Bearing manufacturer teach you bearing the authenticity of five tips

Bearing manufacturer teach you bearing the authenticity of sources of five tips: bearing | last updated: - 2020 06 - 23 bearing manufacturer teach you bearing the authenticity of five tip bearing the authenticity of five small tip 1. Bearing outer packing is clear: under normal circumstances, the original brand has its own professional designers design the packaging, and have the production conditions of the plant through the production schedule, so the packaging from the piece of the line, no doubt about it. 2. Seal is clear: the bearing will be printed with the brand name and label. Font is very small, but most of the products factory all use steel stamping technology, and suppress before heat treatment. So, although the font is very small, but it is a deep concave and very clear. Counterfeit products font is not only vague, but due to the rough printing technology, font floating on the surface, some even can be easily erased by hand. 3. If there is a noise: holding sleeve bearing subject with his left hand, and then turn the coat with the right hand rotation, listen to whether there is a noise. Because most of the counterfeit products production conditions, complete workshop by artificial operation, will inevitably in the process of production with the impurities such as sand and hid in the bearing, so the noises when rotating. With the strict production standards and on the machine running the biggest difference between the real factory brand. 4. Surface whether there is oil pollution: buy bearing should pay special attention to. Because of the current domestic antirust technology is not particularly popular, so after the antirust processing, it is easy to leave thicker oil stains on the bearing body, and feel very sticky, bearings imported from abroad are hardly found traces of anti-rust oil, but careful, experts say, bearing smells a bit smelly. It must be under the anti-rust oil, but it is not visible. 5. Chamfering whether uniform: bearing the so-called chamfering, namely horizontal surface and the vertical surface intersection, due to the limitation of production technology, counterfeit bearings on the Angle of process well. Bearing the radial direction of the straight line 1 is along the diameter or radius, radial straight direction is along the diameter or radius and or perpendicular to the axis line direction. On the surface, usually refers to a point as the center of the tangent plane, by which the direction of the straight line. In the radio navigation or radio measurement, especially through a central point ( Line) Extending direction of magnetic field lines. 2, object of axial is usually based on cylinder, is the direction of the cylinder center of rotation axis, with central axis in the same direction. 'Radial' perpendicular to 'axis', namely the end of the radius of the circle or cylinder diameter direction. The radial and axial vertical space. Analysis object in the physical force or motion is also using this concept.
