A brief history of bearing development

The first condition for friction is that two objects are in contact. There are two types of contact, one is face-to-face contact and the other is point-to-point contact. The first method is like picking up a hand; there is a lot of frictional resistance and a lot of heat is generated. This method is called sliding friction. The second method is like a ball rolling on the ground with low frictional resistance and fast rolling speed. This method is called rolling friction. Secondly, the material of the contact surface and the weight of the moving object also have an effect on frictional resistance, which we will discuss later.

Rapid growth in the construction machinery industry will continue to grow in 2019

Due to a low operating base in 2016, growth rates were very high in both 2017 and 2018.Total industry-wide equipment production grew by 45. 7 per cent in 2017 and 27.2 per cent from January - November 2018.The industry's operating income grew by 12 per cent year-on-year from January to November 2018, exceeding the target of 20 per cent year-on-year growth in 2018, and reaching an all-time high.The industry's operating income grew by 12 per cent year-on-year from January to November 2018, exceeding the target of 20 per cent year-on-year growth in 2018, and reaching an all-time high. Products with large increases were mainly in the two categories of excavators and cranes.

Bearing industry development trend

Data show that more than 70% of the global bearing market share is shared by eight multinational bearing group companies, including Sweden SKF (SKF), Germany Schaeffler Group's INA and FAG, Japan's NSK (NSK), NTN, KOYO, Minebea, Nachi and at the same time, the world's bearings in the industry's high-end market is monopolised by the above enterprises, and the low-end market is mainly The middle and low-end market is mainly concentrated in China.
