Slewing ring bearings, turntable bearings, small slew ring bearing The success of the Fenghe slewing ring is the result of the precision of our finishing by grinding. All our production is perfectly under control and the matching of the rings and the rolling elements, gives batch after batch, the certainty to obtain the right bearing for this very demanding application. We propose also motor torque bearings. Our tailor made design follows perfectly the specific requirements of the customers. Because of the light structure of the crane, the Fenghe slewing ring is an essential and strategic part. Our design matches perfectly the life time required by the customer. The quality and the precision of our manufacturing is the key to ensure good running after many cranes dismantling. In this application the Fenghe slewing ring helps construct buildings everyday all around the world with total security. According to different structural characteristics, slewing bearings can meet the needs of working hosts under different load conditions. Four-point contact ball slewing bearings have high dynamic load capacity. Crossed cylindrical roller slewing bearings have high static load capacity. Crossed tapered rollers The pre-interference energy of the sub-slewing bearing enables the bearing to have greater support rigidity and higher rotation accuracy. The three-row cylindrical roller combined slewing bearing leads to the improvement of the bearing capacity in the height direction of the bearing. The track and roller set bear, so under the same stress conditions, the diameter of the bearing can be greatly reduced, so it has the characteristics of making the host more compact.
