There are many types of bearing materials, among which stainless steel is probably one of the most commonly used bearing materials. Compared with ordinary bearing steel (Chrome steel GCr15/100 Cr6/SUJ2), stainless steel bearing not only have obvious advantages in material, but also much strict in process and precision control than ordinary bearing. It is more stable, has low noise and stronger anti-rust and anti-corrosion properties, it can be us...

Full ceramic bearings have the characteristics of magnetoelectric insulation, wear resistance, corrosion resistance, oil-free self-lubrication, high temperature and cold resistance, which can be used in extremely harsh environment and special working conditions. Material ZrO2 has perfect properties such like suitable for low and high temperatures, high load capacity, corrosion resistance, nonmagnetic insultated and self-lubrication. Thus it suits...

With the development of mechanical manufacturing industry towards high precision and high speed, the application range of bearings is more and more wide, and the performance requirements of bearings are also higher and higher, especially in some special working environment, metal bearings can not adapt to the demand, or even can not work at all. Because of its low density, high modulus of elasticity, low coefficient of linear expansion, wear resi...

Bearing is an important part of mechanical rotation, and its stiffness and working temperature will directly affect the bearing efficiency on the mechanical operation. In order to provide the rotation accuracy of the bearing, increase the rigidity of the bearing device, and reduce the vibration of the shaft when the machine is working, the preloaded rolling bearing is often used, such as the spindle bearing of machine tool. The bearing stiffness ...

Powder metallurgy (PM) is a technology that uses metal powder or nonmetal powder or its mixture as raw materials to manufacture metal materials, composite materials and various types of products through forming and sintering. Its three core elements are technology, materials and equipment, which are widely used in transportation, machinery, electronics, aerospace and other important industrial fields. It is the most potential and dynamic branch o...

Sealing devices can generally be divided into static seals (fixed seals) and dynamic seals (rotating seals). The former is called gasket seal, and the latter is called gasket seal....

Sealing is indispensable for bearings. Sealing can not only prevent the leakage of lubricant, but also prevent the invasion of harmful foreign bodies. Otherwise, it will cause the abrasive wear of the bearing raceway, reduce the service life of the bearing, and make the bearing parts corroded by harmful gas and moisture, and accelerate the aging of the lubricant. ...

TBB can provide various types of maintenance-free spherical plain bearings....

“Maintenance-free” is an industry-wide term used to describe plain bearings and rod ends with self-lubricating sliding contact surface combinations. These so-called maintenance-free bearings and rod ends offer a number of advantages for OEMs and end users alike. These advantages, which include minimal maintenance and reduced lubricant consumption, quickly compensate for the difference in the initial purchase price. And of course, the impact ...

Failure Analysis of Needle Roller Bearing in Moto Crankshaft
Technical Information / 2019-06-17

Crankshaft, an essencial mechnical part, plays a great role in engine of motorcycle.Motorcycle crankshaft is made of several seperate pieces, today we only focus on the failure analysis of needle roller bearings used in crankshaft. Cause of crankshaft damage Generally it is because the oil’s not replaced in time. There are bearings in crankshafts. The bearing will wear seriously without oil or with poor lubrictaion, a gap may occur, t...

Causes & Analysis of Motorcycle Bearing Early Damage
Bearing knowledge / 2019-06-10

There are many bearings used in various active parts of a motorcycle (such as the direction column, the front and rear wheels, the rear chain plate, the rear gearbox, etc.). Bearings produced by regular manufacturers are generally tested as qualified products at the factory, but it is also important to install them correctly. During the usage of motorcycle, if the bearing ball cage falls off, the working surface in the rolling groove wi...
