When your application demands the ultimate in torque, rigidity, and operational safety, standard single-worm drives have a limit. Meet the WEA21-2 Slewing Drive, engineered with a dual-worm gear system to deliver unparalleled performance for the most challenging heavy-duty and safety-critical operations. This robust design eliminates internal bearing play, drastically reduces backlash, and provides true bi-directional self-locking for maximum security and precision.
The WEA21-2 builds upon the proven foundation of the WEA21 by incorporating two opposing worm gears that engage with the central slew bearing. the definitive choice where high moment loads, shock resistance, and pinpoint rotational accuracy are non-negotiable.Dual Worm Gear System: The core of its performance, providing balanced torque, superior stiffness, and near-zero backlash for precise motion control.
