One, in the Japanese NSK bearing before the installation, should use the appropriate measurement tools according to the design drawing the technical requirements of the regulation, check the shaft and a hole and the relevant parts processing quality (such as size accuracy, the shape accuracy and surface roughness, etc.).
Second, the shaft and housings hole on the surface such as a assembly bruise, burr, rusty spot or solid particles, such as abrasive dust, dirt and sand) exist, not only can make Japan NSK bearings in installation and make installation position is not correct, and solid particles such as fall into Japan in NSK bearing the abrasive, when Japan NSK bearing rotates will wear injury or a scratch NSK bearings work surface of
Japan, so before installing must be carefully checked, such as the discovery of the defect, be amended. For example using oil file to remove burr, convex touch the mark, rusty spot, and fine sand cloth lighting, and as cleaning solid particles, dirt, etc.
Three, the assembly should be in a clean surface of gasoline, kerosene, toluene, xylene or cleaning solution clean, dry and clean duster cloth, besmear again putting a thin layer of oil, so can make installation operation more convenient.
Four, the Japanese NSK bearing open when installation package, and dip it in the liquid such as gasoline to handle gently slow to turn, to ensure that maintains a, roller and groove surface the encapsulation of the oil to be cleaned thoroughly clean.
Five, many Japanese NSK bearings cleaning, use first temperature of 90 ~ 100 ℃ hot oil pour hot to make packaging oil melting, at the same time use the seamless mouth and do not fall scurf dig net all old oil tool, drizzle hot a few minutes and then rinse with kerosene to oil, and finally to use gas cleaning it again. After washing clean, should wear gloves NSK bearing Japanese film will be on the table clean cloth or paper to dry.
Six, pay attention to the Japanese NSK bearings with seal not with this law cleaning, sealed internal should remain the same shall not cleaning.
