Contact fatigue spalling occurs in INA bearing surface

Contact fatigue spalling occurs in INA bearing surface , often accompanied by fatigue cracks , first produced from the contact surface of the following maximum alternating shear stress , and then extended to the formation of different surface flaking shapes, such as point-like pitting or pitting as spalling , flaking into small pieces turbocharger bearings called superficial peeling. Due to the gradual expansion of flaking surfaces , but often extend to the deep , forming deep peeling. Deep contact fatigue spalling is a source of fatigue failure .
Continuous wear will cause spherical grinding spindle roller thrust bearing parts gradually damage and eventually lead to the loss of dimensional accuracy INA bearings and other related issues . Wear may affect the shape change , with the gap increasing and work surface morphology changes that may affect the lubricant or it reaches a certain level of pollution caused complete loss of lubrication , which makes bearings and even the loss of rotational accuracy can not operate normally . Wear failure is one of the kinds of bearings common failure mode, press the wear is usually divided into the most common form of abrasive wear and adhesive wear .

Currently SKF Solution Factory business includes spindle repair center

Yesterday,bearing distributor in China through the Swedish SKF Group's global video conference was informed yesterday, in France Montigny's SKF Solution Solution program officially opened the factory to run, which is the eleventh in the world SKF Solution Factory, which aims to integrate SKF's five large platform engineering capabilities sealed angular contact ball bearing to better serve our customers and create value.
 Solution Factory opened in France, not only for SKF lay the foundation for regional development super-precision bearing in France, and more importantly, through the use of SKF's knowledge engineering and the five  hundred years of technology platforms, is the customer's development of more reliable, more cost-effective for customers to create a direct value. Currently  Solution Factory business includes spindle repair center, lubrication application  center, SKF Bearings restructuring customized services, repair tools repair services and training services, and will soon be extended to remote condition monitoring and rapid seals customized services.
 France Sales Service Manager Mr. Benoit de Dorlodot  Solution Factory France, spoke on the opening ceremony: "We are very pleased to be able to support the French SKF Group SKF Service Department, established in France, the French SKF Solution Factory, which will likely soon improve productivity and SKF in France to provide customers with product reliability, while providing customers with solutions for the French Ministry of SKF direct benefits.

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

Solid state phase transition, by the method of rapidly heating the surface layer part of the surface hardening treatment is called a heat treatment , known as surface hardening . Including flame hardening , high ( in ) frequency induction heating quenching, laser heating or electron beam heating quenching. KOYO bearing characteristics of these methods are: local heating surface hardening , the workpiece deformation ; heating surface profile measurement speed, high production efficiency ; heating time is short, very slight surface oxidation and decarbonization . This method especially for improving the wear resistance to withstand certain impact loads and fatigue strength effects of large and extra large bearing parts significantly .
The use of certain elements into solid state diffusion to change the chemical composition of the metal surface layer , deep groove ball bearings to achieve surface hardening method called chemical heat strengthened, also known as diffusion heat treatment . Including boriding metals , carburizing and carbonitriding , nitriding and nitrocarburizing , sulfide and Sulphonitrocarburizing , Chromizing High speed Spindle , aluminized and chrome aluminum silicon permeation , diffusion  layer graphite , etc. , a wide range of different characteristics . Or dissolved  into the matrix metal element forming a solid solution with other metals or elements  to form compounds. I.e. short change the chemical composition of the elements into the surface layer , and a different phase structure can be obtained . Surface treatment process and carburizing bearing KOYO bearing sleeve nitrided steel parts are enhanced handling this type of fortification .
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 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.

bearing stick asymmetric spherical roller

Thrust roller bearings for axial load mainly axial , radial joint load , but the radial load should not exceed 55% of the axial load . Other thrust roller bearings, such bearings lower friction coefficient , high speed, and aligning performance .
29000 , bearing stick asymmetric spherical roller , the roller can reduce the relative sliding and rolling  in the work , and the roller length , large diameter roller quantity, high load  capacity, usually oil lubrication individual low speed available greased . In the design selection , should be preferred ;
80000 -type cylindrical roller Wind turbine bearing thrust bearings , 90000 Thrust tapered roller bearings and needle roller thrust bearings AXK type , can withstand a one-way axial load, it is much larger than the thrust ball bearing axial load capacity and rigidity, small axial space occupied .
Thrust cylindrical roller bearings and thrust roller bearings for low speed applications , thrust tapered roller bearing speed slightly higher than the thrust cylindrical roller bearings.
Thrust cylindrical roller automotive bearing bearings  are separable bearings, can withstand axial load and a slight impact, to limit the axial displacement ( or shell ) in one direction , and therefore can be used as a one-way axial positioning . But its carrying capacity is far greater than thrust ball bearings. Roller rolling , because the roller ends of lines at different speeds , so that the rollers in the ring raceway sliding inevitably arise , therefore , such a bearing speed limit lower than the thrust ball bearings , normally only for low speed applications.
Standard design thrust cylindrical roller bearings with machined metal solid cage, according to user requirements , but also other types or materials cage. Thrust tapered roller bearings can withstand axial load, can limit the axial displacement of the bearing , it can be used as a one-way axial positioning . And thrust cylindrical roller bearings compared to carrying capacity, relative sliding is small, but the lower speed limit
