SD Rotation Drives w/Bearings
Perfection Gear
SD style swing drives provide a cost effective solution to rotational application requirements.
The SD swing drive incorporates a slewing ring bearing in the drive system housing, providing ease of assembly and minimizes interface surface machining. Pre-set backlash in these swing drives eliminates the adjustment error that occurs during assembly of other rotation drives and slew rings. The SD provides a cost effective solution to rotational application requirements.
Key Features
- Rugged construction, able to withstand high shock loads and overturning moments that are common to crane usage
- Motor can be mounted at either end
