Bearing's role is to make the stationary ring of the bearing and rotate the circle respectively and the static parts of the mount (usually bearing) and rotating parts (usually the axis) with consolidation, enabling the rotation passed load and limited movement system relative to the stationary system the basic tasks of the position.
Circumferential surfaces of bearing rings should have good support and force evenly to reduce distortion and can give full play to the carrying capacity of the bearing;
Bearing rings cannot be sliding along the tangent at its surface, doing so could damage the mating surfaces;
Free-end bearing must be commensurate with the length of the shaft and housing bore change, which must have the ability to adapt to swim axial position within a certain range;
Bearing installation and removal must be made easier to achieve labor saving, saving of time and costs.
Taking advantage of the bearing distribution tie is very good, I hope that, in the selection of fully taking into account the above four points.
Is grease lubricated bearings and double-sided with seals or shields, bearing before installation of the seals without cleaning. Checking the size and finishing of related parts.
1 grease lubrication
Relubrication of the bearing is the best in equipment downtime during implementation of the plan, and added on a regular basis, at the same time, cleared the old oil or through the drain the old oil out. Before joining fresh fat injection inlet should be clean. If the housing is not glib, you should open the housing cover or cover in order to remove the old grease, after cleaning, add fresh oil of the same model.
2, are lubricated by lubricating oil
Regularly check the oil level and oil lubricants, under normal circumstances, the normal oil level oil level Windows for devices within ' or ' 1/3-2/3. Cup of the oil supplement method for oil, their ability to display fuel level represents only oil supplement, housing the oil level is to meet operational requirements, the oil level in the oil Cup less than one-fourth could be considered to make up the total volume of oil.
Check and fill oil, removed a small amount of lubricating oil as Lube samples and fresh compared to units can be in a position to consider oil quality testing is done in order to ensure the quality of qualified. If sample looks like cloud, then the results may be mixed with water, that is, we often say that oil emulsification, lubricant should be replaced at this time.
If sample way dimming or changing the color of thick, so may indicate that the oil has begun to carbide should be completely replaced the old lubricant. If possible, use fresh lubricant to rinse the circuit. When replacing the oil, should make sure that the replacement of oil the old and the new of the same model, and meet the requirements of supplement the oil level.
