Compact SHUTON TC
SHUTON high-precision ballscrews with compact preloaded nut 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 high precision ballscrews consists of a single piece.
The compact nut can be mounted only with internal recirculation 'S'. This is the normal recirculation for shorter leads. Each ball circuit is independent, and has its own S-shaped deflector.
SHUTON recommends the use of a compact nut on short and medium ballscrews with small leads.
The following table shows the standard product range of high precision ballscrews with steel balls and a Compact Nut, with a maximum of circuits made according to the nominal diameter and lead:
