1. Look at the bearing appearance; bearing finish; below (â–³8) is a fake; the authentic type is not afraid of rubbing with a laser; the fake type is wiped off.
2. The corners of the bearing are black; the real product is not afraid of water and does not fade. The fake product sees the water into black mud; perhaps it is wiped off; perhaps the black paint is directly used.
3. Most of the bearing packaging is done in the same way. The demand is verified by experience.
Whether the outer packaging can be clearly defined; the factory brand has a special depiction of the external packaging; and the factory that produces the production conditions is manufactured; therefore, the packaging is clear from line to color; unambiguous Some imported brands also have a common depiction on the packaging of their own intellectual property.
Whether the steel printing can be clearly printed on the bearing body will be printed with the brand name, label, etc. The font is very.

Can you have a left-handed grip on the inner sleeve of the bearing; use your right hand to turn the outer sleeve to make it rotate; listen to its noise, because the production conditions of most counterfeit products are backward; thoroughly craft workshop operation; inevitably in the production process Incorporating impurities such as sand; hiding in the bearing body; so the noise will be announced during the rotation. This is the biggest difference between the strict implementation of the production specifications and the operation of the factory brand.
Whether the appearance of dirty oil traces should be uniquely noted when purchasing imported bearings. Because the current domestic anti-rust skills are not unique to the home; therefore, it is very simple to leave a thick oil trace when the bearing body is rust-proofed; Sticky and sticky on the hand; foreign imported bearings can not see the traces of anti-rust oil; but it is a unique and careful expert said that the imported bearings smell a smell; definitely the anti-rust oil; just look Not enough.
Whether the chamfer can evenly mean the chamfer of the bearing; that is, the intersection of the horizontal and the vertical; the counterfeit bearing is restrained by the production skill; the position of the corners is not satisfactory.
