WD-H Series

Slewing ring bearing WD-H series, the middle "H" means heavy duty, so it is made for demanding applications. The WD-H series is fully enclosed, can withstand very high load and torque capacities, and has a very compact design. Also in many applications, such as steering, mining, tilt rotators, heavy positioners often have WD-H series applications.

The WD-H series offers much higher load carrying capacity than comparable slewing rings and utilizes a crossed roller bearing design. It is divided into two different raceways to achieve high load capacity in a compact package with maximum torque.
