By looking at the surface of the existence of turbid oil traces to determine the quality of spherical bearings, rust-proof technology is not very mature, so the anti-rust treatment of the external spherical bearings is very easy to leave thick oil traces, There is a sticky feeling. While the original foreign imports of bearings above basically do not see the traces of anti-rust oil, but there is a hint of taste, there must be anti-rust oil to deal with, but can not see. This method in the purchase of imported spherical bearings should be noted.
In addition, you can view the spherical bearing body above whether the brands words or labels and so on. Although the font is relatively small, but most of the products produced by the use of stamping technology, and in the absence of heat treatment will be carried out before the appropriate pressure word, although the font is relatively small, but deep depression, their very clear. The counterfeit product font is more vague, because the printing technology is rough, the font floating on the surface, and some can even easily erase by hand. View above the packaging is from the conditions of clearance of the production of packaging manufacturers, lines and color blocks are clear enough, unambiguous.
