For single row four point ball slewing bearing (https://www.slew-bearing.com/Single-Row-Ball-Slewing-Bearing.html), there are mainly three materials, C45, 50Mn and 42CrMo. According to different applications and load conditions, it can select from above three materials accordingly. For C45, the har Read More

Current single row ball slewing bearing(https://www.slew-bearing.com/Single-Row-Ball-Internal-Gear-Slewing-Ring-for-Combination-Sewer-Cleaner-pd6849698.html) follows two industry standards JJ36.1-91 "Slewing Bearing for Construction Machinery" and JB/T 2300-2011 "Slewing Bearing". At present, except Read More

The single row four point contact ball bearing is composed of two seat rings, which design is compact structure and light weight, steel ball contact with the circular raceway at four point, it can bear the axial force, radial force and the tilting moment at the same time. It can be used for slewing Read More

A four-point contact ball bearing makes it easy to simplify machine designs that have a combination of radial, thrust and moment loads because it can handle all three simultaneously. They are primarily used for slow to moderate-speed applications, or where oscillatory movement is predominant. Read More

A static load bearing is the weight applied without any build up of energy, and therefore is to remain motionless. Force, pressure, and gravity remain static or are applied gradually. A dynamic load bearing is measured by the application of rapid force or pressure to an object.In static loading all Read More
