A slew drive is a type of gearbox 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 slew drive, slewing drive, turret bearing, worm drive, rotational unit, and many other slewing product labels.
Slew drives are an update to worm drive mechanisms and are made for applications that need rotational torque and load holding in the same gearbox. HZPT is an original equipment manufacturer (OEM) delivering a slew of customizable, high-quality, and competitively priced drives. We will work alongside you throughout the entire process, from design to implementation, to ensure total satisfaction.

Features of Slewing Drive
The slewing drive adopts the structure of slewing bearing and annular worm, which can achieve multi-tooth contact, has the characteristics of ample transmission torque and stable operation and can withstand large radial and axial loads and intense overturning moments.
Three advantages
- Modular
Due to the high integration of the slewing drive, the user does not have to purchase and process each component of the rotating device 1 by one, which also reduces the preparation process at the beginning of product production to a certain extent, thereby significantly improving labor productivity. - Safety
The worm gear drive has reverse self-locking characteristics, which can realize reverse self-locking. This feature makes the slewing drive widely used in lifting, aerial work, and other equipment. While improving the technological content of the main engine, it also dramatically improves the operation stability of the main machine and the safety factor of the operation. - Simplified mainframe design
Compared with traditional slewing products, the slewing drive is easy to install, maintain, and saves installation space to a greater extent.
Applications of Slewing Drive
Slew drive can be widely used for 360° rotating and speed shifting, ample torque smoothly transmission, high precision matching or compacted mechanism is mainly relied on slew drive, for its particular solution and widely application below:
- Heavy loading gantry crane
The slewing drive has changed the traditional mode of heavy loading gantry cranes in this field, significantly reducing operating and maintenance costs. It has been adopted by more and more host manufacturers of its effectiveness.
- Aerial work vehicle field
The slewing bearing motivates slewing drive, which has developed rapidly and has obvious advantages in this field.
- Heavy loading flatbed truck (beam truck)
Due to the heavy load, duplex worm slew drives widely provide ample output torque.
- Port cranes
While using a slew drive to fulfill the loading moment, the conventional hydraulic cylinder is another way to modify the rotating slewing ring.
- New energy field
With the support of national policies, the prospects of the rotary drive in this field are very impressive.
Custom Slewing Drives
HZPT provides its customers with a high-quality application-based slew drives product line. Sizes range from 7.5″ (200mm) up to 20″ (500mm) in ID. Standard hydraulic or electric motors rotate the drive-through standard worm shaft inputs and can be assembled upon customer request, depending on their application.
