How to identify self-aligning ball bearing of true and false

The introduction of Self-aligning ball bearing
Self-aligning ball bearing with two structures of bore cylindrical or tapered and retainers made of steel sheet or synthetic resins.The bearings are characteristic of their way into spherical shape, have so can compensate concentricity and deflection errors, but which shall not exceed 3 degrees between inner ring and outer.

Steel is the words clearly
Every product bearing on bearing products body printed with the brand, label, etc.
And usually, counterfeit products of font instead of fuzzy, because of printing technology coarse, font float to the surface, some even can easily erase traces or manually by hand.
Is there a ring
The bearing body with his left hand, right hand small reciprocating toggle coat to make it spin, listen to bearing ring if there is a noise in the process of operation.
This is to determine whether a product from the production standard strictly, and use the brand of machine operation of formal manufacturers product key.
If there is a muddy soil surface
If there is a muddy surface oil stains which need we should pay special attention to when buying imported bearings.
According to the personage inside course of study introduces, particularly careful people can smell a special kind of imported bearing, this is the flavor of the anti-rust oil.
Chamfering is uniform
So-called bearing chamfer, namely horizontal plane and vertical plane junction, fake bearing products because of the limitation of production technology in the area of the fringes is handled in guanzhou, as we can easily identify.
Bearing the packing
Finished packing part and outer bearing in the manufacturing and after inspection, cleaning and antirust processing, then put into the inner packing, in order to achieve the waterproof, moisture-proof, dustproof, shock, maintenance quality and precision of the bearing and the purpose of convenient use and sell.By mutual agreement, with easy to use for the principle, the simple packaging.
The long antirust period: rust period of two years, is applicable to special and precision bearing.
The above materials are need to ensure that material corrosion resistance test.
