We see from your search that you're looking for information on the term "Roller Screws",
and we have a large number of manufacturers' news releases and technical articles here on Engineeringtalk which will be of interest.
Let me be your guide.
Start with
the news release Legacy products replaced or upgraded from
Power Jacks, which we summarised at the time by saying "Power Jacks can replace or upgrade a wide range of screw jacks, linear actuators and bevel gearboxes originally supplied with brand names other than its own".
Earlier in the week,
we featured the news release Overcoming the limitations of ballscrews from
Abssac: "Abssac reckons its satellite roller screws offer formidable advantages in the linear technology sector".
In November 2007, we covered the news from Abssac
concerning its Abssac satellite roller screws
- take a look at Satellite roller screw transmits high loads
which says: "The many points of contact give a satellite roller screw greater rigidity and shock tolerance than a ball screw without a compromise in friction or efficiency".
Take a look also at the news release from SKF UK, Roller screws help get satellites into space,
as well as Roller screws provide smooth motion from SKF UK,
and Recirculating roller screws aid cancer treatment from SKF UK.
