needle roller bearings support high speed, high radial loads in confined spaces. spherical roller bearings support heavy shock loads where misalignment is a risk, such as wind turbines, pumps, paper processing, and fans. tapered roller bearing cones and cups support high radial and axial loads and are used for such things as axels and gear boxes.
the bearing seat we produce include split and intergrated bearing seat,they are mainly used in the large heavy industrial machinery such as rotary kiln, ball mill, steam turbine and so on.gray casting iron are widely used in the bearing seat,after casting the material need to anneal, which can effectively improve the usability of the bearing seat.
