How to distinguish between high-speed spindle bearings and low-speed bearings

Bearings are an indispensable part of many mechanical parts. The functional application of bearings will affect the performance of spindle equipment. Therefore, many people will also care about the performance of bearings when purchasing spindle equipment. Among them, the high and low speed of bearings The operation of the bearing application plays a decisive role, so this article will answer you how to distinguish between high-speed spindle bearings and low-speed spindle bearings. Many good friends may misunderstand him. It is not that the rotational speed of the bearing itself is unusual, but that the internal structure of the bearing is different to a certain extent. The bearing belongs to the fast or low gear and is distinguished by its angular velocity. The speed of many low-speed bearings in min can also reach tens of thousands of revolutions, but there are some high-speed spindle bearings, which are only a few hundred revolutions per minute. In addition to their naming and their angular velocity, there is another difference that the parts used for rotation in their structures are not the same. Generally speaking, the rotating part of the low-speed bearing is elliptical. Some are cylindrical or even conical, and the rotating part of the high-speed spindle bearing is mainly the bearing pad. There are also some differences between the two types of bearings. Generally speaking, the low-speed bearing has a less smooth surface, and the junction between parts and parts should be looser. In order to ensure the accuracy of high-speed spindle bearings and other high-precision levels, the surface will generally be very smooth, and at the same time, the distance between the inner hole and the outer side is not large, and the accuracy level of others will be much higher. Another point is that on the material, there is also a slight difference between high-speed and slow-speed bearings. High-speed spindle bearings are generally made of very high-toughness stainless steel plates, which can withstand the working pressure generated by the parts caused by excessive rotation speed. If the speed of the general bearing is relatively low, the application is basically some ordinary materials, and it does not need to bear a lot of working pressure, so the requirements for the strength of the material and the durability of the material are correspondingly reduced. Whether it is a low-speed gear or a high-speed spindle bearing, all of them are actually produced after repeated design and continuous testing. Although its parts are very small, their technological innovations and changes can usually promote the development trend of an industry chain, and the effect may not be underestimated. The torque is accurate, in order to turn stable!
