Shuton is a leading company in the design and manufacture of high performance ball screws located in the Country, central focus and leader of the machine tool industry.
SHUTON preloaded compact nut ball screws offer many advantages:
Better alignment and concentricity of the whole nut with the screw.
Reduced nut length, thus less mass.
Elimination of the bearing holder parts in rotary nut designs.
Possibility of special designs, with compact nut-carrying bodies.
The preload is obtained by changing the lead of the thread in one single middle groove of the nut by means of CNC grinding. In this way, the nut of these ball screws consists of a single piece.
PRIME preloaded compact nut ball screw is designed with internal ball recirculation system 'S'. This is the normal recirculation for shorter leads. Each ball circuit is independent, and has its own S-shaped deflector.
The nut in double nut ball screws is comprised of two parts separated by a washer, the thickness of which determines the preload force.
At SHUTON these two parts are embedded, in order to eliminate potential radial displacement and improve the alignment and concentricity of both parts.
Double nut ball screw maintenance is very rapid, as it does not need to be dismounted from the machine.
COMPLEX double nut ball screw is designed with U external ball recirculation system, normally used for short lead Ph<20. Ball return is done via a recirculating tube assisted solely by two shaped deflectors.
