Slewing Bearing Numbering Method JB2300-99
The single-row four-point contact ball slew bearing is composed of two seat rings. It has a compact structure and light weight. The steel ball contacts the arc raceway at four points and can withstand axial force, radial force and overturning moment at the same time. Rotary conveyors, welding operators, small and medium-sized cranes, excavators and other construction machinery can be used.




Note
1,n1is the number of lubricating oil holes. Steel ball diameter<middle25oil cupM8x1(JB/T7940.1~JB/T7940.2);Steel ball diameter>middle25oil cupM10x1(JB/T7940.1~JB/T7940.2). The user can specify the oil hole location according to the application.
2,nMedium can be changed to thread diameter of threaded holeM, thread depth2M3, The gear circumferential force in the table is the maximum circumferential force, and the rated circumferential force is taken as1/24, "K” is the topping coefficient.
3. The specifications in this sample are standard products, and the inner and outer diameters are all within free tolerance. If there are coordination requirements between the host machine and the slewing bearing, please specify it in the contract or contract attachment.(Such as technical agreement)Indicate the fit size and accuracy.
