Product Info

The WEA series slew bearings with integrated worm gear transmission can be equipped with an IEC or hydraulic motor mounting flange, making it versatile in application.

This type of slew bearing is particularly used in ‘heavy-duty’ applications where significant axial force and torque need to be accommodated. Examples include industrial boat cranes, excavators, turntables, and grippers.

The integrated worm gear transmission enables achieving high torque at low rotational speeds, and the worm also contributes to the self-locking capability of the slew bearing.

There is also the option to mount a pre-stage to increase the transmission, which can be applied in applications where precise positioning of the slew bearing is crucial.
