(NSK; Headquarters: Tokyo, Japan; President and CEO: Norio Otsuka) today announced that it has developed Megapositioner™ units that deliver high-speed and precise rotary positioning of loads with a high moment of inertia*1 up to 700 kg·m2. The units incorporate NSK's own Megatorque motors and a zero backlash precision reducer. NSK will seek to increase sales of the units for manufacturing facilities that produce large components such as LCD panels, solar panels and automotive components.
