Roller Screw Jack Actuators Offer Efficient Alternative To Ball Screws

01 October 1999

Roller screw jack actuators offer efficient alternative to ball
screws




With an overall efficiency as high as 70%, a new range of roller screw
jack actuators from SKF Engineering Products are able to raise loads,
with the same power output, some three time greater than an equivalent
traditional friction based thread screw system. The actuators will also
transfer bigger loads faster than a friction thread based system without
overheating. The compact design is based on a worm gear driven,
self-contained rotating nut assembly. As the nut is rotated, the
inclusion of a spherical roller thrust bearing provides full support to
the roller screw nut assembly and ensures the load is evenly distributed.
The planetary motion of the rollers within the nut body eliminates any
relative axial movement, while continuously meshed rollers provide smooth
running.
