Dual Worm Slew Bearing

Coresun@ slew drives are powered with hourglass worm technology for maximum gear torque and the smoothest rotation. Typical slew drive applications include solar industry, truck cranes, man lifts, utility equipment, hydraulic attachments, oil tool equipment, marine cranes, tire handlers, digger derricks and automotive lifts, but the slew drives are used in many other applications requiring load holding and rotational capability. We offer different slew drive models with different moment load capacities. The standard slew drives are fitted with an open housing and single self-locking hourglass worm shaft. Once the power source input is returned to neutral, the worm shaft will lock the load into position without requiring any external braking device.  

Production Description

High Torque heavy load double worm drive slewing bearing offered by Coresun Drive is widely used on mining equipment, truck crane, drilling rig, boom lift and turntable design.

Coresun Drive slew drive is a type of gearbox that is critically designed to handle high axial, radial, and tilting moment loads while providing high rotational output torque. Across different applications, a slew drive can also be known as worm gear drive, slewing drive, turret bearing, worm drive, rotational unit, and many other slewing product labels. The mechanics behind it is built on the concept of a worm wheel where a slewing ring with external teeth is meshed with complementing worm gear with a predefined gear ratio. Internal components are contained and assembled inside a cast iron or aluminum housing for protection and installation.  The unique design of coresun slew drive allows it to utilize two perpendicular planes transmitting high output rotational torque with a relative speed ratio to its inputs. As the worm gear rotates through a low input torque on the horizontal plane, its hardened teeth translate rotational motion onto the external slewing teeth. This force creates a rotation around the perpendicular axis of the slew drive through the slewing outer ring. The use of a worm-wheel design makes room for a wide range of low torque inputs to the slew drive to transmit or hold high torque applications. Slew drives can be found across several constructions and heavy machinery equipment. The versatility and weight allow slew drives to act as an immediate solution to rotary related issues.
