Misunderstandings in Judging the Quality of Rolling Bearings

As a professional manufacturer of rolling mill bearings, Luoyang FV often receives some questions from customers about bearing quality. For example, the chamfer of the bearing I purchased is black, is the material of the bearing bad? Or is there a problem in the processing link and so on. There are many similar problems. Today we will talk about three problems. These are the most common misunderstandings that consumers fall into. I hope it can help you.

1. Judging the quality of the rolling bearing only by the surface of the bearing

When we get a bearing, the first thing we see is the appearance of the bearing. The appearance of the rolling mill bearing is a criterion for judging the quality of the bearing, but it is not the only criterion. The world-class brand bearings, such as SKF, TIMKEN bearings, are indeed very beautiful, clean, and they look great in quality. Some customers buy bearings from other brands and find that the bearing surface is black and not bright, and they will suspect that my bearing is bad. The appearance of the bearing is different depending on whether the steel used is of high quality, as well as all aspects of the production process. Bearings of the same type are used in this occasion such as the load is not large, they use of ordinary materials can meet the needs of customers and reduce costs for customers. However, in another occasion, another kind of bearing material may be required to meet high load requirements, etc.

2. Judging the quality of the roll neck bearing by the brightness of the chamfer

The chamfer of a good bearing must be perfect, just like a handicraft. But at the same time, we also look at the material and hardness of the bearing. Some manufacturers produce high imitation bearings, the chamfers are also very beautiful, but the hardness and other aspects are not good, such bearings are not useful. The chamfer of some bearings is black, although it is not bright, it means that the bearing has undergone heat treatment such as quenching, which increases the hardness of the bearing, and such a bearing is more durable.

3. Judging only by the cage

For the same type of bearing, some manufacturers use a one-piece cage design, and some use a two-body cage. Customers will wonder, in the end which kind of cage is good? The one-piece retainer saves material, which is good for the manufacturer, but good for the user or not depending on your application and usage requirements. If it meets your requirements, that's fine.
