Mill Ball Screw XY Axes Retrofit Kit - Sherline Products
All screws come in at 400mm (15.75mm) long, and we cut them to length to fit the individual machine axis. All retrofits come with the stepper-motor mounts, high-torque couplings, bearings, preload nut, and ball screw fully assembled in our factory. We do not sell these parts individually for you to assemble.
