How to distinguish the quality of the bearing?

To identify the quality of equipment bearings, we usually proceed from the following aspects:

1. Is the packaging clear?

Under normal circumstances, brands produced by regular manufacturers have their own dedicated designers to design external packaging, and arrange factories that pass the production conditions for production. Therefore, the packaging of the product should be very clear from lines to color blocks. unambiguous.

2.Is the steel printing clear?

Each bearing product is printed with its brand name, label, etc. on the bearing product body. Although the font is very small, the products produced by regular manufacturers use steel stamping technology and embossing before heat treatment. Therefore, although the font is small, it is deep and very clear. Under normal circumstances, the fonts of counterfeit products are not only vague. Because of the rough printing technology, the fonts float on the surface, and some can be easily erased by hand or the marks are severe.

3. Whether there is noise

Hold the inner sleeve of the bearing with your left hand, and turn the outer sleeve to rotate with your right hand. Listen for any noise during the running of the bearing. Due to the backward production conditions of most counterfeit products and completely manual workshop operation, impurities such as dust and sand will inevitably be mixed into the bearing body during the production process, so when the bearing rotates, noise or unsmooth operation will occur. . This is the key to judging whether the product comes from a branded product of a regular manufacturer with strict production standards and machine operation.

4.Is there any turbid oil on the surface?

Whether there is turbid oil on the surface This requires us to pay special attention when purchasing imported bearings. Because the current domestic rust prevention technology still has a certain gap with foreign advanced manufacturing countries, it is easy to leave thick oil marks when rust-proofing the bearing body, and it feels sticky and thick when contacted by hand. Hardly any trace of anti-rust oil can be seen on the imported bearings. According to industry insiders, particularly careful people can smell a special taste on imported bearings, which is the smell of anti-rust oil.

5.Is the chamfer even?

The so-called chamfer of the bearing, that is, the intersection of the horizontal and vertical surfaces, due to the limitation of production technology, counterfeit bearing products are not handled satisfactorily at these corners, which can be easily identified.
