Fag bearing maintenance cleaning, automobile damping plane bearing manufacturers tell you

Maintenance of fag bearing

In order to distinguish whether the assembled fag bearing can be reused, it should be inspected after the fag bearing is cleaned. The customized American shock absorber bearing should carefully check the dovetail guide surface, overturning surface, mutual matching surface, the damage of ball bearing, the improvement of fag bearing side clearance, whether there is any damage abnormality caused by the reduction of precision of relevant specifications. For non separated small ball bearings, one hand is used to level the inner hole rotate the outer side to determine whether it is smooth .

1. Oil bath moistening

Oil bath lubrication is the most common lubrication method in fag bearings, which is suitable for low medium speed rolling bearings. A part of the rolling bearing is immersed in the groove, the grease is taken up by the rotating rolling bearing parts, then flows to the management center the oil level should be slightly less than the minimum turning body.

2. Spray moistening

Using dry air to compress the mixture of sprayer grease to produce welding fumes. In the FAG bearing, the cyclone Zhejiang plane pressure bearing can reasonably reduce the temperature of the FAG bearing avoid the slag invasion. This method is suitable for lubrication of high-speed high-temperature bearing components.

3. Spray moistening

The high pressure oil is injected into the fag bearing by the gasoline pump through the nozzle, the oil injected into the rolling bearing is injected into the oil groove through the other end of the rolling bearing. When the fag bearing is running at high speed, the overturning body ball bearing also make the surrounding gas generate cyclones at a very high rotation rate. It is difficult to send the grease to the fag bearing by the general lubrication method. At this time, the grease must be sprayed into the rolling bearing by means of high pressure gushing. The nozzle should be placed between the inner hole the ball bearing management center!

4. Oil leakage lubrication

Oil leakage lubrication is suitable for fag bearing components that must be supplied with grease quantitatively. The amount of oil leakage is generally one drop every 3-8 seconds. Excessive residual oil will cause the temperature of fag bearing to increase.

5. Oil lubrication of circulating system

Use the gasoline pump to transfer the filtered oil to the fag bearing components. According to the grease after the fag bearing, the forson suspension bearing is wholesale, filtered refrigerated before application. Because the circulating system oil can bring a certain amount of heat to reduce the temperature of rolling bearing, this method is suitable for fag bearing components with high speed.

Cleaning of fag bearing

When dismounting the fag bearing for maintenance, record the appearance of fag bearing, determine the residual amount of lubricating fluid, wash the rolling bearing after sampling checking the lubricant used. As a cleaning agent, the general application of automotive gasoline, gasoline.

The cleaning of the unloaded fag bearing includes coarse cleaning fine cleaning. Each of them is placed in the vessel, the metal material mesh is laid first to prevent the fag bearing directly contacting with the dirt of the vessel. During rough cleaning, if the fag bearing rotates with dirt, it will damage the fag bearing overturning surface, which should be paid attention to in many aspects. In the rough cleaning oil, the application of soft brush to eliminate grease, adhesion, about clean, to fine cleaning.

Fine cleaning is to carefully clean the fag bearing while rotating in the cleaning oil. In addition, clean oil should always be kept clean.
