Planetenrollengewindetrieb
Spiracon Planetenrollen-Schrauben
Mit dem präzisionsgeschliffenen Spiracon™ Planetenrollengewindetrieb und den passenden Rollenmuttern übertreffen Sie die Leistung von Kugelgewindetrieben und erreichen die ultimative Leistung bei linearen Bewegungen.
Das Spiracon™ Planetenrollengewindesystem besteht aus einer mehrgängigen Schraube mit Evolventengewinde und mehreren Planetenrollen mit Ringnuten, die in die Schraube eingreifen. Diese hocheffizienten Konstruktionen verfügen über eine hohe Tragfähigkeit bei nahezu spielfreiem Axialspiel und hoher Lebensdauer. Ideal für Hochleistungsanwendungen, die einen echten Dauerbetrieb, hohe Effizienz, hohe Genauigkeit und hohe Geschwindigkeit erfordern.

Selecting the right Planetary Roller Screw
There are 3 simple steps to follow when selecting a Spiracon roller screw:
- Load, speed and life
- Critical speed, buckling and deflection
- Torque and power

Special Designs
The Spiracon™ Planetary Roller Screw design has successfully been applied in many varied ‘special’ applications, requiring for example:
- Specialist end machining on each end of roller screw
- Flange on end face of Roller Nut
- Threaded End on Roller Nut
- Trunnion mounts on roller nut
- Full power stop nut
- Spherical bearings located on roller nut end faces
- Stainless steel version
- Special custom designs available up to 1800kN

Roller Screw
The Spiracon™ Planetary Roller Screw system consists of a multi-start screw with an involute thread form and multiple planetary rollers with annular grooves engaging with the screw.
The rolling action results in a high efficiency mechanism, while the line contact and hardened and ground construction achieves a high dynamic load carrying capacity, combined with almost no axial backlash or wear and long life and low maintenance.
Where you need the ultimate performance in industries such as oil & gas, nuclear, defence, steel and automotive these roller screws deliver.
