7 Inch Hourglass Worm Small Backlash Slew Drive For Parabolic
Trough Power Station
Small Backlash Worm Gear Slewing Drive Description
Zero backlash worm gear slewing drives are mainly used in CSP
application like parabolic or trough, it is a kind of heat
condensor system which can absorb the heat to a certain chemical
and transfer the heat to electricity.
