Three ways to identify the quality of backing bearings:

1. whether the outer packaging is clear In general
Generally, the backing bearings produced by regular manufacturers have their own special designers to design the external packaging, and arrange factories with qualified production conditions for production. Therefore, the product packaging should be very clear from line to color block without paste.

2. Whether the steel seal is clear
Each backing bearing product will be printed with its brand words, label, etc. on the backing bearing product body. Although the font is very small, the products produced by regular manufacturers use steel printing technology, and press the font before overheating treatment. Therefore, although the font is small, it is deeply concave and very clear. In general, the font of counterfeit products is not only fuzzy, but also floating on the surface due to the rough printing technology. Some of them can even be easily erased by hand or the manual marks are serious.

3. Is there any noise
Hold the inner sleeve of the backing bearing with your left hand and rotate the outer sleeve with your right hand to listen to whether there is any noise during the operation of the bearing. Due to the backward production conditions of most counterfeit products and complete manual workshop operation, impurities such as dust and sand will inevitably be mixed in the bearing during the production process, so there will be noise or poor operation when the bearing rotates. This is the key to judge whether the products come from the brand products of regular manufacturers with strict production standards and machine operation.
