Description

Material
Steel.
Version
Galvanised.
Note
Roller carriage with low coefficient of friction, therefore very free-running. The roller journals are lifetime-lubricated and have a 2Z (dust cover) seal. By simply moving the centre cam roller, the roller carriage can adjusted to be play-free or under the desired initial tension in the rail. The compact version has a plastic stripper for cleaning the tracks.

Application temperature -30 °C to +120 °C.
