Introduction of self-aligning ball bearings

Self-aligning ball bearing: between the inner ring of the two raceways and the outer ring of which the raceway is spherical, the bearing is equipped with drum rollers. The center of curvature of the outer ring raceway surface is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and housing are deflected, they can be adjusted automatically without increasing the bearing burden. Spherical roller bearings can withstand radial loads and axial loads in two directions. Self-aligning ball bearings have a large radial load capacity and are suitable for heavy loads and shock loads. The inner diameter of the inner ring is a bearing with a tapered bore, which can be directly mounted. Or install it on the cylindrical shaft using an adapter sleeve and a dismantling sleeve.

Introduction of Needle Roller Bearings

Needle roller bearings are equipped with thin and long rollers (the length of the roller is 3~10 times the diameter, and the diameter is generally not more than 5mm), so the radial structure is compact, and its inner diameter and load capacity are the same as other types of bearings. The smallest diameter, especially suitable for supporting structures with limited radial installation size. Needle roller bearings can choose bearings without inner rings or needle roller and cage assemblies according to different applications. The surface of the hole is directly used as the inner and outer rolling surfaces of the bearing. In order to ensure the same load capacity and running performance as the bearing with ring, the hardness, machining accuracy and surface quality of the surface of the shaft or housing hole raceway should be the same as that of the bearing ring. Needle bearing is a bearing unit composed of radial needle roller bearing and thrust bearing components. It has a compact structure, small volume and high rotation accuracy. It can bear a certain axial load while bearing a high radial load.

How is the development of the bearing industry?

Bearings are important basic components of various mechanical equipment, and their accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the host. Among mechanical products, bearings are high-precision products, which not only require comprehensive support from mathematics, physics and many other disciplines, but also require material science, heat treatment technology, precision machining and measurement technology, numerical control technology, effective numerical methods and powerful computers. Technology and many other disciplines serve it, so the bearing is a product that represents the national scientific and technological strength.

What is a bearing?

Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.
