Common Problems And Installation Methods Of Iko Imported Bearings

Common Problems

It is common for IKO imported bearings to fail during operation, so there is no need to make a fuss. In case of failure, judgment and Common Problems treatment are the key. Today, we will explain the common faults of bearings and troubleshooting methods.

1. The temperature of IKO inlet bearing is too high

During the operation of the mechanism, the part where the Common Problems bearing is installed is allowed to have a certain temperature. When touching the mechanism shell by hand, it should be normal not to feel hot. Otherwise, it indicates that the bearing temperature is too high.

The reasons for the high temperature of IKO imported bearing are: the quality of lubricating oil does not meet the requirements or deteriorates, and the viscosity of lubricating oil is too high; The mechanism assembly is too tight (insufficient clearance); The bearing assembly is too tight; The bearing race rotates on the shaft or in the shell; Excessive load; IKO imported bearing cage or broken body, etc.

2. IKO inlet bearing noise

IKO inlet bearing is allowed to make slight running sound during operation. If the sound is too loud or there is Common Problems abnormal noise or impact sound, it indicates that IKO inlet bearing is faulty.

The reasons for the noise of IKO imported bearings are complex. One is the wear of the mating surfaces of the inner and outer rings of the bearings. Due to this wear, the matching relationship between IKO imported bearing and shell, bearing and shaft is damaged, resulting in the axis deviation from the correct position and abnormal sound when the shaft moves at high speed.

When the bearing is tired, the metal on its surface will peel off, which will also increase the radial clearance of IKO inlet bearing and produce abnormal noise. In addition, IKO imported bearings have insufficient lubrication, resulting in dry friction and bearing breakage, which will produce abnormal sound. After the IKO inlet bearing is worn and loose, the cage is loose and damaged, which will also produce abnormal noise.

Common Problems And Installation Methods Of Iko Imported Bearings

Installation method of IKO imported bearing

The fit between IKO inlet bearing and shaft is generally transition fit, and the fit between seat ring and IKO inlet bearing seat hole is generally Common Problems clearance fit. The middle shaft ring of two-way bearing shall be fixed on the shaft to prevent rotation relative to the shaft.

The installation method of IKO imported bearing is generally shaft rotation, so the fit between inner ring and shaft is win-win fit, and the fit Common Problems between bearing outer ring and IKO imported bearing chamber is clearance fit.

When installing IKO imported bearing, the verticality of shaft ring and shaft centerline shall be inspected. The method is to fix the dial indicator on the end face of the box shell so that the contact of the dial indicator is Common Problems against the raceway of the shaft ring of IKO imported bearing, rotate the bearing and observe the pointer of the dial indicator.

If the pointer deviates, it indicates that the shaft ring and the shaft centerline are not perpendicular. When the shell hole is deep, it can also be inspected with an extended dial indicator. When the IKO imported bearing is installed correctly, its seat ring can automatically adapt to the of the body to ensure that the body is located in the raceway of the upper and lower rings.

If it is installed reversely, not only the IKO imported bearing does not work normally, but also all mating surfaces will be seriously worn. Since the Common Problems difference between the shaft ring and the seat ring is not obvious, extra care should be taken during assembly.

In addition, a clearance of 0.2-0.5mm shall be reserved between the bearing race and the bearing seat hole to compensate for the error caused by inaccurate processing and installation of parts. When the center of IKO inlet bearing ring is offset during operation, this clearance can ensure its automatic adjustment, avoid contact friction and make it operate normally. Otherwise, the IKO inlet bearing will be severely damaged.
