implantation method to strengthen the film surface enhancement technology ( also known as atomic metallurgy ) and so on. Their common feature is the film can form specific performance in the work surface to enhance the wear resistance of the surface resistance, fatigue resistance, corrosion resistance and self-lubricating properties. Such as ion implantation technology to strengthen the deep groove ball bearing surface , enabling the bearing surface wear , corrosion resistance, and resistance to contact fatigue performance have been significantly improved , so that the service life of bearings KOYO grow exponentially .

Tune concentric with the bearing dimension series varies

Tune concentric with the bearing dimension series varies , generally allow aligning angle is 1 to 2.5 degrees , the larger the load bearing capacity of this type , in addition to radial sealed angular contact ball bearing load bearing can withstand the effects of a two-way axial load , has good impact resistance , in general, low self-aligning roller bearings operating speed allowed .

 City is China's largest spherical roller production bases , one son , now a production capacity of 1.5 million Bearing life testing machine sets of the above , the production range :21304 ,22205 -22,264 -21,320 -22,364 ,22308 ,23120 ,23022 -23,064 -23,264 -23,164 ,23218 ,24022 -24,064 -24,164 ,24128 , cage has CA, MB, MA, CC,  five kinds ; straight holes and the inner cone (K) two kinds ; outer ring ( Tanker ), ( with stopper groove ) two; there are various clearance standards to meet customer needs ; tolerance levels are two kinds.

    After years of development and accumulation , the company is strong in technology , product quality and excellence, by domestic and foreign customers in the domestic market , covering over 30 provinces, municipalities and autonomous regions , as power machinery , mining machinery, textile machinery, engineering machinery and automobile industries, providing supporting services.

    Extend its high-tech products with a long inner spherical roller bearings, spherical roller thrust bearings, spherical roller bearings seals , vibrating screen bearings ; while the company also manufactures bearings, rolling mill bearings, cylindrical roller bearings, taper roller Bearings .

double row tapered roller bearing

Environmental protection is one of today's society a constant topic today,bearings distributor in China and introduce you to the future SKF technology environmental protection. in the maintenance and operational experience in the field helps to make existing operations more streamlined and efficient, and applied to the new design and the concept of alternative energy sources such as theexpertiseBearing life testing machine  and technology is more regarded as extraordinary.
in the wind and other renewable energy sources has extensive experience in the field. For example, an innovative series of  Nautilus bearing solutions enable wind turbine manufacturers to abandon the spindle, thereby reducing the weight of the generator, reducing size and friction, ultimately increase this clean, renewable energy production. SKF bearings, seals and lubrication systems also help extend the life of solar energy equipment, particularly in harsh environments and extreme double row tapered roller bearing temperatures. actuators and control unit helps to make the building self-regulating system blinds warmer in winter, cooler in summer. Such a system equipped with products can reduce HVAC (HVAC) Energy consumption: 30-35% decrease in winter, summer reduced by half.
 Transportation is the use of new technology to improve the environment a key. integrated components (from the engine and gearbox to the final drive and wheel) to reduce friction and reduce weight, thereby helping to reduce vehicle fuel consumption future. For example, for the final drive pinion unit of SKF hybrid can reduce carbon dioxide emissions per kilometer 3 g. In the airline industry applications, adopt a strong and lightweight titanium and other advanced materials integrated components, and the use of wire flight control system, helps to reduce weight and improve fuel efficiency.

In some special operating conditions

In some special operating conditions , deep groove ball bearings can be obtained in a longer life of traditional computing, especially under light load conditions . These special operating conditions is that when the rolling surface ( track and rolling elements ) are effectively separated and limit pollutants may cause damage to the surface of a lubricant film . In fact, under ideal conditions , the so-called permanent KOYO bearing  life is possible.
Rolling of life in revolutions ( or hours to work under a certain speed ) , definition: KOYO bearings within this life , should occur initial fatigue damage ( spalling or defect ) any bearing turbocharger bearings  on their laps or rolling . However, both in laboratory tests or in actual use , can be clearly seen , the same appearance under the same operating conditions of the bearing , the actual life different. There are also a number of  different definitions of deep groove ball bearings , " life " , one of which the so-called " working life ", which represents the actual life of a bearing damage can be achieved before by wear, damage is usually not caused by the fatigue , but is caused by wear and tear , corrosion, seal damage and Bearing life testing machine other reasons .
By mechanical means of the metal surface layer is plastically deformed to form a high hardness and high strength hardened layer , the surface strengthening method called surface deformation strengthening , also called hardening . Including blasting , sandblasting, cold extrusion, rolling, cold- milled and shock , explosion shock processing and so on. Features deep groove ball bearings of these methods are: strengthening layer increased dislocation density , sub- crystal structure refinement, making it the hardness and strength increased , the surface roughness value decreases, the surface can significantly improve the fatigue strength of parts and reduce fatigue notch sensitivity. This enhanced process is simple , the effect is significant , there is no clear boundaries between the hardened layer and the substrate , the structure of a coherent , easy to fall off in use. Most of the methods which have been applied in the bearing industry : rolling surface is applied to strengthen the impact of these methods , precision ferrule RCC has become a new and enhanced processing methods .
