KOYO outer spherical bearing in the working process; the fruit shows abnormal heat, oscillation and noise suddenly increased appearance; marked KOYO outer spherical bearing can be damaged now; should be timely reviewed and analyzed the reason. Professor Analyzed pointed out that there are several common types of damage the way: /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Cracks and cracking data defects and heat treatment are not appropriate; cooperation interference is too large; combined depiction is not appropriate; if the bearing surface has grooves to induce stress concentration; will constitute the ring crack and crack.
The current corrosive current passes through the bearing; a small electric spark will occur; the external part of the touch will be annealed to present a small pit or black highlight. The severe entry will present a large pit.
Shedding is exhausted on the raceway or tumble surface of KOYO outer spherical bearing; because the effect of alternating load causes the surface of the touch surface to fall off in a sheet form; and gradually expands to form a pit. If it continues to work, it will constitute an area shedding area. Because the device is not properly or the bearing housing hole and the centerline of the shaft are skewed, etc., the partial area of ​​the bearing will be subjected to a large load and the early fatigue damage will occur.
The cage damages the tumbling bearing; especially the high-speed bearing; because the smoothing agent is missing; the wearer and the roll or the ferrule touch point wear, bump, and even cause the cage to crack.
Wear when KOYO outer spherical bearing seal is not good; make dust or particulate matter into the bearing; or poor smoothness; it will cause severe scratch or wear on the touch surface; and increase the oscillation and noise of the bearing.
The indentation enters the bearing when the external hard particles enter the bearing; and presses between the rolling body and the raceway; the tumbling surface can be formed into an indentation. In addition, the excessive impact load can also cause partial plastic deformation of the touch surface to form a pit. When the KOYO outer spherical bearing stops; even if the load is very heavy, the fat car is annoyed and the step is arrogant.
Corrosion of water or acid, alkali, salt and other intrusion into KOYO outer spherical bearings or smoothing agent selection will lead to bearing corrosion; fine bearings even if the slight corrosion will make the bearing invalid.

The result of the SKF bearing oscillation is to determine the oscillation of the bearing and the temperature of the bearing.
