How To Distinguish Spherical Roller Bearings?

wallpapers Robot Tech 2021-01-15
Spherical roller bearings are bearings with drum-shaped rollers assembled between the inner ring with two raceways and the outer ring with spherical raceways.
 
To identify the quality of equipment bearings, we usually proceed from the following aspects
 
Is the outer packaging clear?
Double-row tapered roller bearings. Under normal circumstances, the brands produced by regular manufacturers have their own dedicated designers to design the external packaging, and arrange for the production of factories that pass the production conditions. Therefore, the packaging of the products is from lines to color blocks. It should be very clear and unambiguous.
 
Is the steel stamp clear
Each bearing product will have its brand name, label, etc. printed on the bearing product body. Although the fonts are very small, the products produced by regular manufacturers are printed with steel stamping technology, and the fonts are pressed before heat treatment. Therefore, although the fonts are small, they are deeply concave and very clear. Normally, the fonts of counterfeit products are not only blurred. Due to the rough printing technology, the fonts float on the surface, and some can even be easily erased by hand or have serious manual traces.

 
Whether there is noise
Hold the inner sleeve of the bearing with your left hand, and turn the outer sleeve with your right hand to make it rotate. Listen for noise during the operation of the bearing. Due to the backward production conditions of most counterfeit products, it is completely manual workshop operation. During the production process, the bearing body will inevitably be mixed with impurities such as dust and sand. Therefore, noise or unsmooth operation will occur when the bearing rotates. . This is the key to judging whether the product comes from a regular manufacturer's brand product that has strict production standards and is operated by machines.
 
Whether there are turbid oil stains on the surface
Whether there are turbid oil stains on the surface, this requires us to pay special attention when buying imported bearings. Because there is still a certain gap between the domestic anti-rust technology and foreign advanced manufacturing countries, it is easy to leave thick oil stains when the bearing body is anti-rust treatment, and it feels sticky and sticky when touched by hand, while foreign original There is almost no trace of anti-rust oil on the imported bearings. According to industry insiders, particularly careful people can smell a special smell on imported bearings, which is the smell of anti-rust oil.
 
Is the chamfer uniform
The so-called chamfer of the bearing is the junction of the horizontal plane and the vertical plane. Due to the limitation of production technology, the counterfeit bearing products are not handled satisfactorily at these corners and corners. We can easily distinguish this.
