(1)High Reliability
LIMON applies stringent quality control standards on every production process.With proper lubrication and use, trouble-free operation for an extended period of time is possible.
(2) The high efficiency of ball screw is vastly superior than conventional screws. It takes less than 30% torque to make the linear motion into rotary motion.
(3) High Rigidity and Preload
The ball screw of LIMON is designed with Gothic arch groove,which makes the screw easy to rotate even using minimum axial play. To make the rigidity more appropriate to using condition, you can change the preload between one or two screw nuts to reduce axial play.
