How to distinguish the advantages and disadvantages of bearings

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 production in factories that pass the production conditions. 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 deeply concave 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. Some of them 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, and listen for any noise during the running of the bearing. Due to the backward production conditions of most counterfeit products and complete 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 there is still a certain gap between the current domestic rust prevention technology and advanced foreign manufacturing countries, it is easy to leave a thick oil mark when the bearing body is subjected to rust prevention treatment. Hardly any trace of anti-rust oil can be seen on the imported bearings. According to industry insiders, particularly attentive 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.
