Bearings are an important part of contemporary machinery. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Its accuracy, performance, longevity and reliability play a decisive role in the accuracy, performance, longevity and reliability of the mainframe.
According to the friction properties of moving components, bearings can be divided into rolling bearings and sliding bearings. Among them, the rolling bearing has been standardized and serialized, but its radial size, vibration and noise are larger than the sliding bearing, and the price is also high.
Rolling bearings generally consist of an outer ring, an inner ring, a rolling element and a cage. According to the shape of the rolling element, the rolling bearing is divided into two categories: ball bearing and roller bearing.
The needle roller bearing is equipped with a thin and long roller, so the radial structure is compact, its inner diameter size and load capacity are the same as other types of bearings, the outer diameter is the smallest, especially suitable for radial mounting size limited support structure.
Needle roller bearings can be selected from bearings without inner rings or needle roller and cage assemblies depending on the application. The journal surface and the housing hole surface that match the bearing directly serve as the inner and outer rolling surfaces of the bearing to ensure the load capacity. The running performance is the same as that of the ferrule bearing. The hardness of the shaft or shell hole raceway surface, machining accuracy and surface quality should be matched with the bearing ring.

A forging is an object to which a metal is pressed to shape a desired shape or a suitable compressive force by plastic deformation. This power is typically achieved by using a hammer or pressure. The forging process creates a refined grain structure and improves the physical properties of the metal.
The forgings have a stretchable length, a collapsible cross section. The types of forgings are: free forging / hand forging, hot forging / precision forging, upset forging, roll forging and die forging. Forgings are made of high-strength, wear-resistant, corrosion-resistant aluminum alloys, titanium alloys, nickel-based alloys and other precious materials.
Forgings have a wide range of applications in petrochemical equipment. Such as manholes and flanges of spherical storage tanks, various tube sheets required for heat exchangers, forging cylinders (pressure vessels) for butt-welding catalytic cracking reactors, barrels for hydrogenation reactors, fertilizers The top cover, bottom cover, and head required for the equipment are forgings.
Compared with other processing methods, forging processing has higher production efficiency. It eliminates internal defects in parts or blanks. Forgings have good shape and dimensional stability and high comprehensive mechanical properties. The biggest advantage of forgings is good toughness, reasonable fiber structure and small change in properties between forgings.

These hardware parts refer to the molds for steel/non-ferrous metals such as steel at room temperature, which are formed into a specified shape by the pressure required by the press. Its processing methods include cold/hot stamping, extrusion, rolling, welding, cutting and other processes.
It is beneficial to improve the utilization of metal materials, reduce the variety and specifications of materials, and minimize the consumption of materials.
These hardware parts are simple in shape and reasonable in structure, so as to simplify the structure of the mold and simplify the number of processes, that is, to complete the processing of the entire part with the least and simplest stamping process. It can facilitate stamping operations and facilitate the organization of mechanized and automated production to increase labor productivity.
It can be used alone or as an aid. It can be used as an accessory for industrial manufacturing, as a semi-finished product and as a tool for the production process.
