FANADE Industry(HongKong) Ltd,a professional distributor of supplier of Fag spherical roller bearings http://www.fagbearings-hk.com/Fag-Spherical-Roller-Bearings.html,owns a state-level enterprising technology center,and has developed more than 200 kinds of new products on the annual average ranging from Deep groove ball bearings,self-aligning ball bearings,thrust ball bearings,angular contact ball bearings,tapered roller bearings,cylindrical roller bearings,spherical roll bearings etc with imported and domestic famous brands including Swedish SKF bearings,German FAG,INA bearings,Japanese NSK bearings,Japanese NTN bearings,Japanese KOYO,FYH bearings,Japanese IKO bearings,American TIMKEN bearings,Britain RHP and other famous imported bearings.For decades,the company has established and completed the quality management system of scientific standardization which has passed the quality system certification,with the quality management system in line with international standards.In 2005 they won the title of Chinese famous brand.Here we'd like to talk about Analysis of the bearing damage status.
　　Damage status: SKF bearing load bearing rotates again, inner ring and outer ring raceway surface or rolling decent present designed stripping due to rolling fatigue phenomenon.
　　Reason: too much load. Bad installation (non linear) torque load foreign invasion, into the water. Poor lubrication, lubricants inappropriate SKF bearing clearance is not appropriate. SKF bearing box accuracy is bad, SKF bearing box of large uneven rigidity of shaft deflection of rust, erosion, abrasion and creasing surface deformation phenomenon () the development of the cause.Analysis of the bearing damage status。
　　Measures: check the load and the size of the institute, again using SKF bearing improve installation method to improve the sealing device, when stop rust. Using the appropriate lubricant viscosity, improving the lubrication method. Check the shaft and the accuracy of SKF bearing box. Check the clearance.
　　skinning
　　Damage status: present a dark side, with a mild wear dark surface from the surface of multiple deep down inside to tiny cracks of 5 to 10 m, and on a larger scale slightly off (the tiny stripping)
　　Reason: the lubricant is not appropriate. Foreign body into the lubricant. Lubricant bad cause surface roughness. Matching rolling parts surface finish is not good.
　　Measures: improve sealing device to improve matching rolling lubricant selection of parts surface finish.Analysis of the bearing damage status.
　　Card injury
　　In the injury is due to the damage state of sliding surface injury parts of small burns summary of surface damage. Slide face, rolling surface circumferential direction of linear scars. End of the roller set linear scar near the end of the roller shaft torus card.
　　Reason: too much too much load, preloading. Bad lubrication. Foreign body nip. The inner ring of the outer ring tilt, the deflection of shaft. The precision of shaft, SKF bearing box.
　　The size of the measures: check the load. Preloading is appropriate. Improve lubricant and lubricating method. Check the shaft, the accuracy of SKF bearing box.
　　The fracture
　　Damage status: fracture refers to the roller Angle of groove wheel rim or on the local part are exerted impact or excessive load and a small number of fracture.Analysis of the bearing damage status.
　　Reason: when installation has taken a knock. The load is too large. Using bad fall, etc.
　　Measures: to improve the installation method (using hot charging, using the appropriate tool holder). Correct the load conditions. SKF bearing installed, supporting to guard.
　　Crack, crack
　　Damage status: crack refers to the crack damage raceway wheel or roller. If continue to use, will also include the development of the crack fracture.
　　Reason: greater than surplus quantity. Too much load, impact load. Stripping. Because of the raceway contact of wheel and install components of fever and micro vibration wear. Fever caused by creep. The cone shaft taper Angle. Axis of the cylindricity. Steps of the shaft radius is bigger than SKF bearing chamfer and cause interference with SKF bearing chamfer.Analysis of the bearing damage status.
　　Appropriate measures: interference quantity. Check the load conditions. Improve the installation method. The shape of the shaft to appropriate.
　　indentation
　　Damage status: bite into a tiny metal powder, foreign bodies, such as on the raceway surface or rotating the dent. Due to impact, such as the installation on the roller spacing interval to form the concave (brinell hardness indentation).
　　Reason: the foreign body nip of metal powder etc. Assembly or transport process under impact load is too big.
　　Measures: shock collar. Improve the sealing device. Filter the lubricating oil. Improve assembly and method of use.Analysis of the bearing damage status.
　　Pear skinning pitting
　　Damage status: the weak glossy dark on the surface of the raceway pear peel pitting.
　　Reason: the foreign body nip appeared in the process of lubrication. Due to the moisture in the air and condensation. Bad lubrication.
　　Measures: to improve the sealing device. Fully filter lubricating oil. Using the appropriate lubricant.
　　Wear and tear
　　Damage status: the so-called wear is caused by friction of raceway surface or rolling surface, roller ends, shaft ring surface and maintains a concave surface of the wear and tear.Analysis of the bearing damage status.
　　Reason: foreign invasion, rust electric erosion caused by development. Bad lubrication. Due to the irregular motion of rolling body caused by the skid.
　　Measures: to improve the sealing device. Wash the SKF bearing box. Fully filter lubricating oil. Check the lubricant and lubricating method. To prevent the non linear.
