Backlash-free star-shaped coupling ROTEX couplings can replace imported from Germany, the company mass-produced, exported to various countries. 

 XL star coupling the elastic element is plastic, as the engineering plastics with good flexibility, cushioning, shock absorption, abrasion resistance, thus a good compensation between the two drive shafts of various displacement , where widespread use, transfer torque 20 - 35000.NM temperature -35-- +80 degrees Celsius and with the German ROTEX coupling interchangeable. Polyurethane elastomer star coupling claw from the convex block limit, you can avoid the impact of internal deformation and centrifugal force generated by the external deformation produced; convex concave big claws, so that the involute tooth surface pressure on the small , even under the overload on the teeth, tooth still will not wear or deformation. Features: PC backlash-free connection to the next, for the spindle drive, lifting platforms and tools, etc.; axial plug-in assembly, easy to install the blind, to save time; small size, moment of inertia is small, maintenance-free; easy visual inspection. The middle of the elastic polyurethane material using the German formula, there are a variety of hardness are available. 
 Use: mainly used in CNC machine tool industry, textile industry, automated production lines, and high-precision positioning drive industry.
