We see from your search that you're looking for information on the term "Rolling Elements",
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 Cages have bearing on performance and reliability from
Victrex USA, which we summarised at the time by saying "Polymer is chosen for bearing cages because of its combination of strength and flexibility, high operating temperatures, high chemical and wear resistance and ease of processing".
A few weeks before,
we featured the news release Choosing the right bearing coating from
Schaeffler (UK): "Dr Steve Lacey, Schaeffler UK Engineering Manager, discusses the importance of selecting the right coating or corrosion-resistant material for rolling bearings operating in harsh environments".
In October 2007, we covered the news from SKF UK
concerning its SKF roller screws
- take a look at Roller screws help get satellites into space
which says: "SKF roller screws have to withstand intense vibrations, very high temperatures and extreme temperature fluctuations, and be able to operate within a vacuum".
Take a look also at the news release from Micromech, Ceramic bearings provide long life,
as well as Bearings offer increased lifespans from Schaeffler (UK),
and Equipment monitors bearing condition from IFM Electronic.
