Technical conditions for NSK bearing inventory

    It is not diesel that does not prevent rust. It is too much water content for diesel. In addition, NSK bearings must not be cleaned with chemicals with strong acid and alkali. NSK bearing steel is more likely to rust than ordinary carbon steel.
    If the NSK bearing is wetted by water, it needs to be cleaned with gasoline or kerosene, dried after washing, and then coated with a lower viscosity oil or special anti-rust oil on the NSK bearing. The anti-rust oil is applied to the NSK bearing. The surface will form a layer of oil film. The oil film will block the air from contacting with the NSK bearing and also prevent moisture. After evenly applying the anti-rust oil, the NSK bearing should be wrapped with a thick plastic film. The package must be tightly attached to the NSK bearing. Not breathable. A thicker layer of kraft paper should be wrapped outside the plastic film to prevent moisture and prevent the plastic film from being damaged after collision. If there is no kraft paper, it can be replaced by other paper materials. NSK bearings should be contacted with acid or alkaline substances. Perform the above maintenance steps in a timely manner.
    When NSK bearings need long-distance transportation, they must be packaged according to the above requirements, and then packed into cartons for packaging and transportation. It is necessary to ensure the firmness and sealing of NSK bearing outer packaging. It is best to add a layer of seal to the packaging box. The packaging material used, such as snakeskin bags, can prevent the NSK bearing from being damaged after the carton is damaged and rained during handling.

The main difference between SKF bearings and domestic bearings

1, the difference between the models
    With the advent of the international tide, the domestic bearing code is gradually integrated with the SKF bearing code. The latest published national standards show that the domestic code is basically the same as the international ISO standard.
    The mark on the bearing, such as the famous bearing of the domestic bearing, is that the Luoyang axis code is (LUO) and the Harbin bearing code is (HA) basically the same. Each bearing has a digital code indicating that the bearing type has a pinyin mark to represent the place of origin. If you want to be a person from the mechanical industry, you should know.
2, other aspects
    Compared with domestic bearings, SKF bearings are generally better in materials than domestic ones. The heat treatment process is more advanced than domestic ones, with high manufacturing precision, more reasonable manufacturing and assembly processes, and long service life. Of course, the price is higher. And SKF bearings are generally more genuine, the most important thing is that SKF bearings are made in foreign countries. Haha, this is not to say that everyone can understand.
    For the life, although the service life of SKF bearings is longer than that of domestic ones, if the ordinary machines are not very high in terms of precision, they can be made domestically. Now the quality of bearings produced by major manufacturers such as HRB and ZWZ is very good. Good. The price is also suitable, can also be used to live. But when the accuracy is required, it is still a good point of SKF.
