SlewingRing Bearings Slewing ring bearings can accommodate axial, radial and moment loads acting either singly or in combination and in anydirection. So they are widely applied on engineering machinery (Mobile crane, Tower type crane, Excavator, Loader), Metallurgical Machinery, TransportMachinery, Medical instruments, etc. Thecoding method of bearings The two coding methods of Slewing RingBearings are as following: 1. Adopt the stipulation of JBT2300standard, which use raceway center circle diameter, rolling element diameter, structure type, transmission type, assembly type and mounting hole type to showthe coding method of bearings. Slewing Ring . . JBT 2300 Mountinghole type :0.1.2.3 Assemblytype:0.1.2 Racewaycenter circle diameter
