Damage status: FAG bearing load bearing rotates again,BEST Bearing
http://www.bearing-us.com/ 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 FAG bearing clearance is not appropriate. FAG bearing box accuracy is bad, FAG bearing box of large uneven rigidity of shaft deflection of rust, erosion, abrasion and creasing surface deformation phenomenon () the development of the cause.
Measures: check the size of load and again institute FAG bearing improve installation method is used to improve the sealing device, when stop rust. Using the appropriate lubricant viscosity, improving the lubrication method. Check the shaft and the accuracy of FAG 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.
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 the axis, FAG bearing box.
The size of the measures: check the load. Preloading is appropriate. Improve lubricant and lubricating method. Check the accuracy of shaft, FAG bearing box.
