WebAug 23, 2024 · Leaky Seals. Bearing seal leaks can be traced to three basic causes: Condition and size of the shaft and housing bore. Poor installation practices. Contamination. The most common cause is a worn or scored shaft, most often the result of abrasion caused by contamination. The shaft should be replaced or repaired to prevent seal damage. WebAug 21, 2024 · Different compressor designs and bearing arrangements were briefly discussed. The main failure mode of rolling bearings lubricated with refrigerant–oil mixture (surface distress) was discussed in detail. A model to predict surface distress from poor lubrication conditions was explained with the application to carbonitrided bearings.
