How to Identify the Quality of Ball Bearings?

Aug 26, 2021

Ball bearings have different characteristics according to category and design, which makes each category of ball bearings different in characteristics. For example, deep groove ball bearings can accept moderate radial and axial loads. They have low friction, high accuracy, and meet the requirements of quiet operation. They are more suitable for small and medium-sized electric motors. Spherical and roller bearings can accept very high loads. Such characteristics make them very suitable for use in, for example, heavy engineering, which may have heavy loads, shaft deflection, and misalignment.

To distinguish the quality of ball bearings, we usually from the following aspects:


1. The packaging is clear. Under normal circumstances, the brand of the right-track manufacturer has dedicated designers to design the external packaging. The packaging of the product should be very clear and unambiguous from the line to the color.


2. Clear typing: each bearing product will have its brand name, label, etc. printed on the bearing. Under normal circumstances, the fonts of low-quality products are vague. Due to the rough printing technology, the fonts float on the outside, and some can even be erased by hand.


3. Whether there is noise: hold the inner ring of the ball bearing with your left hand, and turn the outer ring with your right hand to make it rotate, and listen to whether there is noise during the operation of the bearing. As most of the counterfeit products are under backward consumption conditions and complete manual workshop operation, it is inevitable that the bearings will be mixed with impurities such as dust and sand during the production process. Therefore, when the bearings are rotating, there will be noise or unsmooth operation. .


4. Whether there are oil stains on the surface: Whether there are turbid oil stains on the surface, we should pay special attention to it when purchasing bearings. Because the current domestic anti-rust technology still has a certain gap with foreign advanced manufacturing countries, it is easy to leave thick oil stains when the bearing body is rust-proofed. There is almost no trace of anti-rust oil on the quality bearing.


5. Chamfering: The chamfering of the bearing, that is, the junction of the horizontal plane and the vertical plane. Due to the limitation of production technology, the counterfeit bearing products have not been properly handled at these corners. We can easily see this.

These are just simple methods to judge the quality of the bearing. If you want to buy high-quality bearings, you need to have a deeper understanding of the bearings and buy them through formal channels. If you need all kinds of ball bearings, please contact us, sales@fv-bearing.com.
