The specification type of the inversion drive pair is different; the specification type is divided into the approximate raceway diameter of the reverse support: WD-080, WD-0130, WD-0170, WD-0223, WD-0343, WD-0419, WD-0478, WD-0625 and other specifications; domestic type naming specifications according to the approximate raceway diameter of the reverse support; in inches (1 inch = 25.4mm), divided into: SE3, SE5, SE7, SE9, SE12, SE14, SE17, SE21, SE25 and other specifications. The "WD" in the foreign type designation means: Worm and Drive English abbreviation, "SE" in the domestic type designation: Slewing and Enclose English abbreviation. Which method is named; the corresponding device scale and performance parameters of each type are the same.
At present, there is no consistent specification for the recognition of the type of practice used by the inversion drive pair in the solar industry; most of them are based on the practical use area of ​​solar panels to determine the selection; more than the accepted norms are named after the domestic type: the practice of SE3 Solar panels use area: 3-5 m2, SE5 at 6-9 m2, SE7 at 10-17 m2, SE9 at 18-30 m2, SE12 at 31-45 m2, SE14 at 46-60 m2, SE17 at 61 -95 m2, SE21 at 96-120 m2, SE25 at 120-160 m2; of course this is not a definite specification; for reference.
The main components of the reverse drive pair are: reverse bearing, worm, casting base and some standard parts such as bearings, bolts, etc. In the solar photovoltaic power generation occupation; reverse drive equipment, a phase-matched DC planetary gear motor or communication geared motor In the construction machinery, the hydraulic motor is mainly used as the power drive system.

Reflective Intermix Glass Beads, used in road marking paint and traffic signs,is important in mantaining visibility of motorist for driving under dim light or bad weather. used in highway ,arrport runway, pavement marking line, zebra crossing in traffice road line, road marking as reflective materials.
Road Marking Beads Reflective are solid, spherical glass beads for use with road marking materials such as Road and Line Marking Paint Water Based, Solvent Based and Thermoplastic.
Solid glass beads for use with road marking compounds, Class A and Class B are high quality glass microspheres resulting from the specialised processing of selected glass culet.
Road Marking Paint Reflective Glass Beads are a major factor in increasing road safety in an economical manner. Thanks to the beads` retro-reflective action at night, a vehicles headlight beam is returned to the drivers eye.
The microspheres not only multiply the visibility of the markings at night, but also increase the markings durability in general. Road Marking Reflective Glass Beads are used as a drop agent and as premix beads for road marking materials.
CHARACTERISTICS:
Increase visibility of road markings at night, High durability.
