International bearing industry is fiercely competitive with domestic bearing pressure

The international bearing industry has undergone fierce market competition, survival of the fittest, and mergers and reorganizations. Ten years ago, eight leading transnational corporations had formed a dominant position, with a market share of over 80%.

In the past ten years, after further mergers and reorganizations, the eight transnational corporations consolidated the industrial layout.

Recently, Europe and the United States have introspected that “de-industrialization” has caused economic imbalances to be an important cause of the financial crisis. The “re-industrialization” in the post-crisis era is imperative. Manufacturing industries, including bearing industries, have been hit by the financial crisis. But they all have great development after recovery. China's bearing industry will be in the external environment of this international bearing industry structure for a long time, and it will be subject to tremendous competitive pressure.

Cut Anchor

Functionally, there is no difference between a cut thread and a rolled thread. The difference enters in the manufacture of the bolt. Using 1" anchor bolts as an example the processes are:

Cut thread is created by a process that cuts away the steel from the round bar to form the threads. To cut thread, the process begins with a full 1" diameter round bar. The threads are cut into the round bar resulting in an anchor bolt with 1" diameter threads and a body of 1" diameter.

Rolled thread is created by a process that extrudes steel from the surface of the round bar to form the threads. To roll thread, the process begins with .912" round bar. The round bar is rolled through a set of dies that displace the steel to form the threads. The result is a bolt with 1" diameter thread and a .912" body.

Cut thread meets all ASTM specifications. Rolled thread meets ASTM specifications with the exception of A325 and A490. However, one thing to remember is that Architects and Engineers often specify cut thread for anchor bolts. Cut thread can usually be substituted for rolled thread but the opposite may not always be true.
