Bearings are a very important component in a machine and equipment, so the requirements for them are very demanding. Once there is a problem, the economic cost paid is not to mention, the machine failure is still small, and the serious will lead to production and safety accidents, and the consequences are unimaginable. Today we will make an introduction to the true and false identification of the "NSK" bearing.
The outer packaging of counterfeit "NSK" brand bearings is slightly different from the outer packaging of genuine "NSK" brand bearings, and the "NSK" trademark marked on the right side of the box is red and bold, while the genuine "NSK" trademark is white and black. From the bearing appearance, NSK bearings are generally packed in cartons, and the color of the carton is dark blue, and the bearing number printed on it is very clear, using NSK anti-counterfeiting technology.
False bearings are difficult to do, and the box color is relatively light and it is easy to fade. The bearing designation font is also relatively blurry. After the bearing is used, it should be checked whether the rolling elements and inner ring raceways are peeled, whether the cage is too loose, whether the front and rear edges of the inner ring are intact, and whether there are cracks in the outer ring raceways. After the inner ring and roller combination are loaded into the outer ring, the roller should fall into the middle of the raceway with a forward movement of no more than 1.5mm. One of them is unqualified, that is, it cannot be used. The price of NSK bearings is of course much higher than the price of domestic bearings, and what you want to buy NSK bearings at the price of domestic bearings must be fake.
Through a specific analysis of the market by the general distribution of bearings and the identification of the authenticity of NSK bearings, it can help more customer groups to buy genuine products of NSK bearings, so that more customers have more awareness and awareness of NSK bearings, and hope that this knowledge can play a greater role for you.
Nowadays, there are many imported bearing brands on the market, bearing models are available, and there are countless dealers, but it is not an easy task to buy assured imported bearing products from the market. If you are not careful, you will fall into the trap of the dealer, so Tianjin Avrin hereby reminds customers to be careful, and the following briefly introduces our experience.
How to distinguish genuine and fake imported bearings
1. Look at the appearance of the bearing, the bearing finish, lower than (△8) is a fake, the genuine model is engraved with a laser is not afraid of wiping, the fake model will be wiped off.
2. The corners of the bearing are black, and the genuine product is not afraid of water and does not fade. Fakes see water into black mud, or wipe it off, or directly use black paint.
3. Most of the bearing packaging is done the same as the real thing. Empirical verification is required.
Counterfeit bearings
1. The appearance is the same as the real thing, but it is not known whether the bearing capacity and limiting speed are suitable for the purpose
2. In order to reduce manufacturing costs, there are no requirements for precision
3. In order to reduce the price, use low-quality bearing steel materials
4. The packaging and transportation processing methods are not standardized, which adversely affects the accuracy of bearing products
