Causes and consequences of malfunctions

Recently, double-row closed compressor bearings that do not require maintenance are becoming more and more common in cars.

They fail due to the following reasons:

• normal wear and tear and part failure due to prolonged use;
• strong belt tension;
• lack of lubricants.

Car enthusiasts need to understand one simple thing: the noise that you hear due to bearing wear is just a consequence of heat and lack of lubrication. After all, the part is experiencing strong and constant loads, raising the temperature of the case to the factory values. If, after disassembling, take the removed bearing in your hands, you will see a blue tint on the separator.

Defective conditioner bearing can be “guessed” by sound

The reason for the overheating is clear: the lubricant thickens and its volume is not enough for the normal functioning of the part. As a result, the balls heat up, break the metal cage, and the bearing wedges.

But even this is not the main problem, because it becomes only the beginning of the appearance of many other faults. For example, a compressor oil seal fails or a coupling closes and breaks. The latter happens due to the burning of the insulation material of the winding.

In addition, if with the replacement of a bearing they tightened, it happens that there is not just a jamming, but also a scrolling of the part in its own socket. Thus it comes to the fact that the notch reaches several millimeters, and this, of course, is not great.

In most cases, the verdict of the masters from the service center will be disappointing - at least the replacement of the front part or even the entire compressor is required. This is that serious trouble, to bring to which you definitely should not.

Because if you do nothing, the belt will suffer next, and if you break it, breakage of wiring or more global faults, up to dents on the hood of the car, are not excluded. Sometimes scrolling of a wedged bearing in a seat leads to excessive vibration of the water pump, generator or other equipment.
