WEA series slewing units
Slewing drives for heavy-duty rotating applications
Slewing drives are used to create controlled rotary movement in applications where high torque, strong holding capacity and reliable positioning are required. JIE-Euronorm supplies WEA series slewing drives for heavy-duty machines, turntables, cranes, excavators, grippers and other industrial rotating systems.
The range includes slewing ring bearings with integrated worm gear and slewing ring drives with gearbox and electric motor. These drive solutions are designed for applications where significant axial force, tilting moment and output torque must be handled in a compact and robust construction.

How to choose the right slewing drive?
Choosing the right slewing drive depends on the required tilting moment, output torque, holding torque, ratio, output speed, mounting position and load conditions. JIE-Euronorm helps customers select the correct slewing drive based on the technical requirements of the machine, rotating structure or heavy-duty application.
- Required tilting moment in kNm
- Maximum output torque and holding torque
- Required ratio and output speed
- Axial, radial and tilting loads
- Motor type, gearbox or hydraulic drive requirements
- Positioning accuracy and environmental conditions
Options On The Slewing Drives
The WEA series slewing drives are designed for applications where controlled rotary movement, high torque and strong load capacity are required. The slewing ring bearing with integrated worm gear transmission combines bearing support and drive function in one compact unit.
This type of slewing drive is particularly suitable for heavy-duty applications where significant axial force, tilting moment and torque must be accommodated. Typical applications include industrial boat cranes, excavators, turntables, grippers and other rotating machine structures.
The integrated worm gear transmission makes it possible to achieve high torque at low rotational speeds. The worm gear design also contributes to the self-locking capability of the slewing drive, which can be important for positioning and holding loads.
The WEA series slewing ring bearings with integrated worm gear can be equipped with an IEC motor mounting flange or a hydraulic motor mounting flange. This makes the slewing drive flexible in use and suitable for different machine concepts and drive configurations.
There is also the option to mount a pre-stage to increase the transmission ratio. This can be useful in applications where precise positioning of the slewing bearing is required or where very low output speeds are needed.
The WEA series is available within the following scope:
- Outside diameter from 231 mm to 744 mm
- Ratio from 47 to 104
- Tilting moment from 14.2 kNm to 310 kNm
- Maximum output torque from 3.5 kNm to 34.2 kNm
- Maximum holding torque from 20 kNm to 158.3 kNm
- Maximum output speed up to 2.5 rpm, depending on the configuration

Frequently asked questions about slewing drives
A slewing drive is a compact rotary drive system that combines a slewing ring bearing with a drive mechanism, such as an integrated worm gear. It is used to create controlled rotation in machines and structures where high torque, strong holding capacity and reliable positioning are required.
The right slewing drive depends on the required tilting moment, output torque, holding torque, ratio, output speed, load direction and installation environment. JIE-Euronorm can help select the correct WEA slewing drive based on the technical requirements of the machine or rotating application.
