YOCH Bearing

When the bearing rotates at a high speed and bears a large axial load, the end surface of the nut in contact with the inner ring of the bearing should be perpendicular to the rotation center line of the shaft. Otherwise, even if the nut is tightened, the installation position of the bearing and the normal working condition of the bearing will be destroyed, and the rotation accuracy and service life of the bearing will be reduced. Especially when the fit between the bearing inner hole and the shaft is a loose fit, strict control is needed.

The service life and reliability of rolling bearings are closely related to the metallurgical quality of the bearing steel. Due to the characteristics of bearing steel, the requirements for metallurgical quality are much stricter than those of general industrial steel.

According to the size of the load If the load or impact is large, choose roller bearings (line contact); If the load is small or the impact is small, ball bearings (point contact) should be selected.

The installation of angular contact ball bearings is more complicated than that of deep groove ball bearings. They are mostly installed in pairs and require preloading. Proper installation can greatly improve the working accuracy and bearing life of the host; otherwise, not only the accuracy will not meet the requirements, but the lifespan will also be affected.

As one of the very important mechanical parts, the bearing end cover is the main external part of the bearing seat and has a wide range of uses. The main working surfaces of this part are the left and right end faces and the cylindrical surface of the left end face. Its general functions are: (1) Axial positioning of the bearing outer ring; (2) Dust-proof and sealed. In addition to being dust-proof and sealed by itself, it is often combined with seals to achieve the sealing effect; (3) The end cover located between the lathe motor and the spindle box mainly plays the role of transmitting torque and buffering and absorbing shock, so that the spindle box rotates smoothly.

Bearing alloys, bronze, aluminum-based alloys, zinc-based alloys, etc. are all called metal materials. Among them, bearing alloy, also known as white alloy, is mainly an alloy of lead, tin, antimony or other metals. It can have low strength under heavy load, high speed and other conditions. The reason is because of its characteristics, including good wear resistance, high plasticity, good running-in performance, good thermal conductivity, good glue resistance and good oil adsorption. However, because it is more expensive, when used, it must be poured on the bearing bush of bronze, steel strip or cast iron to form a thin coating.

Pillow block flange bearing products are vital components in the industrial equipment and components industry, specifically in the field of bearings. In this article, we will explore the features, applications, and advantages of these bearings, providing you with valuable, practical knowledge. Let's dive in!

Powder metallurgy is a processing method that prepares metal powder and makes products from metal powder or a mixture of metal powder and non-metal powder through processes such as shaping and sintering. It can not only prepare special materials that are difficult to prepare by ordinary smelting methods, but also manufacture various products. A kind of precision mechanical parts, saving labor and materials. However, the cost of molds and metal powder is high, and it should not be used when the batch size is small or the size of the product is too large. Compared with traditional material processes, powder metallurgy materials and processes have the following characteristics:
