How to identify bearing

    Identify the quality of the equipment bearing, we usually carry out the following aspects:
    The packaging is clear double row tapered roller bearings under normal circumstances, the regular manufacturers brand has its own dedicated external packaging designers to design and make arrangements for the clearance of the factory production conditions for production,therefore, in terms of product packaging lines the color should be very clear and unambiguous.
    Seal word is clear or not
    Bearing products every body will be in products thin section bearing the words printed on its brand, label and so on. Although the font is very small, but regular manufacturers of products using the stamp printing technology, but without the heat-treatment is carried out embossing, so the font may be small, but a deep concave, very clear. And under normal circumstances, not only fuzzy fonts counterfeit products, due to the rough printing technology, fonts floating on the surface, some of them can be easily erased or manually by hand signs seriously.
    Are there hetero ring
    Left hand holding the bearing sleeve body, right hand toggle coat a small margin to rotate back and forth, listening to the bearings during operation if there hetero ring. Because the majority of counterfeit products production conditions behind, completely hand-workshop-type operation, slim ball bearing the body in the production process will inevitably be braced with dust, sand a class of impurities, so in the bearing is rotating when there will be a hybrid ring or the phenomenon does not run smoothly . This is to determine whether the product by strict production standards, and the key with the regular operation of the
machine manufacturer's brand products.
     Are there traces of oil muddy surface
     Are there traces of oil muddy surface which requires that we should pay special attention to when buying imported bearings. It is easy to leave a thick oil stains Because there is a certain gap between domestic and foreign anti-rust technology advanced manufacturing country, therefore bearing body rust treatment, feeling sticky sticky thick hand contact when, while foreign original on imported bearings hardly see any trace of rust preventive oils. According to insiders, particularly careful person can smell the bearings to a special flavor, which is anti-rust oil taste.
     Chamfer is uniform
     The so-called bearing chamfer, which is the junction of the horizontal surface and vertical surface, counterfeit products slewing ring bearing

 production technology due to restrictions in parts of these corners was unsatisfactory treatment, which we can easily identify.
Bearing Package Packaging fair share in the manufacturing of packaging and packaging bearing completed and passed the test, namely cleaning and anti-rust treatment, then put the package in order to achieve water, moisture, dust, shock, maintaining quality and precision bearings and the purpose of ease of use and sale.
