Power Jacks Spiracon Roller Screws - Manual

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 efficiency 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.
