From color, touch, look at three points to identify maintenance effect of bearing

Bearing oil good or bad bearing on bearing service life, so we have to check the oil on a regular basis, oil deterioration occurs, a timely replacement. Check that the lubricating oil is bad? The three detection methods are simple: colour, twisting mill law, oil-spot method.
Normal bearing lubricant to the Brown and dark blue. If the bearing lubricant cream, then mixed with water, continue to use is to just serve good lubrication, we should consider replacing the oil.
But if if is dark, it means that has seriously gone bad, we must be replaced in a timely manner.
Remove some oil from the low oil-pan, applied to the fingers, use your fingers and thumbs twisting mill. If it feels like water, oil-free sense of viscous, that has changed.
If twisting mill can be seen on the fingers after small shiny metal grinding, which indicates that the engine might have a more serious wear and tear parts, and also sets out the engine oil must be replaced immediately.
ECM bursts oil stir drops on white paper (preferably paper), form the oil patch, oil patch after about 2-3 hours gradually from the Center outward proliferation, forming three concentric rings. According to the three regional patterns of colors, widths, and can distinguish the oil State.
Oil lubricated bearing parts suitable for quantitative supply lubricating oil, oil drops of one drop every 3-8 seconds, too much oil will cause increased bearing temperature.
Pump the filtered oil to the bearing parts, bearing after the adoption of the lubricating oil filter cooler for later use. Due to the circulating oil can take a certain amount of heat, to cool off the bearing, therefore bearing part of the law applicable to high speed.
Using dry compressed air sprayer mixed with lubricants to form oil mist, Jet bearing, air can effectively cool the bearing and prevent intrusion. This method is suitable for high-speed, high-temperature lubrication of the bearing components.
