Identify the quality of equipment bearings, aligning bearings, we usually from the following aspects of packaging is clear double row tapered roller bearings Under normal circumstances, self-aligning bearing manufacturers of regular manufacturers have their own brand of special design packaging design , And arrange production conditions for the production of factory production, therefore, the product of the packaging in terms of lines to the color block should be very clear and unambiguous.
Steel printing is clear
Each bearing products will be bearing the product body printed on its brand words, labels and so on. Although the font is very small, but the regular manufacturers of products using a stamp technology printing, but also in the heat treatment before the word is not, so the font is small, but concave deep, very clear. And usually, counterfeit products, not only the font is fuzzy, because the printing technology is rough, the font floating on the surface, and some even easily can be erased by hand or hand marks.
Whether there is noise
Left hand holding the bearing body sleeve, right hand small amplitude of the back and forth toggle jacket to rotate, listening to the bearing running process whether there is noise. As most of the counterfeit products, production conditions are backward, completely hand-workshop operation, self-aligning bearing in the production process will inevitably be incorporated into the body of dust, sand and other impurities, so when the bearing rotation will appear noise or noise Smooth phenomenon. This is the key to judging whether a product comes from a branded product of a regular manufacturer with strict production standards and machine operation.
Whether the surface of turbid oil traces
The surface is turbid oil traces that we need to buy imported bearings should pay special attention. As the domestic anti-rust technology and foreign advanced manufacturing countries there is a certain gap, so the bearing body rust treatment is easy to leave a thick traces of oil, feel thick sticky sticky, and foreign original Imported bearings almost do not see any trace of anti-rust oil. According to industry insiders, self-aligning bearings can be particularly careful people in the imported bearings to smell a special taste, this is the taste of rust-proof oil.
Whether the chamfer is even
The so-called bearing chamfer, which is the junction of the horizontal and vertical surface, counterfeit bearing products due to production technology constraints, in these parts of the edges and corners of the deal was unsatisfactory, which we can easily identify.
Bearing packaging
Packing Inner packing and outer packing After the manufacture is finished and tested, the self-aligning bearing is cleaned and rust-proofed, then put into the inner packing to achieve waterproof, damp proof, dustproof, shockproof and maintenance bearing. Quality and accuracy, as well as ease of use and marketing purposes.
