SDE21 Gear Ratio 125 / 1 Hourglass Worm Gear Slew Drive With Enclosed Housing For CPV
Worm Gear Slew Drive Description
Slew drives are used for concurrent transmission of axial and radial forces as well as transmission of tilting moments. Slew drives consist of a ball or roller slewing ring, hydraulic or electric drives, and a completely enclosed housing. Series SE slew drives are designed with worm gear.
SDE3,SDE7,SDE21 ISO9001/CE certificated slew drive worm gear for sun tracker
1) Higher output torque and holding load
2) Top tracking precision
3) Strong corrosion resistance and sealing effective
