Slewing Drives and Bearings
Slewing Drives and Bearings for Low Profile Power
Cone Drive’s slewing drive and slewing bearing technology provide a large ratio in a single stage of
gearing. For additional torque, we offer the option of adding an inline planetary gear to create a double
reduction slewing drive. The slew bearings and drives are assembled into a low profile, self-retaining,
and ready-to-install housing, optimized for weight and performance. Our highly adaptable slewing
gearboxes feature strong shock resistance, long life performance, and smooth rotation.
As a global slew drive and slew bearing manufacturer, we have the capability to provide custom solutions for specific applications. We have a long and proud engineering history that started in 1925 and have worked to provide the most cutting-edge gearing technology ever since.

FAQ's
- What type of grease do I use in my slew drive/bearing?
- How often should I be greasing the drive/bearing?
- Can I rotate the drive with the hex opposite the input shaft?
-
Yes, a hand wheel or hand drill can be used to rotate the drive via the hex on the worm.
- Can we drive the slew with an AC/DC Motor?
-
Yes.
- What is the max speed I can run the slew drives?
-
W-Series: 3 rpm max output speed; S-Series: 1 rpm max output speed
- Do we offer special coatings for the slew drive/bearing?
-
Yes, additional corrosion protection options are available. Please contact ae@conedrive.com for more information.
- What is the efficiency of a slew drive?
-
Typical slew drive efficiency is about 30%.
- Do I need to use all the internal grease to grease bearing raceway?
-
Worm and raceway of slew drives should be greased per the IOM
- Is there an optimal orientation to mount the slew drive?
-
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
- Can I mount my slew drive horiztontally with the housing on bottom and seals facing upward?
-
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.
