		<description><![CDATA[Preload and bearing arrangement
Basically, there are two types of preloading:
Spring preload Characteristics:

Insensitive to different thermal expansion of shaft and housing
Suitable for very high speeds

The drawing shows a spindle where bearing 1 has a fixed location, whereas the outer ring of bearing 2 is free to move axially. The spring force acts on the outer ring of bearing 2 and results in a permanent preload of both bearings almost independent of speed and temperature factors. Care must be taken to ensure easy movement of the adjusted... <a href="http://www.rhdbearing.com/preload-and-bearing-arrangement/" class="read_more">Read the rest</a>]]></description>
