Grease lubricated sealed bearings in advance of filling grease in sealed, as well as inside the shell filling grease in moderation, at regular intervals to supplement or replace the filling time for fat. In addition, there are multiple IKO bearings require lubrication of machinery, pipe connected to the central lubrication grease. Grease lubrication can be achieved long after filling a grease does not need to supplement, and its sealing device structure is relatively simple, so is widely used. Oil lubrication is relatively simple. Lubrication can often improve the micro-bearing service life.
Imports bearing on a allow a slight operating noise, if the noise is too large or abnormal noise or impact sound, it indicates that the bearing is faulty.
Causes of rolling bearing noise is more complex, one is the inner and outer ring of mating surfaces of the bearing wear. Because of this wear, damage bearings, IKO bearings and shaft fit and shell, lead to deviate from the correct position of an axis, axis at high speed movement generated noise. When tired of miniature bearings, metal Flake on its surface, also makes the abnormal noise of radial clearance of bearings increases. In addition, insufficient lubrication of the bearing, forming dry friction, as well as the bearing crush will produce abnormal noise. Bearing wear loose after the exclusion, cage loose damage, also have a strange sound.
Agency operation, installation of bearing parts to allow a certain degree of temperature, when you touch body shell with their hands, should not feel hot as normal, but it indicates that the temperature is too high.
Bearing high temperature are: quality does not meet the requirements or modification of lubricating oil, lubricating oil viscosity is too high; body fitted too tight (insufficient clearance), miniature bearing Assembly too tight; bearing washer on the shaft or rotating; load too large; or rolling bearing cage fragmentation.
Selection and control of shaft and housing tolerances: after the bearing pressed into the bearing should rotate flexible non-blocking. If there is a clear turning not flexible, it indicates that the axis dimensions are too big, tolerance to downgrade. IKO bearings pressed into axis hands spin when there is a clear "rustling", the tolerances of the shaft may be too large or the roundness of the shaft well. So in the control shaft and housing tolerances, to control the roundness, at present, many manufacturers to control the tolerance, not to control the roundness.
Miniature bearings are high-precision products, such as improper
Assembly can easily cause damage to the bearing Raceway, cause bearing damage. Bearing Assembly should have a special mold, not free to strike, only small forces when pressed into the shaft, pressure only when large washers. Assembly requires the use of pneumatic or hydraulic, touched up and down when the pressure external to the level, such as the tilt can cause mechanical damage of bearing Raceway, while cooling the bearing rings. Many manufacturers are considered to be before bearing problems, through our continuous publicity, motor works have been realized largely insulated paint problem now. Insulating varnishes containing the problem is because of volatile acid in formation under certain temperature, humidity, corrosive substances, corrosion, which cause bearing damage IKO bearing Raceway. That there can only be a good selection of electrical insulating varnishes, and after drying, ventilation Assembly over time.
