Planetary roller screw Spiracon™

Spiracon™

Converting rotary motion to linear movement, the system consists of a multi-start screw with an involute thread form and a number of planetary rollers with annular grooves, which engage with the screw.

The rollers also engage with a grooved load bearing element, which transmits the load through roller thrust bearings, to the nut housing.

The rolling action results in a high efciency mechanism, while the line contact and hardened and ground construction achieve a high dynamic load carrying capacity, together with almost no axial backlash or wear.

Go beyond the performance of ball screw with our highly efcient Spiracon™ planetary roller screw. It is a unique concept, to meet unique needs.

• Continuous duty

• High dynamic load capacity from 45 kN to 1200 kN

• High efciency, low noise

• High positional accuracy

• Long Life

• Low maintenance

• Nut Housings to customer specication that

can include features like Threaded End, B5-Flange, B14-Face, Trunnion etc.

• Screw journals manufactured to customer requirements.

Advantages over Ball Screws

• Higher dynamic load capacity

• Larger diameters and higher leads

• Higher positional accuracy

• Longer life

• Higher stiffness

• Higher speed and acceleration

• Low temperature operation

• Lower noise

• Nut easily removed with rollers retained

• Higher safety
