Magnetic conveyance unit
Magnetic conveyance unit
Koyo Machine Industries Co. Ltd has started marketing a conveyance unit that uses a magnetic screw utilising the magnetic force provided by a permanent magnet. In contrast with the ball screw using steel balls, the magnetic screw revolves by non-contact and requires no lubrication, so features excellent cleanliness and low noise, and since the screw shafts are linked in multiplex, long strokes are available which cannot be provided by ball screws. The magnetic screw is fitted magnetically on the inside of a magnetic nut and displays its screw function by utilising the attracting forces of the N and S poles generated between it and the screw shaft.
