Slewing ring is nearly four decades in the world gradual rise of new mechanical parts, it has inner and outer rings, rolling, etc., at present, China's production of slewing stereotypes, mainly in the early 1980s designated by the Ministry of Machinery Industry, Tianjin Engineering Institute of Mechanical former Federal Republic of Germany to introduce the organization Rothe Erde's design and manufacturing technology. December 20, 1984 released the People's Republic of China Ministry of Machinery Industry Standards: JB/2300-84 "slewing Types, basic parameters and technical requirements", mainly by the Ministry of Machinery and Electronics Industry, Tianjin Institute of Mechanical Engineering, responsible for drafting, and later the State has released a standard construction machinery in 1991: JB36.1-36.3-91, in 1999 and 2011 has released new machinery industry standard JB/2300-1999 and JB/2300-2011. Deep groove ball bearings (rolling bearings), when the radial load rolling mill rolls by four (pairs) cylindrical roller bearing load, this type of roller bearings as an auxiliary drive end bearing and bear part of the axial load. The positioning accuracy is not strictly mill, this type of bearing can also be used as locating bearings. This type of bearing axial clearance is about 5-7 times the radial clearance.
