Detection of KOYO bearing grease is effective method

In the using process of KOYO bearings, grease the effect is very critical, if use bad grease, should not have effect not only, but also import bearing damage, reduce its service life. So how to detect the validity of bearing grease is the significant particularly important. A, KOYO bearing grease oil flow observation to find two cups, one would need to be checked out of the lubricating oil, empty on the desktop, the other will leave the measuring cup with lubricating oil for high 30 - desktop 40 cm and tilt, let oil flow slowly to the empty cup, to observe the flow situation, good quality lubricant oil flow should be long and thin, uniform, continuous, if appear oil flow fast and slow, and sometimes has a large flow, the said lubricating oil has deteriorated. Three, KOYO bearing grease oil droplets trace method to find a clean white filter paper, number of oil drops on the filter paper, after waiting for lubricating oil leakage, if the surface is black powder, touch resistance acerbity feeling, is the lubricant inside has many impurities, good oil powder, with the hand feels dry, smooth, and yellow. Second, KOYO bearing grease hand twist method be twist lubricating oil between the thumb and forefinger grinding, good lubricating oil hand feel less lubricity, wear debris, no friction, if feel fingers between the larger friction feeling such as sand, suggests that the impurity, lubricating oil can no longer use, a new lubricating oil should be replaced. Four, KOYO bearing grease illumination method when the sunny weather, use a screwdriver to lubricating oil lifted, and the horizontal Angle of 45 degrees. Contrast sunshine, observe the oil situation, under the light, can see clearly without wear debris in lubricating oil is good, can continue to function, if excessive wear debris, lubricating oil should be changed. Bearing. The following of defects, it can no longer continue to use the new bearing should be replaced immediately. Specific as follows: ( 1) Bearing inner ring and outer ring, rolling element and cage have crack or gap on any one; ( 2) Bearing ring, rolling body on any fracture; ( 3) Bearing raceway surface, guard, with significant roller card injury; ( 4) Bearing cage wear significantly, or rivet significant relaxation; ( 5) On the raceway surface, rolling element bearing with rust and injury; ( 6) On the raceway surface, rolling element bearing has serious indentation and mark; ( 7) Bearing inner ring diameter or outer diameter surface has obvious creep; ( 8) Due to the hot color is obvious.
