Slew Drives
Smooth Rotating Performance
Cone Drive’s slew drive technology provides a large ratio in a single gearing stage. The slewing drives are assembled into a low profile, self-retaining, and ready-to-install housing, optimized for weight and performance. Our highly adaptable slew gearing features strong shock resistance, long life performance, and smooth rotation.
For applications driven by an electric motor, Cone Drive offers a double reduction slewing drive to provide a clean, efficient solution.

FAQ's
Yes, a hand wheel or hand drill can be used to rotate the drive via the hex on the worm.
W-Series: 3 rpm max output speed; S-Series: 1 rpm max output speed
Yes, additional corrosion protection options are available. Please contact ae@conedrive.com for more information.
Typical slew drive efficiency is about 30%.
Worm and raceway of slew drives should be greased per the IOM
Yes, when mounting the slew drive horizontally, it is always recommended to mount the drive with the housing on top and seals on bottom, when possible. When mounting vertically, it is recommended to mount in the worm over orientation
Yes, however a WEA or WEB version is recommended when mounting in this orientation for additional corrosion protection. Please contact ae@conedrive.com for more information.
