Energy Efficient Precision Ball Screw with Flanged Nut 1516 ETA+ Customizable • High precision for high loads with travel ranges up to 250 mm • Flanged single nut with ETA+ technology • Standard plastic wipers on both sides Description ETA+ Technology - Enormously high efficiency due to precision grinding process - Up to 50% less energy consumption - Outstanding longer lifetime over more million cycles The "ETA+" development from Steinmeyer comes very close to the ideal of power transmission from motor to carriage. Reduced friction combined with increased stiffness results in a significant increase in efficiency. A 50 percent improvement in stiffness and a reduction in friction of around two thirds are achieved. In addition, the reversal error is virtually eliminated, with the result that the ETA+ ball screw shows completely linear behavior under all conditions with regard to speed, load and direction of rotation.
