Method for distinguishing the authenticity of heavy caster bearing
1: Scale weight: for "NSK" heavy bearings of the same model, the materials of fake heavy bearings

are significantly less than those of genuine ones. Because most fake heavy bearings cut corners

and replace high oxidation special steel with general steel, it will be lighter than genuine products

in weight.

2: Look at the packaging: the fake "NSK" brand heavy bearing outer packaging is slightly different

from the genuine "NSK" brand heavy bearing outer packaging. The "NSK" trademark marked on the

right side of the packaging box is in red and bold, while the genuine "NSK" trademark is in white and

bold. From the appearance of heavy bearings, SKF SKF imported heavy bearings are generally

packed in cartons. The color of cartons is dark blue, and the heavy bearing model printed on it is

very clear that NSK anti-counterfeiting technology is used. The fake heavy-duty bearing is difficult

to do this. The color of the box is relatively light and easy to fade. The font of heavy bearing model

is also in a trance

3: Whether there is any noise: hold the heavy bearing body sleeve with your left hand, and turn the

sleeve with your right hand to listen for any noise. Because the production premise of most counterfeit

products is backward, impurities will inevitably be mixed in the production process and hidden in the

heavy bearing body, so it will make a noise when rotating. This is the biggest difference between the

factory brand that strictly implements the production standards and is operated by machines.

4: Whether the chamfering is average: the chamfering of the so-called heavy-duty bearing, that is,

the junction of the horizontal and vertical surfaces. Due to the limitation of production technology, the

fake heavy-duty bearing is not handled satisfactorily in these corners.
