Coresun Drive 21 inch products are usually used for large excavator and crane,because SC21 slewing drive has higher holding torque and tilting moment, it is the key point of heavy load equipment.Coresun Drive have improved the performance of worm shaft and end cap for 8 bolts to ensure the full strength on axis load for worm shaft side to add using life of slewing drive.
Coresun slewing drive advantage
SC series of products are the updated models of SD slewing drive. Reasonable and precise sealing structure are satisfied by the customers
Hourglass worm slewing drive is designed with much tooth contact surface between the worm and gear. The slewing bearing is machined by quenching treatment with stronger hardness, abrasive resistance and use life
Coresun use framework oil sealing on SC series of slewing drives. The sealing is made up of double lip arrangement, high quality steel and NBR. So SC slewing drive has the higher IP class.
SC slewing drive has the strong tilting moment torque and static self-locking function
