Many procurement personnel are purchasingSynchronous electric spindleWhen it comes to bearings, it is often difficult to distinguish between good and bad, and the quality of synchronous electric spindle bearings determines whether the electric spindle can operate normally. So what are some good methods to identify the advantages and disadvantages of electric spindle bearings?

The advantages and disadvantages of synchronous electric spindle bearings can be identified from the following four aspects:

1. Steel stamp. Steel stamp is an important factor in identifying the authenticity of bearings. Before the bearings undergo overheating treatment, professional steel stamp technology is used to press the characters on the stamp, so the font is clear. The bearing body is usually printed with various manufacturer information such as words and brands, and the steel seal is an important factor in identifying the authenticity of the bearing.

2. Oil stains. Some manufacturers add thick oil stains on the surface of bearings to achieve rust prevention, reducing their own smoothness. The oil stains on the surface of the bearing body determine the rust prevention ability of the bearing product.

3. Color. The appearance color of bearings can fully reflect the material condition of bearing products. Some manufacturers have put a lot of effort into the use of steel, reducing the number of steel types and replacing them with rough and shoddy steel. The appearance color is mostly white, which is significantly different from the green color of bearing steel. However, the color of bearings can effectively identify these low-priced materials.

4. Outer packaging. Large brand bearing manufacturers also put effort into the design of product appearance, because they focus on brand image and market influence, and both the modules and lines will be clear and bright. But small manufacturers will cut corners on the packaging of their products, resulting in a blurry appearance.

Professional procurement personnel must know where the bearings of synchronous electric spindles come from. Imported bearings have relevant qualification certificates, and domestically purchased original imported bearings also have customs declaration forms and certificates of origin. These are the issues you need to pay attention to when choosing electric spindle bearings. Only by knowing clearly can you avoid being deceived to the greatest extent.
