How to distinguish the performance and quality of 36 kinds of self-aligning roller bearings

To identify the quality of 36 kinds of self-aligning roller bearings, we usually carry out the following aspects

Whether the outer packaging is clear? Generally, the brands produced by regular manufacturers have their own special designers to design the outer packaging, and arrange the factories with qualified production conditions for production. Therefore, the packaging of products, from lines to color blocks, should be very clear and unambiguous.

Whether the steel seal is clear

Each type 36 self-aligning roller bearing product will be printed with its brand words and label on the product body of type 36 self-aligning roller bearing. 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.

Is there any noise

Hold the inner sleeve of type 36 self-aligning roller bearing with your left hand, and move the outer sleeve back and forth with your right hand to make it rotate. Listen to whether there is any noise during the operation of type 36 self-aligning roller bearing. Due to the backward production conditions of most counterfeit products and the complete manual workshop operation, it is inevitable that impurities such as dust and sand will be mixed into the body of class 36 self-aligning roller bearing in the production process, so there will be noise or unsmooth operation when class 36 self-aligning roller 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.
