Combined Roller Bearings and Rails can readily be used in multi stage telescopic applications. Track bearings and rails are commonly used for the telescopic masts of fork lift trucks, but they are equally suited to horizontal applications (for example vehicle pull-outs or furnace lances) and even overhead situations as shown below.
Telescopic arrangements maximise the space available as the system can be designed to fully extended and neatly pack away.
This example shows a two rail system extending with a cantilevered load carried on the forks. Many other configurations are possible and sometimes it can be beneficial to use a four rail system, or a pair of two rail systems working simultaneously.
